Опыт применения R-Vision SOAR на Standoff 17 показал, какие задачи помогает решать на практике автоматизация.

Именно в таких условиях на юбилейном Standoff 17 решение R-Vision SOAR использовалось командой защиты ретейла.

Standoff — это практическая кибербитва, в рамках которой команды атакующих и защитников проверяют сценарии нападения и реагирования в квазиреальных инфраструктурах.

Как SOAR применялся на StandoffВ 2025 году для работы R-Vision SOAR на Standoff было настроено более 40 коннекторов с различными средствами защиты и инфраструктурными системами.

Таким образом, участие R-Vision SOAR в Standoff стало практической проверкой работы интеграций, удобства выполнения типовых действий и …

Переход с Microsoft Office на альтернативные офисные пакеты — это не только установка нового ПО, но и риск столкнуться с несовместимостью документов, макросов и шаблонов.

Такие проблемы массово возникали при обновлении с Microsoft Office 7/95 на Microsoft Office 97.

А именно так обстоит дело в «МойОфис» и «Р7-Офис» (как и в его основе с открытым кодом OnlyOffice).

В Microsoft Office для создания формул применяется шрифт Cambria Math, и при подстановке его аналога для других платформ всё должно нормализоваться.

Наиболее часто проблема проявляется в Linux, но нередко имеет место и в Windows, и в Android.

Значит ли это, что обучение не работает, или проблема в самом подходе к нему?

Выделили шесть возможных причин, по которым обучение ИБ не работает так, как ожидается.

Как понять, что обучение не даёт результатыМожно выделить следующие критерии неэффективного обучения:Сотрудник регулярно совершает одни и те же ошибки.

Такие ситуации возникают потому, что знания не были связаны с реальными рабочими процессами и не стали частью повседневных действий.

ВыводыПричины, по которым обучение информационной безопасности не работает, имеют не методический, а организационный характер.

KPI, KRI и метрики: в чём разницаПри обсуждении информационной безопасности термины KPI и KRI часто путают, хотя они решают разные задачи.

При этом и KPI, и KRI рассчитываются на основе технических и бизнес-метрик, которые собирают системы мониторинга, средства защиты и другие источники данных.

Этот показатель отражает период от компрометации до обнаружения злоумышленника и не является MTTD, однако показывает, сколько времени атакующий может оставаться незамеченным.

Уровень проникновения ИИ в российских компаниях по ряду отраслейОднако внедрение ИИ далеко не всегда было экономически оправданным.

Влияло и то, что в ряде отраслей, в частности в медицине, это прямо сказывалось на показателях эффективности руководителей учреждений и глав региональных министерств здравоохранения.

Предав наследие наших предков, мы встали на путь саморазрушения — морального, интеллектуального, экономического и, в конечном итоге, биологического.

Но что реально происходит «под капотом» и в какую сторону склонится чаша весов «независимости» — для большинства стран это риски ИБ.

Выход из них далеко не всегда способствует достижению общих целей — технологического и инновационного развития с соблюдением регуляторных и конституционных требований.

Но чтобы понять CORS, надо сперва как следует понять само правило, потому что почти вся путаница вокруг CORS растёт из того, что Same-Origin Policy поняли неточно.

Отсюда прямое следствие: если ваше API отдаёт что-то, что не должно попадать посторонним, CORS не защитит это ни на секунду.

«Заблокировано по CORS» не равно «не выполнилось» — выполниться оно вполне могло, вы просто не увидели результат.

Где на CORS обжигаютсяПоскольку CORS настраивают руками, а его логика неочевидна, ошибок вокруг него хватает, и часть из них превращается в полноценные дыры.

Как только в голове щёлкает это разделение, вся многолетняя путаница вокруг SOP и CORS растворяется без остатка.

Многие представляют IT‑безопасников суровыми дядьками без чувства юмора и с нулевой терпимостью к окружающим.

Ведь это я на утренней пятиминутке полтора часа объясняю всему коллективу, почему нельзя хранить эксель‑файл с названием «клиентские_пароли» на рабочем столе.

В IT слово «тестовый» часто означает: «Мы надеемся, что это не попадёт в публичный доступ, как в прошлый раз».

Я как глютен: никто точно не знает, что я делаю, но все убеждены, что без меня было бы лучше.

