Linux-инфраструктура особенно выделяется своей сложностью как для атакующих, так и для ИБ-специалистов, защищающих её.

Его нужно проводить по каждой системе отдельно, и в крупной инфраструктуре с сотнями серверов это кардинально меняет экономику проверки.

Что изучать и на что обращать вниманиеПервое, с чего стоит начинать на каждой системе, — список процессов и сетевых соединений.

Специфика закрепления в Linux-системахЗлоумышленники используют специальный набор техник для закрепления в Linux-инфраструктуре, и часть из них сложно обнаружить стандартными средствами.

Как и в других отраслях, использование ИИ — один из путей снижения издержек и роста производительности труда.

К тому же для ИТ-отрасли, которая активно предлагает продукты с ИИ, не использовать такие средства самой было бы просто нелогично.

Владимир Лавров поделился опытом использования ИИ как для оптимизации бизнес-процессов, так и для ускорения разработки.

Поэтому нужно сначала выстроить методологию, платформу и инфраструктуру, затем определить задачи для ИИ и только после этого масштабировать автоматизацию.

Некоторые показатели внедрения ИИ в российских компанияхТакже использование ИИ создаёт большие риски в сфере подготовки кадров.

Для ЦОДов такой механизм может ускорить запуск новых площадок, но не отменяет требования к непрерывности их работы.

Она также поможет ускорить ввод и не ждать строительства дополнительных электростанций и сетей.

Надёжность всего дорожеКак именно IV категория надёжности в качестве сценария запуска ЦОДов повлияет на стоимость их сервисов, рынок пока только считает.

ВыводыIV категория надёжности не отменяет требования ЦОДа к непрерывности работы — она переносит часть задачи с внешней энергосистемы на самого оператора.

Выбор СУБД: универсальность против специализацииБудущее за универсальными СУБД, где есть и транзакционная, и аналитическая часть, или специализация останется?

Алексей Викулин согласился, что всё идёт от задачи, но большинство задач бизнеса соединяют потребность и в аналитике, и в транзакциях.

К SQL Server совместимость 98%, и к ним прилагаются компоненты инфраструктуры вроде Service Broker и SSRS (SQL Server Reporting Services).

Ретейл — цель номер одинНа ретейл приходится около 25 % всех утечек данных в России и 33 % в мире: больше, чем на любую другую отрасль.

У среднего ретейлера сотни интеграций, многие из которых давно забыты и не обновляются.

Полномочия сервиса рассчитываются централизованно и передаются в самом токене, а не зашиваются в конфигурацию.

Готовое решение обходится бизнесу выгоднее самописной логики на фронте и при этом делает вход проще, а не сложнее.

Он значительно усиливает защиту данных, передаваемых между аутентификатором и сервером, от перехвата и служит для входа в почту, CRM-систему и корпоративный VPN.

Network Access Control перестал быть экзотикой и стал инструментом, который определяет, кто и что попадает в сеть, куда и на каких условиях.

Станислав Калабин согласился и добавил, что NAC всегда работает в комплексе с сетевым оборудованием и не может быть самостоятельным решением.

Появились разнородные устройства и несколько видов подключений, которые нужно контролировать, и без централизованного инструмента, который даёт картину и позволяет управлять, мониторить и реагировать, уже сложно.

подозрений на киберинциденты, что в свою очередь уже на 40% больше, чем в прошлом году.

Например, во время сбоя в работе СДЭК в мае 2024 года хакерская группировка Head Mare публично заявила о взломе инфраструктуры компании и разместила скриншоты в подтверждение своих слов.

В результате вопросы возникли не только к надёжности сервиса, но и к тому, насколько точно компания описывает происходящее.

Тему подхватили СМИ, что в итоге сформировало негативное инфополе вокруг бренда.

После кибератаки у ритейлера возникли сбои в работе сайта, приложения и оборудования в магазинах, очереди на кассах и путаница с ценами.

Денис Солоничкин отметил, что начались реальные внедрения: операционные системы больше не покупают «в стол», это видно по нагрузке на техподдержку и по продажам.

Разбираемся, чем агент отличается от чат-бота и автоматизации, как его применяют в разработке и администрировании и какие риски возникают при доступе к корпоративным системам.

Он описывает, как агенты разных систем находят друг друга, обмениваются задачами и результатами и обрабатывают ошибки.

Поэтому к взаимодействию между агентами применяют те же принципы, что и к работе с инструментами: минимальные права, проверку входных и выходных данных, журналирование.

Как агенты меняют разработку ПОПри наличии разрешений агент работает с репозиторием, инструментами сборки и тестирования, закрывая многоэтапные задачи целиком.

При этом результат работы агента нужно проверять не только на ошибки, но и …

Наталья Глинина отметила, что стратегия должна отвечать на вопрос, с какими бизнес-рисками работает компания, и обязательно связывать цели ИБ с целями бизнеса.

Евгений Акимов предложил смотреть на стратегию как на ожидание бизнеса от кибербезопасности: если бизнес ничего не ждёт, стратегия не нужна.

Евгений Акимов:«Прежде чем писать стратегию, нужно разобраться с целями бизнеса, а не с требованиями к кибербезопасности.

Елизавета Комарова:«Нужно учитывать, что угроза — это не то, что маячит на горизонте, а то, что происходит прямо сейчас.

Эксперты сошлись в том, что стратегия должна фокусироваться на критических процессах и их восстановлении, а не на перечне приобретаемых решений.

Я изучила российскую законодательную базу по ИИ в части страхования и сравнила её с тем, как страхование ИИ-рисков устроено за рубежом.

Национальная стратегия развития ИИ до 2030 года и Кодекс этики в сфере ИИ закрепляют принцип: ответственность должны нести человек или организация.

Концепция развития регулирования ИИ и робототехники до 2024 года прямо называла способы возмещения вреда от ИИ: страхование ответственности и компенсационные фонды.

Отчёт об инциденте AISI опубликовал в августе, а в октябре вышли подробные разборы причин от самого института и от Anthropic (см.

Обратите внимание и на логику aiSure: страховщик платит по данным о работе модели, а не по итогам спора о вине.

Инцидент вроде бы закрыли, отчитались, выдохнули — а через пару недель выясняется, что атакующий никуда не уходил.

Инцидент растянулся почти на три месяца, и повторная компрометация случилась уже после того, как были приняты меры.

Оба сайта работают под одним пользователем <пользователь> и в общей файловой системе.

Переразвёртывание не удаляет файлы из общей ФС и не проверяет cron и systemd — точки закрепления переживают «пересоздание» окружения.