Иногда мне кажется, что в этом и заключается моя работа — ходить и говорить: «Так делать нельзя».

В этой статье разберём на примерах, как делать неправильно и как, по моему мнению, стоит делать правильно.

Такое закладывается изначально как дыра, а не как недоработка, которую можно поправить позже.

ЗаключениеЕсли подытожить: идеальный enterprise — это не про красивые слова в лицензии, а про то, что архитектура физически не даёт себя обмануть.

Спецификация HTTP/1.1 оставила два разных механизма, которыми можно указать длину тела запроса, и они совершенно легитимны оба.

Если написано Content-Length: 11 , значит после заголовков и пустой строки идёт ровно одиннадцать байт тела, и на этом запрос кончается.

TE.TE: когда оба умеют chunked, но одного можно обманутьТретий вариант, TE.TE , возникает, когда и фронтенд, и бэкенд в принципе умеют обрабатывать Transfer-Encoding .

В логах RDP-подключений иногда встречается запись, которая выглядит как ::%16777216 — и это вместо привычного IP-адреса.

Причем в исходном XML-представлении события значение выглядит точно так же, так что это не проблема форматирования.

Я подключился по RDP через этот туннель и увидел в логе то, что и ожидал, — то самое значение ::%16777216 .

Утилита перехватывает API-вызовы и показывает, что попало на вход и что вернулось на выходе.

Я провел еще один эксперимент: вместо адреса ::1 взял нормальный IPv6-адрес, подключился по RDP напрямую, без туннеля, и посмотрел на результат в логах и в памяти.

Применяется и на старте, когда мы еще ничего не знаем о сети, и перед аудитным сканированием, чтобы ускорить процесс и не долбиться в мертвые адреса.

Забытый тестовый сервер, принесенный подрядчиком коммутатор, поднятая мимо процессов виртуалка - все это находит Host Discovery и сетевое сканирование, а не агент.

Хотя за глубину данных придется поторговаться - EDR собирает то, что нужно ему, а не то, что нужно расчету уязвимостей.

Снимок - это состояние диска, а не работающей системы: что происходит в памяти, какие соединения установлены, что творится в контейнере прямо сейчас, по нему не увидеть.

Версию ПО он определит по косвенным признакам, а не по списку установленных пакетов.

Вот он целиком, как лежит в JSON:Первое, что бросается в глаза: поле thinking пустое.

Не в том смысле, что модель не думала.

Я потратил пять минут, чтобы понять, что это, и слегка похолодел: это oauthAccount.organizationUuid из моего же ~/.claude.json .

То есть каждый зашифрованный блок рассуждений таскает внутри заголовка, открытым текстом, id модели и id вашей организации.

Всё это едет в каждом коммите, где вы случайно оставили .jsonl историю агента, и в каждом датасете агентских логов, выложенном на Hugging Face.

Старшую модель при этом не взламывают вообще: ее защиты от дистилляции просто не срабатывают, потому что к ней никто не обращался.

Провайдеры фильтруют то, что модель говорит вслух, но не то, что она думает по дороге к ответу.

Сервер провайдера послушно расшифрует блок, и модель прочитает чужую инструкцию как собственное прошлое рассуждение, а не как подозрительный текст со стороны.

Тема верности цепочек рассуждений обсуждается не первый год, но в случае закрытых API сравнивать саммари до сих пор было не с чем.

И не полагаться на то, что раз вы сами не можете это прочитать, то и никто не сможет.

На практике это означает, что все те практики, которые DevOps-инженер считает базовыми — версионирование, CI/CD, контейнеризация, мониторинг, секреты — распространяются ещё и на данные и модели.

Для этого нужен трекинг экспериментов — мы взяли MLflow с PostgreSQL в качестве бэкенда.

Архитектура: что и зачем мы развернулиПлатформа спроектирована для работы в закрытом контуре: приватный GitLab, приватный Docker Registry, внутренний Ingress, никаких облачных сервисов.

Мы использовали это, когда понадобилось передать MLFLOW_TRACKING_USERNAME и MLFLOW_TRACKING_PASSWORD в singleuser-поды JupyterLab из того же секрета, что используется для MLflow и inference.

Исследователи Tencent обнаружили в сетевом коде Linux уязвимость типа use-after-free, которая присутствовала в ядре с 2008 года.

В результате SCTP-соединение продолжает ссылаться на освобожденную память, что и приводит к возникновению use-after-free.

SCTPhantom присутствует в коде Linux начиная с версии 2.6.25, вышедшей в 2008 году, однако серьезность проблемы снижается в силу того, что для эксплуатации CVE-2026-64564 требуется локальный доступ, а SCTP должен быть доступен в целевой системе.

Однако исследователи пишут, что успешно получили root-права в Debian 13, Ubuntu 24.04, Rocky Linux 9, RHEL 9 и OpenCloudOS.

Однако позже исследователи нашли способ активировать нужные возможности SCTP н…

Авиакомпания Delta расследует инцидент, произошедший на борту рейса 591, который следовал из Лас-Вегаса в Атланту: в самолете была обнаружена посторонняя сеть Wi-Fi под названием Delta WiFi Fast.

Так как рейс перевозил в том числе участников завершившейся накануне конференции DEF CON 34, члены экипажа заподозрили, что кто-то из пассажиров пытается провести кибератаку.

Инцидент произошел на борту Boeing 757, где находились 199 пассажиров и шесть членов экипажа.

После обнаружения подозрительной активности экипаж примерно на 30 минут отключил Wi-Fi на борту.

Повторное обновление потребовалось из-за продолжающихся атак на уязвимость CVE-2026-18577: злоумышленники получают права администратора на серверах N-central и проникают в системы клиентов.

Тогда расследование показало, что неизвестные атакующие эксплуатировали 0-day-уязвимость в N-central, которая в итоге получила идентификатор CVE-2026-18577 (8,2 балла по шкале CVSS).

Однако спустя несколько дней в N-able подготовили второй срочный патч, вошедший в версию 2026.3.1.10.

Как выяснилось, получив административный доступ к N-central через 0-day-баг, злоумышленники использовали штатную функцию Take Control для подключения к компьютерам внутри управляемых окружений.

По данным двух крупных ретейлеров, продажи увеличились более чем вдвое.

В «М.Видео» сообщили, что число проданных кошельков во втором квартале выросло на 107% по сравнению с первым, а продажи в денежном выражении увеличились на 92%.

Продажи в денежном выражении увеличились на 60%.

При этом средняя цена аппаратного кошелька на Wildberries снизилась на 13% — до 7900 рублей, а в «М.Видео» расширили ассортимент таких устройств.

Продажи кошельков также растут незадолго до вступления в силу более широкого режима регулирования криптовалют в России, намеченного на 1 сентября.

Злоумышленники публикуют в русскоязычном Telegram-канале модифицированные версии популярных приложений и предлагают пользователям установить их в обход App Store.

В некоторые приложения встроен вредоносный модуль, который собирает данные об устройстве, отслеживает геолокацию и делает снимки экрана.

По информации специалистов «Лаборатории Касперского», атакующие модифицируют настоящие приложения, внедряя в них малварь.

Так, среди обнаруженных зараженных образцов были модифицированные версии неназванных приложений онлайн-площадки для продажи товаров, фоторедактора и сервиса для просмотра видео.

A newly disclosed flaw in the way OpenAI, Anthropic, and Google carried hidden AI reasoning between API calls let researchers recover internal reasoning and secrets from session logs, including API keys and passwords.

Developers are advised to strip reasoning blocks and opaque reasoning fields from shared traces and avoid committing raw API transcripts even when the visible text has been sanitized.

OpenAI can return encrypted reasoning items that applications replay with manually managed history, Anthropic carries full reasoning in an encrypted signature, and Google uses encrypted thought signatures.

Current vendor documentation shows that encrypted reasoning remains part of these APIs, but…

The perimeter now blocks roughly two attacks out of three; inside, defenses stop barely one in three.

Here too, noisy actions get caught, while quiet ones don’t.

Adobe has shipped updates to address multiple critical security vulnerabilities impacting ColdFusion, Commerce, and Campaign Classic that, if successfully exploited, could result in arbitrary code execution and privilege escalation.

It's worth noting that the Campaign Classic updates only apply to fully on-premise deployments and to the on-premise components of hybrid deployments.

A remote flaw reachable through the service's TFTP handling without authentication or user interaction.

A remote, unauthenticated code execution flaw requiring no user interaction.

Cybersecurity researchers have discovered a new version of the Kimwolf/AISURU Android and Internet of Things (IoT) botnet that comes with significant improvements to improve its operational resilience and conduct distributed denial-of-service (DDoS) attacks.