И это, пожалуй, главный урок нашего инцидента: иногда самые очевидные меры реагирования лечат симптом, а не болезнь, и тогда злоумышленник возвращается — тихо, спустя недели, как будто никакой реакции и не было.

Мы еще не знали, что на той стороне провода вместо сонных маркетологов к рулю уже встают безопасники.

Маркетинговые бюджеты урезали, а промокоды превратились в жалкую насмешку: «скидка 300 рублей при заказе от 3 500 рублей на товары без акций».

Физические сим-карты и прогретые аккаунты с историей заказов, которые стоят уже не 5 рублей, а по 150–300 рублей за штуку и живут ровно один заказ.

В README написано, что G в названии официально от GPT, а неофициально ещё и от Greg.

Ну а S в Ginux, как и в IoT, от Security.

Сначала модель угроз, затем три независимых прохода поиска: вслепую, от модели угроз и от истории CVE.

Пока мои отчёты превращались в PR для Ginux, Линус выпускал v7.4-rc1 с моим патчем.

А G, похоже, всё-таки от Greg: мой патч в Linux принимал один Грег, в Ginux — агенты другого.

Мы живём в другой парадигме, где архитектура диктуется не просто рисками галлюцинаций LLM, а еще и технологическим суверенитетом.

Теперь она пишется не для ARB, а для машин.

Fitness functions описывают то, что не попадет в мастер, а токены делегирования — то, чего агент не сможет сделать сверх задачи пользователя.

Default-off, точки перехвата человеком, поведение при отказе, лимит токенов, exit path — каждый пункт очерчивает границу, а не маршрут.

Архитектор теперь проектирует не только поведение системы, но и место, где ответственность за дальнейшее решение переходит от машины к человеку.

В самом инциденте (который в отчёте фигурирует как russian espionage) по данным Anthropic в планировании, разведке и атаках фигурировали более 20 организаций.

Злоумышленники использовали Claude для разработки и изменения инструментов, подготовки фишинговой инфраструктуры, сбора данных и управления отдельными этапами операций.

Но при организации испытания вкралась ошибка конфигурации, и на самом деле тестовая среда всё-таки могла подключаться к настоящим внешним сервисам.

Но пакет оказался в настоящем PyPI, и примерно за час его скачали и запустили на 15 реальных системах.

Что могло помочь и что делать для защиты: есть три защитных механизма, и они напрямую связаны с историей выше.

Весь конвейер «чтение → маскирование → запись» выдаёт на нашем стенде до 300 тысяч строк в секунду, и перестановка в нём не узкое место.

Переставлять целиком, а не по частям.

Подмножество сужается и на входе, и на выходе, поэтому отображение остаётся биекцией.

У FF1 десять раундов, и в каждом половины переводятся между строкой цифр и числом, а у нас восемь раундов из вызова AES и XOR.

Перестановка, заданная ключом, даёт уникальность и согласованность между таблицами без поиска по приёмнику и координации потоков.

Мне интереснее другое: задачи по безопасности у нас месяцами лежат в бэклоге, а ноутбук инженера с доступом в прод остаётся самым удобным входом в компанию.

Почему это касается не только биржЦепочка «ноутбук инженера → контейнер в проде → действие, которое не откатить» есть почти в любой компании.

Когда инженер со своей машины ходит в прод, в логах это выглядит как обычная работа.

Пересмотреть, у кого есть доступ в прод и exec в поды критичных сервисов.

Договориться с ИБ о регулярной короткой встрече и о том, что новые проекты они видят на этапе дизайна.

Сам факт того, что ИИ способен обнаружить уязвимость, еще не означает, что неподготовленный человек сможет воспользоваться этой возможностью.

Особенность этих уязвимостей заключалась в том, что они находились не в конкретном пользовательском приложении, а непосредственно в интерпретаторе, причем в механизмах, которые участвуют в обработке огромного количества запросов.

Разработчики не могли выбрать решение, которое одновременно устраняло бы проблему и не создавало существенных побочных последствий.

PHP Foundation впоследствии прямо признала, что задержка была связана не только с технической сложностью, но и с недостатками организации работы и ограниченностью ресурсов команды.

Следовательно,…

Как вы докажете проверяющему, что эти четыре строки пришли с web-1 в 07:28 и с тех пор их никто не трогал, вы в том числе?

Сначала строки взломщика попали в хранилище, потом файл подменили.

Если сборщик убить посреди работы, он продолжит с буфера, и ни одна строка не получит второй номер и не пропадёт.

Виртуальную машину сборщика подняли из снимка недельной давности: буфер вернулся в прошлое, хранилище нет, и новые строки получают номера, которые хранилище уже отдало другим.

Отдельная симуляция играет за нечестного владельца: придерживает записи и токены, подсовывает копии старых токенов, ставит звеньям время задним числом.

Косвенное подтверждение того, что работала та же рука, что и в прошлых кампаниях, дала блокчейн-аналитика TRM Labs.

Почему украденное - это военный бюджетДальше начинается часть, из-за которой событие попало в разбор недели индекса риска, а не в криптоновости.

В его власти немногое: не держать всё на одной площадке и не держать на бирже то, что не планируется продавать в ближайший месяц.

Не держать на бирже то, что не планируете продавать в ближайший месяц, и не концентрировать всё на одной площадке.

Не торговать на панике вокруг взлома: движение цены в такие дни - реакция на новость, а не на изменения в самой технологии.

Сейчас в ЕВРАЗе довольно строгие регламенты по части информационной безопасности — всё, как принято в корпоративном секторе.

Как мы работаем с кейсами разработчиковВозвращаясь к вопросу, который мне задают на ИТ-конференциях: «Как вы заставили их так работать?».

А человек нам доказывал, что это не так, и мы не могли взломать, раз не знаем, как он устроен.

В частности, как контролировать информацию, которую люди передают в ИИ, и как быть с тем же вайбкодингом.

Мы постоянно думаем, как это лучше отслеживать с нашей стороны, — не запрещая всё на корню, но упреждая риски информационной безопасности.

Через маркетплейс расширений для Cursor на протяжении почти 12 часов распространялась вредоносная версия официального расширения Anthropic Claude Code.

То есть пока остается неясным, каким образом злоумышленники получили возможность опубликовать вредоносное расширение под легитимным ID anthropic.claude-code на маркетплейсе Cursor.

Малварь запускалась автоматически при загрузке расширения и не требовала никаких действий со стороны пользователя.

Однако даже в этом случае расширение успевало добавить ключ злоумышленников в ~/.ssh/authorized_keys, зарепиться в системе и отправить собранные данные своим операторам.

ИБ-исследователь Марк Бла (Mark Blah) опубликовал в открытом доступе PoC-эксплоит для недавно исправленной в Android уязвимости CVE-2026-58882, также получившей название SMS of Death.