"Kimwolf v7 adds an HTTP/2-based DDoS flood that constructs complete browser fingerprints," researchers Asher Davila, Chris Navarrete, and Doel Santos said.

"This makes attack traffic more difficult to distinguish from legitimate browsing."

Kimwolf is known to target Android TV boxes since August 2025, while its Linux counterpart, AISURU, primarily focuses on Linux IoT devices.

Once launched, the malware attempts to mask itself as seemi…

Client fixes shipped in June and July, roughly two months before the flaws were made public, and no exploitation has been reported as of publication.

Zoom tracks the flaws as CVE-2026-53413 (CVSS score: 8.3), a buffer over-write, and CVE-2026-53414 (CVSS score: 6.5), a buffer over-read, both covered by ZSB-26015 and ZSB-26016, plus CVE-2026-53415 (CVSS score: 8.3), a use-after-free, in ZSB-26017.

Zoom issues its own CVE records, and NIST no longer routinely re-scores them, so the lower figures will likely stand.

The advisory says the same bug may let a participant "conduct a denial of service," and scores its confidentiality impact at none.

Security researchers found a way to enter Microsoft SharePoint servers as any user, including an administrator, with no valid account.

The flaw, tracked as CVE-2026-55040 (CVSS 9.1), affects SharePoint Server Subscription Edition, SharePoint Server 2019, and SharePoint Server 2016.

Rapid7 then chained the bypass to a separate remote code execution flaw and ran code on the server with no credentials.

Microsoft shipped the July fix in three server updates:Subscription Edition KB5002882, build 16.0.19725.20434SharePoint Server 2019 KB5002883, build 16.0.10417.20175SharePoint Server 2016 KB5002891, build 16.0.5561.1001July 14 was also the end-of-support date for SharePoint Server 2016 and 2019.…

A view of the H1 2026 threat landscape as seen by ESET telemetry and from the perspective of ESET threat detection and research experts.

The first half of 2026 shows how attackers continue to improve the efficiency and scalability of their operations.

In H1 2026, ESET analyzed nearly 900,000 AI skills – small functional components used by AI agents – and identified tens of thousands of suspicious and thousands of outright malicious instances.

ESET detections of this vector more than doubled between H2 2025 and H1 2026, indicating sustained activity and adaptation.

ESET Research has documented over 100 EDR killers used in the wild, with new variants appearing regularly.

Organizations are right to pay attention, especially because malicious use of AI makes old gaps a more urgent test of an organization’s cyber readiness.

AI and the basics“AI-powered malware” is cited as the top concern of global SMBs for the year ahead, according to the ESET SMB Cyber Readiness Index 2026.

With access to your email account, they can reset your passwords across multiple other accounts – perhaps intercepting one-time passcodes sent by your bank, social media, cloud storage or other online provider.

That could lay the groundwork for a convincing phishing email designed to impersonate a trusted organization you interact with.

A phishing attack on your corporate email account is often the first stage in a bigger data breach, extortion/ransomware or espionage attack.

They’re also using more sophisticated tools to improve the success rates of email phishing campaigns.

In this instance the scammers reportedly hijacked the email account of a high-level executive, before impersonating …

For these businesses, cyber resilience should be the direction of travel – that is, the ability to continue operating and recover even during a serious incident.

Cyber readiness is about putting in place the processes and controls to prevent, detect and respond to threats.

So, should confidence in cyber resilience posture be so high, especially if organizations are still getting hit multiple times?

The truth is that there’s no end state for cyber readiness or resilience.

If it’s serious about improving the cyber readiness of small businesses, the vendor community should step up.

Key points of this blogpost: Throughout 2025, Gamaredon exclusively targeted governmental and military institutions in Ukraine.

Continued data exfiltration and a new allianceThroughout 2025, Gamaredon stayed highly active and remained focused solely on Ukraine.

Notably, we uncovered that in early 2025, Gamaredon collaborated with Turla, another Russia-aligned threat actor also linked to the FSB; we documented our findings in our blogpost Gamaredon X Turla collab.

Of course, connecting production systems to enterprise networks delivers tangible benefits, but the security implications – that systems once safe were suddenly no longer so – arrived more quietly.