По словам специалиста, эта уязвимость относится к классу zero-click DoS и может прервать уже идущий звонок, включая вызов экстренных служб.

Более того, Android обрабатывает вредоносное сообщение до того, как оно попадает во входящие, поэтому пользователь не видит само SMS и не понимает, что именно послужило причиной сбоя.

В результате атакующий может передать специально сформированное восьмибайтовое WAP Push-сообщение «01 06 88 80 80 80 00 BE».

Исследователь отмечает, что во время тестов 20 таких сообщений уво…

Все статьи, PDF-архив, скидки и другие бонусыРазработчики Warp сообщили об атаке на стороннего подрядчика, связанного с инфраструктурой платформы.

В результате злоумышленники могли получить доступ к логам работы ИИ-агентов и пользовательской телеметрии.

Платформа объединяет терминал, редактор кода, инструменты для управления задачами и проверки работы агентов.

При этом в компании пока не уточняют, содержали ли скомпрометированные данные исходный код проектов, промпты, учетные данные или другую конфиденциальную информацию.

На прошлой неделе ее создатели предупредили об утечке API-ключей, которые пользователи сохраняли для работы со сторонними провайдерами.

Платформа Polymarket временно остановила торги после того, как хакеры скомпрометировали сторонний сервис DebugBear и распространили через него вредоносный JavaScript.

На время проведения расследования Polymarket сначала перешел в режим cancel-only, запретив новые сделки, а затем приостановил операции через релеи.

Анализ вредоносного скрипта показал, что тот проверял, авторизован ли посетитель в Polymarket, а при наличии активной сессии использовал штатные торговые функции платформы для несанкционированных операций.

Вредонос определял балансы кошельков и позиции пользователя на рынках прогнозов, после чего выбирал способ кражи криптовалюты в зависимости от метода аутентификации.

По информации РБК, в Минцифры работают над новыми правилами для смартфонов, ввезенных в Россию без таможенного оформления.

«При отказе от регистрации по истечении установленного срока такие устройства не будут обслуживаться в сетях», — пояснили в Минцифры.

Отмечается, что легальный ретейл эти изменения практически не затронут, так как IMEI официально ввезенных в Россию смартфонов будут попадать в централизованную базу автоматически.

Ранее сообщалось, что соответствующие требования могут начать действовать в 2027 году, а с 2028 года в мобильных сетях смогут работать только зарегистрированные телефоны.

Кроме того, за обязательную регистрацию устройств предлагалось взимать фиксированную плату,…

Эксперты «Лаборатории Касперского» обнаружили DoS-уязвимость в IP-камерах Intelbras.

Из-за ошибки в механизме обновления прошивки неаутентифицированный злоумышленник мог добиться временного отключения камер.

Как объясняют исследователи, обычно для управления камерой требуется пройти аутентификацию, однако в случае Intelbras эндпоинт, отвечающий за обновление прошивки, не проверял наличие авторизованной сессии.

В результате устройство пропадало из сети, приложение Intelbras теряло с ним связь, а пользователь не мог просмотреть трансляцию и управлять камерой.

По данным представителей Intelbras, эта же версия прошивки совместима с моделями iMX C, iM4 C, iM5 SC, iME 360 C и iM7+ FC.

Криптобиржа Binance расследует взлом, ущерб от которого в настоящий момент оценивается в 6,3 млрд долларов США.

Если сумма ущерба подтвердится, этот инцидент станет крупнейшим криптоограблением в истории: предыдущий рекорд принадлежал криптобирже Bybit, у которой северокорейские хакеры похитили около 1,5 млрд долларов США в феврале 2025 года.

Только в Ethereum хакеры получили активы примерно на 3,79 млрд долларов, а из биткоин-кошелька Binance похитили 18 270 BTC стоимостью около 1,47 млрд долларов США (по курсу на момент атаки).

В Binance рассчитывают полностью возобновить вывод средств в течение 48 часов.

По последней оценке экспертов самой Binance, суммарно удалось заморозить украденные …

Onamae.com — бренд компании GMO Internet, под которым работает один из крупнейших сервисов регистрации доменов в Японии.

Также в компании сообщили, что хакеры потребовали выкуп в размере 8 млрд иен, и представители GMO подчеркнули, что не станут платить злоумышленникам.

Позже в компании сообщили, что злоумышленники сдержали свое обещание и 27 октября действительно опубликовали данные, якобы принадлежащие GMO и ее клиентам.

В компании отказались платить выкуп хакерам, но пообещали компенсировать клиентам причиненный атакой ущерб.

Параллельно с этим в GMO объявили вознаграждение до миллиона долларов США за информацию, которая поможет поймать стоявших за атакой хакеров.

Представители Discord объявили, что сообщения из публичных сообществ скоро начнут появляться в поисковой выдаче Google и других поисковиков.

С середины декабря 2026 года на таких страницах начнут появляться отдельные сообщения из публичных каналов, которые смогут индексировать поисковики.

При этом старые сообщения, опубликованные до запуска функции, в поисковую выдачу не попадут, и на страницах не будут отображаться имена и аватары авторов.

Однако изменение настроек повлияет только на будущие сообщения, а уже опубликованную переписку можно будет убрать из открытого доступа, только удалив соответствующие сообщения из Discord.

Чтобы их сообщения могли появляться на Server Web Pages и индексир…

Из-за уязвимости контролируемый хакером сервер мог подменять неподтвержденные транзакции в истории кошелька.

Если пользователь не замечал подмены и пытался ускорить перевод, повысив комиссию, Electrum создавал новую транзакцию с адресом атакующего вместо настоящего получателя.

Корень бага заключался в том, что Electrum работает как легкий клиент и получает данные о транзакциях через сеть Electrum-серверов, которые могут запускать сторонние операторы.

Также было недостаточно и самой подмены: кража происходила только в том случае, если жертва вручную увеличивала комиссию и подтверждала измененную транзакцию.

В Electrum 4.8.3, вышедшей 24 октября, разработчики добавили проверку подписей для не…

Two critical flaws in Langflow could let a remote attacker with no account bypass authentication or run arbitrary code, IBM said last week.

Six other Langflow flaws are listed there, most recently CVE-2026-9198, which was added in August.

Its author lists Langflow 1.5.0 through 1.11.4 as affected, a narrower range than IBM's.

On October 29, IBM also published CVE records for 29 other Langflow flaws and named versions 1.12.4 and 1.12.5 as their fixes.

One of them, CVE-2026-104339, could also let an attacker with no account run arbitrary code, and IBM rates it 9.8.

AI SOC readiness has two parts: whether a SOC has the problems AI SOC agents are built for, and whether it has the data access, context, written standards and oversight rules that AI agents need to investigate alerts accurately in its environment.

Attackers posing as IT support on Microsoft Teams talked employees into giving them remote control of their PCs.

Microsoft said in a report that it investigated two such intrusions, one of which resulted in company data being copied to an external server.

With that kind of template, the requester can name the account the certificate will represent, so a low-privileged user can request one that stands in for a privileged account.

One privileged account, though, had been left out of the automatic response, so it stayed usable.

Cybersecurity researchers have disclosed details of a cyber espionage campaign specifically targeting Linux infrastructure associated with government entities and state-affiliated infrastructure.

"The attackers attempted to dump sensitive databases and exfiltrate government mailboxes to access social media accounts."

The campaign employs a "versatile operational playbook," leveraging a combination of open-source tools, custom cross-platform backdoors, and web shells to maintain access.

The threat actor has also been observed using malicious PHP and shell scripts, likely generated using AI, to maintain persistence, perform reconnaissance, and exfiltrate data.

Cybersecurity researchers have discovered a new Windows infostealer malware called VOLTA-AUTODOXER (aka VOLTA) that makes use of a large language model (LLM) to rank a victim's stolen data by their monetization value.

"VOLTA builds a structured evidence bundle about the person behind the machine," Cisco Talos researcher Ryan Fetterman said.

The requests are defaulted to Anthropic's Claude Opus 4.6, failing which it falls back to Moonshot AI's Kimi K2 and Google's Gemini 2.5 Flash.

"If VOLTA is indeed a commoditized malware, then the AI dossier capability isn't something the author invented for their own operations," Talos said.

"VOLTA is a mature stealer with a late-stage AI layer added for…

A critical flaw in Canonical's LXD and MicroCloud let an attacker log in as a trusted client without holding that client's private key.

The flaw, tracked as CVE-2026-112816, carries a maximum CVSS score of 10.0, and Canonical has released fixed versions of both products.

A standalone LXD server does not expose that API by default.

Canonical lists these fixed snap versions:Product Snap channel Fixed version LXD 6/stable 6.10.1 LXD 5.21/stable 5.21.9 LXD 5.0/stable 5.0.11 LXD 4.0/stable 4.0.15 MicroCloud 3/stable 3.4.1 MicroCloud 2/stable 2.1.5The bug did not start at Canonical.

On a snap install, run sudo snap refresh lxd and sudo snap refresh microcloud.

Malicious code on the website of prediction market Polymarket sold some signed-in traders' positions and moved their funds to the hackers on October 29.

Researchers at Hudson Rock downloaded the malicious file on October 29 from the address Polymarket's site used to load the DebugBear script.

They also found a change in Polymarket's site code that removed the DebugBear script.

Each DebugBear customer loads its own copy of the script, and the file that was swapped was Polymarket's.

For accounts that sign in with their own crypto wallet, it moves the trader's positions straight to the hackers' wallet.

AppDomainManager injection is an adversarial technique used to load arbitrary payloads by hijacking .NET Framework's AppDomainManager mechanism when a .NET application starts.

The FBI, along with the U.S. Secret Service (USSS) and the Internal Revenue Service Criminal Investigation (IRS-CI), said it observed the threat actor converting stolen assets primarily into Ethereum (ETH).

The agency has also provided a list of wallet addresses that the attackers are said to be using to launder the stolen assets.

The haul eclipses the $1.46 billion plundered from Bybit in February 2025, making it the largest cryptocurrency theft in history.

Of the $6.43 billion stolen by TraderTraitor, $2.85 billion of the assets have been frozen on-chain by Tether, Circle, Ripple, Arbitrum, and Optimism.

American blockchain analysis firm Chainalysis said it was the target of a cybersecurity incident in which an external actor accessed non-sensitive customer data.

However, the company noted that the breach did not result in unauthorized access to its investigation content, authentication credentials, or session tokens.

A malicious ChatGPT share link could run an attacker's code in the logged-in session of anyone who opened it, allowing them to read their private conversations, researchers at the security firm Parameter showed.

It could be sent the same way as any real shared chat: by email, as a chat message, as a support ticket, or as a social post.

What the Attacker Could DoOnce the link opened, the attacker's code ran inside the victim's signed-in session with the same access as the real ChatGPT site.

Because that page can hold any code, ChatGPT runs it in a locked-down frame on a separate web address, where it cannot read the main ChatGPT page around it.

The shared chat also contained an interactive g…

Amatera – which topped ESET’s infostealer detections in Latin America in the first half of 2026 but targets victims worldwide – shows what this professionalization looks like in practice.

Detected by ESET products as Win/PSW.Amatera, Amatera is a Windows infostealer written in C++ that was first observed in 2024.

Amatera has spread via compromised websites, search engine ads, targeted emails, fake documents, SVG files, and ClickFix via fake CAPTCHAs.

In Latin America, Amatera topped ESET’s infostealer detections in the first half of 2026, ahead of Formbook, Vidar, Lumma Stealer, SnakeStealer, and Rhadamanthys.

In the age of AI, all of this was reported within a single “Cybersecurity Black Week,” an exceptionally eventful seven-day period amid an already turbulent Black October.

The name refers to two memory-safety vulnerabilities in PHP core, CVE-2026-109618 and CVE-2026-109619, affecting PHP versions 5.4 through 8.5.11.

The same decoder is compiled into the Python Brotli and brotlicffi packages as well as into other HTTP software, which led researchers to rename the issue HTTP2Shell.

Cutting through the noiseCybersecurity Black Week showed that a severity score rarely tells the whole story.

For the leaked kernel flaws, that window opened before any fix existed, and for end-of-life PHP versions, …

The news prompted security advisories from government agencies and sent website owners scrambling to apply the patches, with some sites even going offline as a precaution.

This is because on an unpatched server, an attacker can exploit the vulnerabilities to run their own code without logging in.

Blockchain analytics firm Chainalysis has suffered a cybersecurity incident that led to a data breach.

In October, the company detected external attackers using “offensive agentic techniques” to gain access to Chainalysis systems and internal tools.

However, the attackers managed to access some customer (user) IDs, full names, email addresses, and organization role labels for users provisioned on the company’s platform.

Chainalysis did not elaborate further on the offensive agentic techniques used by the attackers.

“Our investigators are observing never-seen-before laundering patterns with the stolen funds from the Binance exploit,” Chainalysis shared.

North Korea was behind the theft of more than $6 billion in cryptocurrency from Binance, the FBI has confirmed.

The FBI tied the attack to TraderTraitor, the North Korean group it named in the $1.5 billion Bybit hack of February 2025.

By early October 2025, blockchain analytics firm Elliptic had linked more than $2 billion in stolen crypto to North Korea for that year alone, most of it from the Bybit heist, along with more than thirty other hacks.

About $6.3 billion left Binance wallets on October 29, in what is likely the biggest crypto theft in history.

The company has replaced about 95% of the stolen assets with its own money, up from 90% in its previous update.

Deepseek released a research prototype of dsh-superagent, a coding agent that does work on a GitHub repository for you.

Who can ask for workThe agent gets to work in two situations: an allowed user asks for something, or a rule your team wrote covers it.

You can also open up a chat or GitHub scope, and then anyone in it can request work just by mentioning the agent.

Explicit requests, such as an allowed user mentioning the agent, work in every mode.

By default the agent doesn’t turn on auto-merge under its own account, because GitHub credits the merge to whoever enabled it.

In this Help Net Security interview, Vinay Thakker, CTO of KloudStax, explains how to set identity, credentials, and network limits for AI agents.

If you had to write the first ten lines of a command policy for a coding agent with terminal access, what would they say?

Anything that needs one goes through a broker the agent can’t read.

Network access is off except for the internal package mirror and the specific hosts this project needs.

Every command is logged with the agent’s identity and the task that triggered it, and a spend or runtime cap ends the session when it’s hit.

Byoky is an open-source wallet for AI API keys, available as a Chrome and Firefox extension and as iOS and Android apps.

Apps that want those keys ask the wallet for access, and the wallet sends each request to the provider itself.

Byoky goes after the habit of pasting a key into a web app’s settings page to try a new tool.

Byoky copies the model of MetaMask, the crypto wallet that decentralized apps connect to: the app asks, the user approves, and one click revokes access.

The bridge rejects requests that lack a bridge token, a check meant to stop other programs on the same machine from spending the keys.

Trust Onion is a free app that gives trusted groups three rotating codewords to check who they are communicating with.

I tested the iPhone app with an older person, exploring setup and the tools available when a call or message raises concerns.

Get help from my group lets users select trusted contacts and send a callback request with an optional note.

Final thoughtsTrust Onion can help older people pause and check a request when a convincing call creates a sense of emergency.

Practicing with someone they trust can make that pause part of their response, even when they feel pressured to act.

The group behind the Aur0ra ransomware has been using AI agents to move through victim networks, collect credentials and work its way up to domain administrator access, according to Sophos.

In some networks, the agents gained domain management access, and three of those victims were later named on Aur0ra’s data leak site.

A red team cover storyTo get around the guardrails built into the AI tools, the attackers described the intrusions as authorized red team activity or diagnostic testing.

The researchers consider it highly likely that other ransomware groups will build AI agents into their operations too.

A Syrian man who used a hijacked news agency Twitter account to post a fake report of explosions at the White House has been sentenced to 42 months in prison, the US Department of Justice has announced.

The scheme ran from as early as August 2011 until January 2024, and Agha spent more than a decade on the run.

Punishing the pressTo spread the regime’s propaganda, Agha hacked approximately 47 Western media outlets, businesses, NGOs, and US and allied government entities.

Interesting research: “AI Models Can Provably Hide Arbitrary Capabilities”

Abstract: Capability evaluations aim to surface dangerous model behaviors before deployment, but their reliability depends on the assumption that hidden capabilities can be elicited. We show this assumption does not hold under adversarial conditions by constructing backdoor attacks that embed encrypted neural networks within host model weights, decrypting and executing them only upon receiving a secret trigger. Using digital lockers, these hidden circuits remain provably hard to elicit and interpret under cryptographic assumptions, even given full access to model weights, extending prior work from hiding fixed string…

Interesting research:

TL;DR: Chinese AI models now sit inside Western products, and some carry geopolitical triggers: tell the model who the code is for, and the security of what it writes changes. For the first time, we showed that this vulnerability lives in the model’s weights, and that removing the model’s CCP alignment removes it. One word tilts the code against Americans. Ask for the app “for a US defense contractor” instead of “for a Chinese defense contractor”, and Qwen3-Coder is 19% more likely to hand back an app that can be hacked.

The Indian CA eMudhra Limited has eight TLS certificates with laughably weak private keys:

The compromised eMudhra keys were defective at a level that’s challenging the imagination of many of the engineers studying the incident. A normal size for a NIST P-384 elliptic curve cryptography private key contains roughly 384 bits of entropy, a size allowing almost 2384, or a number with 116 digits, different possibilities. The private key sizes of the compromised keys ranged from 3 to 8 bits. Astonishingly, the private keys were 4, 56, 66, 115, 155, 156, 230, 237...

PHP maintainers have released two critical vulnerabilities:

PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35 fix two critical vulnerabilities that can allow unauthenticated remote code execution. All PHP users are strongly encouraged to update immediately. Who is at risk: all PHP installations serving web requests, including PHP-FPM, Apache with mod_php, php-cgi, FrankenPHP and LiteSpeed. We consider the risk highest for mod_php, with a demonstrated exploit where an unauthenticated request can trigger the attack before any application code runs.

Interesting research:

Abstract: Vision-language models (VLMs) can solve visual CAPTCHAs without task-specific training, but the agents built on them approach every challenge from scratch. For such an agent, the hundredth instance of a familiar puzzle costs as much time and compute as the first. Specialized detectors invert the trade-off, answering in milliseconds but only for categories they were trained on. Neither improves with exposure. We study what changes when a solver improves with use. Our system pairs a fine-tuned YOLOv8 detector with an open-weight VLM behind a confidence-based router, and runs entirely from screenshots and operating-system input events, with no browser automation…

This is a problem:

Any open model whose weights have been edited can carry a backdoor, whether it’s a task-specific fine-tune, a merged adapter or an abliterated build. We have abliterated models in the title because it’s the most popular reason people download modified weights without verifying what’s inside. Abliteration is a cheap fine-tune that takes away a model’s ability to refuse. You find the direction in the weights that carries “no” and subtract it. The model then answers things a safety-tuned version would turn down. It began as a research trick and it’s now routine before people upload a model to Hugging Face, where you’ll find abliterated builds of most of the popular open weig…

Matthew Green has a new site that tries to estimate the number of cryptanalyst-hours that have been spent analyzing different public-key algorithms:

These publication-based estimates may substantially overstate actual time spent. Lattices have overtaken elliptic curves in this cumulative measure only r…

Earlier today, PHP released an emergency security update to fix two critical bugs that can allow an attacker to execute code of their choosing on a vulnerable server.

Reuters reports that government websites in Europe and elsewhere went offline today after the PHP vulnerabilities were disclosed.

Wiz said that prior to the PHP bugs being publicly disclosed, the company worked with the PHP team, Calif and OpenAI to measure the size of the problem and coordinate patch verification and disclosure.

The PHP zero-day vulnerabilities are being tracked by their CVE numbers, CVE-2026-109618 and CVE-2026-109619, and they affect all web servers running PHP 5.4 or later.

According to the FBI, ShinyHunters has extorted more than $70 million from victims so far this year.

He also said Mr. Dubrovsky has misrepresented himself as a Cypfer founder, and is not a shareholder.

In 2020, Aon aquired Cytelligence, a security consulting firm where Mr. Tobok was founder and CEO and Mr. Dubrovsky was a managing partner.

Experts say ransomware victims are typically directed by their insurance provider to work with a specific incident response firm.

But that ransom payment did not stop future extortion attempts using the same stolen data.

The sanctions freeze any Cryptomus assets at U.K. banks, and bar British companies from offering it any business, virtual or otherwise.

The blockchain data-crunching firm Chainalysis said the U.K. sanctions target the broader infrastructure supporting Russia’s wartime economy.

“Cryptomus and Heleket have emerged as major payment hubs for illicit activity,” Chainalysis wrote in an October 8 blog post.

Sanders said the U.K. sanctions on Cryptomus are important because Canada’s sanctions against the platform were ultimately unenforceable and uncollectible.

“A fine doesn’t stop a cryptocurrency payment processor from processing payments,” Sanders wrote on LinkedIn.

Microsoft today issued updates to fix more than 1,400 security vulnerabilities in its Windows operating systems and other software.

CVE-2026-96951 is a security feature bypass in the Windows Shell that affects Windows 10 and 11 systems, as well as some Server versions.

Windows 10 users might be wondering if they can still expect security updates after this month.

Microsoft had been slated to stop shipping updates for Windows 10 systems in October 2025, but ended up adding another year of free updates after considerable pushback.

Satnam Narang at Tenable said the number of flaws fixed this month far surpasses the previous record-setting year 2020, when Microsoft patched 1,261 CVEs.

The New York Times reported today that the FBI has arrested a Canadian man in Pennsylvania on suspicion of assisting ShinyHunters.

The Times story did not identify the man, nor did a statement on Twitter/X about the arrest from FBI Director Kash Patel.

Another shared that control over the ShinyHunters investigation has been centralized at an FBI field office in Texas.

According to LinkedIn, Cypher was co-founded by a Canadian man named Edward Dubrovsky, who is now associated with another Canadian security firm called CyberSteward.

According to the FBI, the group has extorted more than $70 million from victims so far this year.

The Dutch daily RTL reported on Sept. 29 that investigators suspect Van der Stap tried to orchestrate at least two murders.

According to RTL, the murders were allegedly to be committed abroad, and there are indications Van der Stap gave the order for these attacks.

In an interview with KrebsOnSecurity on September 9, Van der Stap described his new role as “offensive security lead” at the Dutch cybersecurity company Neo Security, saying the job involved probing client networks for security vulnerabilities.

Korper said Dutch forensic investigators visited his office on September 15, the night Van der ⁠Stap was arrested in a dramatic police raid that reportedly involved flash bang grenades.

Authorities in the Netherlands have arrested a 23-year-old convicted cybercriminal on suspicion of aiding in data thefts and extortions by the prolific hacker group ShinyHunters.

Van der Stap is currently employed as offensive security lead at the Dutch company Neo Security, which did not respond to requests for comment.

But not long after that interview, the Dutch hacker abruptly stopped replying to messages.

One source said a colleague of theirs personally witnessed Dutch authorities carting items out of Van der Stap’s residence.

Speaking with reporters from Bloomberg in 2024, Van der Stap said that singular focus in turn fueled his desire to carry out cyberattacks.

A U.S. Army soldier who pleaded guilty to hacking into multiple telecommunications companies and stealing mobile call and text metadata for more than 100 million AT&T customers in 2024 was sentenced to 70 months in federal prison today and ordered to pay nearly $300,000 in restitution to victims.

Kiberphant0m claimed to have hacked into more than dozen telecommunications companies worldwide, including Verizon’s Push-to-Talk business, and publicly extorted these companies in exchange for a promise not to publish the stolen data.

Less than a month later, Wagenius was arrested and charged in two separate federal indictments, and soon pleaded guilty to all counts in both cases.

Microsoft Corp. today issued updates to plug at least 974 security holes in its Windows operating systems and other software, by far its biggest single patch batch ever.

This month’s patch bundle obliterates the software giant’s previous record set in July, when it released updates for at least 570 security vulnerabilities.

Among the more serious critical flaws this month is CVE-2026-69730, a DNS weakness present in Windows Server 2012 onward and on Windows 10.

And at the rate these Windows patch releases are ballooning in size, it’s probably best not to let them pile up month after month.

A new identity theft service launched on the dark web this week is selling digital scans of more than 153 million drivers licenses from people in the United States and Canada.

Curiously, the identity records include not only drivers licenses but also marijuana dispensary cards.

Some of the records list their “source” as “CDL,” presumably short for “commercial drivers license.

Also, only some of those who helped with this research said they showed their drivers license at the airport on the day of their travel.

Baldwin said the Nexus identity theft service presents multiple serious security and privacy threats, noting that state-issued drivers licenses are commonly used as proof of one’s ide…

The malware allows TeamPCP’s hackers to steal credentials that let them publish malicious versions of those software development tools, too.

Microsoft today released updates to remedy at least 398 security vulnerabilities in its Windows operating systems and supported software, including one weakness that is already being actively exploited and two others that were publicly detailed prior to today.

August’s overstuffed bundle of patch joy from Microsoft did not eclipse its recording breaking release of more than 570 security updates last month, but it is double June’s then-record batch of nearly 200 fixes.

The other publicly disclosed flaw is CVE-2026-72971, a low-impact local tampering vulnerability that Microsoft reckons is unlikely to be exploited.

By all accounts, AI is quite good at finding security holes in software.

Snowflake responded to the data thefts by increasing password complexity requirements and enforcing multi-factor authentication.

A little more than a month later, Canadian authorities arrested Moucka on a provisional warrant from the United States.

“Moucka used the stolen data of a government officer and members of a then-former government officer’s immediate family in this re-extortion attempt,” reads a statement from the Justice Department.

Moucka pleaded guilty to four criminal counts, including computer fraud, wire fraud, aggravated identity theft, and conspiracy.

Ultimately, it will be up the federal judge how much time Moucka actually serves for his extensive cybercriminal rap sheet.

Ambulances were diverted, surgeries cancelled, and medical students sent home from classes after a ransomware group attacked the University of New Mexico's Health Sciences Center (HSC) this week. Read more in my article on the Fortra blog.

You are suffering a little bit, not that our listeners will be able to tell, but if anyone sees you on video.

Well, everything's a little bit political, but this is fundamentally a cybersecurity podcast.

And it won't necessarily come back and say, "I don't think you should be doing this," or, "Have you sought some help?"

Maybe we should turn a little bit to what organisations can actually do about it.

I'm going to do it the following Thursday, or I'm going to do it some other time, or I'm going to create an account that doesn't go back to me, but I can still support my favourite places.

A Ukrainian man has been sentenced to 70 months in a US prison for his role in a series of ransomware attacks.

He was also an early affiliate of the Hive ransomware-as-a-service (RaaS) operation which targeted businesses and, in particular, organisations working in healthcare.

The FBI later warned that Hive had extorted US $100 million from businesses and organisations globally in a period of just 18 months.

The DOJ said that the operation saved corporate victims of Hive over US $130 million in ransom payments.

At the time I speculated that the take-down of Hive may lead to the identification and possible apprehension of some of those involved in Hive ransomware attacks.

Germany's far-right AfD (Alternative für Deutschland) party has confirmed that it has suffered a security breach, after a hacker published what appear to be hundreds of thousands of the controversial political party's internal emails.

Earlier this week, the AfD admitted that its hosting provider had been hacked in September, and that some of its mailboxes had been copied.

What is unusual is that the leaked emails are not published on the site directly.

Indeed, party sources told the media that although the leaked emails appeared to be authentic, the AI-generated summaries appeared to contain several inaccuracies.

The full corpus of 281 GB of stolen messages and files has been made available…

Smashing Security, episode 489, How a Brand New Crypto Wallet Came with a Spy Inside, with Graham Cluley and special guest Lianne Potter.

So a bit of a War of the Roses thing going on there with that reference to Burnham.

What I'm going to do is I'm going to describe things, and the more dangerous the thing is, the faster it will click.

But I'm going to say it's probably dodgy, but oh, the curiosity would get the better of me.

But I'm actually in the same boat as most people because this film has been censored for nearly half a century.

A 28-year-old Russian man has been arrested by German police, suspected of being a key member of the Qilin ransomware gang.

As BBC News reports, detectives have linked the man to the 2024 attack against blood-testing firm Synnovis, that disrupted London hospitals, and resulted in the death of a patient.

The suspect, who has been named by German media only as "Vladimir K" was originally detained in May in Japan, after he travelled there on holiday.

The incident is said to have crippled Synnovis’s IT systems, and caused a critical shortage of O-type blood in hospitals.

No ransom was paid by Synnovis, a decision the firm made jointly with the NHS trusts to which it provides services.

The official @GardaInfo and @GardaTraffic Twitter accounts of Garda Síochána were accessed by an unauthorised third party who posted cryptocurrency-related messages on Wednesday evening, potentially reaching hundreds of thousands of users.

The messages claimed that followers were eligible to claim free cryptocurrency through an airdrop.

The problem, however, is not just that a hacker found themselves with the ability to post fraudulent messages posing as the Irish police.

The Garda is not the only police force to have ever suffered a security breach on its Twitter account.

In 2022, the official Twitter account of the Philadelphia Police Department was compromised and used to post what appea…

How a ransomware negotiator ended up arrested at his own conference, with Graham Cluley and special guest Paul Ducklin.

I don't know if you know that.

And then I became a freelancer and then I thought, oh boy, I'm going to open the doors to everybody.

And he is the Canadian co-founder of a ransomware negotiator firm called— I don't know how to pronounce this.

There's no breach so unimportant that you can just say, don't worry folks, carry on, nothing to see here.

The hacker behind a high-profile string of leaks involving the upcoming release of the Grand Theft Auto (GTA) 6 videogame has threatened to release a complete, playable build.

CyberLeek says that if the GTA 6 game is released on physical disk, and a public apology is made, it will step back from its threats.

As ever, videogame fans should be very wary of believing anybody who offers a download of a supposedly leaked game.

Besides which, the real, genuine GTA 6 is due to be released on video game platforms on 19 November.

It is not worth infecting your computer, or losing money on a dodgy crypto coin, just to see it a few weeks early.

Zhang is charged alongside 34-year-old Xu Zewei with malicious cyber activity against US computer systems between February 2020 and June 2021.

The following the year the pair allegedly exploited vulnerabilities in Microsoft Exchange Server to steal further information.

Furthermore, if findings by security firm SentinelOne are to be believed, Zhang's Shanghai Firetech filed multiple software patents about extract data from computers.

Xu, for instance, was arrested at Milan airport in July 2025 and extradited to the United States in April this year.

China's Foreign Ministry opposed Xu's extradition, accusing the United States of fabricating charges against him.

But do you actually know whether both of them can do the job?

Now, I don't know how good a swimmer you are, Danny.

I don't know about you, but I'm having 3 or 4 calls a day from an unknown number.

And I would imagine a company like Hack The Box has got great visibility as to what is actually going on out there.

And so I think that's the unique part here is it truly does have a pressure-tested element to it.

N0n is a newly-emerged cyber extortion gang. The group was first spotted in the middle of September 2026, and within days it had published on its dark web leak site details of what it claimed to be around a dozen victims. Since then, the tally has continued to grow. Read more in my article on the Fortra blog.

The FBI has a very simple message for the ShinyHunters gang: give yourselves up.

The FBI describes the man arrested in Amsterdam as "one of the alleged leaders of ShinyHunters", although Dutch police say only that he played a role.

The warning to remaining members of ShinyHunters follows particularly embarrassing episode for the FBI, which recently confirmed it had had its job application portal compromised by the gang.

According to ShinyHunters, it gained access to the FBI's data by exploiting a recently-patched flaw (CVE-2026-35273) in Oracle PeopleSoft PeopleTools.

The truth is that the arrest came a week or so before the compromise of the FBI became headline news.

Вопреки распространенному заблуждению, в эпоху цифры люди не перестали любить книги — просто их уже давно читают не только на бумаге.

Год назад мы также рассказывали про вредоносные «книги» на турецком и арабском языках.

Зачастую эти поддельные сайты полностью функциональны: на них точно так же можно искать и скачивать книги, и дизайн практически неотличим от оригинала.

Одна из самых простых рекомендаций — пользоваться официальными книжными магазинами, и не только по соображениям авторских прав.

Таким образом вы защитите свои данные и деньги и сможете спокойно скачивать и читать вашу любимую литературу.

The velocity of vulnerabilities being discovered using Frontier AI and OpenWeight models such as Cisco Anteras is unprecedented and defenders need more time.

Virtual Patching vs. Live Protect (Shielding)Live Protect is a differentiating capability – we are not built the same.

The workload in the environment still sits vulnerable and that’s where Secure Workload can be expanded to drive controls based on CVE directly in the workload using native capabilities and once patched the control disappears.

Shielding with Live ProtectShielding with Live Protect is different.

Live Protect buys you time on the infrastructure boxes themselves without forcing an emergency upgrade window.

Infrastructure access has an identity problemPicture an infrastructure administrator pushing a configuration update across hundreds of switches during a maintenance window.

Introducing Cisco Privileged Infrastructure AccessToday, Cisco is introducing Privileged Infrastructure Access, a faster, more secure way to keep the network moving by enabling network administrators and agents to perform critical work through a secure, identity-bound connection.

For customers using Cisco ISE and TACACS+, Privileged Infrastructure Access can draw on the policy and device context they already manage to govern access to Cisco routers and switches.

That brings Cisco network context into the privileged acces…

The data bears this out: in Splunk’s State of Security 2025 report, 78% of respondents said their security tools are dispersed and disconnected.

Closing that gap takes integrated identity, network, and endpoint context, plus the ability to act on it automatically.

That’s the idea behind combining SentinelOne’s runtime protection with Cisco Security and Splunk.

SentinelOne Runtime Protection and CWP in ActionSentinelOne Cloud Workload Protection (CWP) delivers autonomous, real-time threat detection and response across containers, Kubernetes, virtual machines, and serverless workloads.

Cisco Security extends that protection across identity, network, and perimeter, and Splunk gives your SOC on…

Upstream capacity: the projects you depend on can deliver new capabilities and critical fixes fast.

Upstream capacity is the one almost nobody puts on a roadmap because it sits outside your organization.

In most organizations, upstream capacity has none of those.

What This Looks Like in PracticeFor Cisco, part of the answer was becoming a Premier Sponsor of the OpenSSL Foundation in August 2025.

Tomáš Mráz, CTO of the OpenSSL Foundation, describes the impact:“Cisco’s support for the OpenSSL Foundation allowed us to fund an additional senior software engineer to improve the OpenSSL Library code.

CSDL continues, and does moreThe Cisco Secure Development Lifecycle (CSDL) is built on more than 400 software security requirements that validate products before they are released, with engagements at key stages of development.

Cisco open-sourced it and donated it to the Coalition for Secure AI (CoSAI).

Our secure software guidance skill is in development, carrying Cisco-specific security requirements into the development workflow.

Project CodeGuard and the secure software guidance skill also act as evaluators in the development pipeline, backing hard gates.

To date we have not found a novel issue that was not already covered by an existing software security requirement.

The Splunk .conf network brought a new detection that we hadn’t seen before: Flawed AMMYY.

There is also a Remote Access Tool (RAT) called Flawed AMMYY that was developed from leaked AMMYY source code, and is directly used as malware.

One of the key value propositions of EVE is that it can use granular session fingerprinting to differentiate between similar but distinct applications like AMMYY and Flawed AMMYY.

Let’s dig into the events we saw for Flawed AMMYY and some of the details that EVE had to look at.

Our EVE detections for Flawed AMMYY came in pairs with identical timestamps, as seen above, all from a single IP.

The event Network Operations Center (NOC) managed the venue network, providing our SOC firewalls with dedicated SPAN feeds directly from their core switches.

Inside Cisco Cloud Control, that story comes together in Unified Events.

While Splunk drives active investigations in the SOC, administrators maintain firewall health directly within Cloud Control.

The Horizon: Cisco Cloud Control & AI CanvasSecurity is now natively built into Cisco Cloud Control, the unified operations platform that brings Networking, Security, Observability, and Cloud into one consistent environment.

Without replacing individual product controllers, Cisco Cloud Control unifies inventory, topology, actions, identity, …

However, assessing whether a zero-day vulnerability was exploited in the past essentially involves going back in time.

Relying on standard logs or “Conditional / Selective PCAP” systems during a zero-day investigation leaves the Security Operations Center (SOC) team blind.

There is also a secondary benefit: if a breach occurred using an newly disclosed zero-day vulnerability, the attacker is likely to have been very sophisticated.

Here, threat actors may simply seed prompt injections on websites in hope of corrupting AI systems that browse them.

Early experiments revealed a significant volume of "benign" prompt injection text, which illustrates the complexity of distinguishing between functional threats and harmless content.

Many prompt injections were found in research papers, educational blog posts, or security articles discussing this very topic.

(Source: GitHub/swisskyrepo)When searching for prompt injections naively, the majority of detections are benign content – false positives in our case.

Hook-up Rust to modem firmwareBefore building the Rust DNS library, we defined several Rust unit tests to cover basic arithmetic, dynamic allocations, and FFI to verify the integration of Rust with the existing modem firmware code base.

Pixel modem firmware already has a well-tested and specialized global memory allocation system to…

This project represents a significant step forward in our ongoing efforts to combat session theft, which remains a prevalent threat in the modern security landscape.

Session theft typically occurs when a user inadvertently downloads malware onto their device.

Once active, the malware can silently extract existing session cookies from the browser or wait for the user to log in to new accounts, before exfiltrating these tokens to an attacker-controlled server.

How DBSC WorksDBSC protects against session theft by cryptographically binding authentication sessions to a specific device.

The issuance of new short-lived session cookies is contingent upon Chrome proving possession of the correspondi…

Staying ahead of the latest indirect prompt injection attacks is critical to our mission of securing Workspace with Gemini.

In our previous blog “Mitigating prompt injection attacks with a layered defense strategy”, we reviewed the layered architecture of our IPI defenses.

Synthetic data generationAfter we discover, curate, and catalog new attacks, we use Simula to generate synthetic data expanding these new attacks.

We partition the synthetic data described above into separate training and validation sets to ensure performance is evaluated against held-out examples.

This process leverages the newly generated synthetic attack data described on this blog, to create a robust, end-to-end evalu…

Today we're announcing a new program in Chrome to make HTTPS certificates secure against quantum computers.

Instead, Chrome, in collaboration with other partners, is developing an evolution of HTTPS certificates based on Merkle Tree Certificates (MTCs), currently in development in the PLANTS working group.

Since MTC technology shares significant architectural similarities with CT, these operators are uniquely qualified to ensure MTCs are able to get off the ground quickly and successfully.

The Chrome Quantum-resistant Root Program will operate alongside our existing Chrome Root Program to ensure a risk-managed transition that maintains the highest levels of security for all users.

First, we…