Start by mapping which systems in an environment are connected and have no security coverage, where IT and OT networks intersect, which segments are unmonitored, and which production systems have fallen outside any vendor support agreement.

Meanwhile, off-the-peg security tools often don’t efficiently meet the enterprise requirements in legacy OT systems that run on older hardware and outdated operating system versions.

The production systems running that version continue to operate for years, ac…

Instead, attackers get the victim to complete a legitimate authentication process – including two-factor authentication (2FA) – on a real Microsoft login page.

What makes EvilTokens dangerousThe OAuth device code flow was designed for devices that may be awkward to sign into directly, such as smart TVs or printers.

No document, invoice, email, or another platform should ask for a device code without a clear reason.

A real Microsoft page doesn’t automatically make a request safe.

Sometimes the attacker could ask them to enter a real code on a real page – but for the wrong device.

Spanish police have arrested a man in Murcia accused of using deepfake software to trick a certificate provider’s video identity checks in an attempt to obtain digital signatures he could use for financial fraud.

According to the police, the man made 38 attempts using this method on more than 30 citizens.

The National Police said the investigation started after a company that issues electronic certificates flagged a string of suspicious verification requests.

The fraudster ran out of luck when the digital mask glitched for a moment during a live verification call, exposing his true face on screen.

He faces charges over a continuing offense of falsifying official documents.

He explains where post-quantum key sizes break old size assumptions in IPsec, SSH, TLS and libp2p, why migrating user keys makes blockchains hard to upgrade, and what a silent quantum break would look like from outside.

Usually we find that security teams know where the bodies are buried in their own backyard, so to speak.

Libp2p, a widely used peer-to-peer networking library, had several such assumptions that had to be updated when we moved it to post-quantum primitives.

Most blockchains have some form of account abstraction that makes the technical part of the upgrade easier, but migrating user keys is much harder, because it requires every user to act.

They had evaluated the quantum thre…

PentestGPT is an open-source penetration testing agent that points a large language model at a target and lets it work.

In its default mode it runs recon, then exploit, then walkthrough, each stage feeding the next.

The agent drives Claude Code or Codex, runs the tools, and decides what to try next.

Codex login cannot be pre-seeded, because ChatGPT refresh tokens are single-use, so the OAuth callback gets forwarded through socat instead.

A seller on a cybercrime forum is offering a ready-made scam kit for $500, complete with an admin panel that tracks victims, checks their crypto wallets for value, and inflates fake balances to squeeze out more money, Malwarebytes found.

The form that opens up asks for a 12-word recovery phrase, the words that control everything in a wallet.

Instead, the scammer simply receives the cryptocurrency while the victim sees a fake balance displayed on the website,” researchers noted.

The operator can raise it whenever they want, so the investment looks like it’s paying off and the victim sends more.

The panel also lets the scammer manage fake purchase orders and message victims directly.

AI Genie in the WildWhen I give talks about AI genies, I use this sort of example as a hypothetical.

Someone named Andrew tasked OpenClaw to book gym classes for him.

Minutes later, his AI agent reported it had discovered a way to book Andrew into classes several weeks in advance, far beyond what was supposed to be possible.

Andrew, who was sitting fourth on a waitlist for a class later that week, asked if it was possible to move him to the top of the list.

The agent came back and told Andrew that it had kicked another gym-goer off the list as part of the testing of its capabilities.

Interesting empirical research: “Black Box Warfare: Human Judgment and Military Decision-Making in the Age of AI.”Abstract: How is AI transforming decision-making in modern conflict?

This study provides a unique empirical window into that question by deploying a high-fidelity replica of an AI decision-support system (DSS) used in military targeting.

Contrary to widespread fears of automation bias, we find strong evidence of algorithmic aversion, especially in scenarios involving high collateral damage.

Yet we also show that integrating “explainable AI” features reduces algorithmic aversion and promotes more thoughtful evaluations of algorithmic recommendations.

There are many companies manufacturing adversarial clothing designed to confuse facial recognition systems.

It’s a cool idea, but I worry that it’s mostly security theater:“Our patterns play with that chaos, confuse algorithms and make it way harder to pin you down,” he said.

Bell, however, said “none of these products are tried and tested, and a lot of these surveillance technologies can deal with a little resistance … [but] even if the designs don’t necessarily work perfectly, fashion is also a visible sign of resistance.

“This is consumers collectively coming together to make a visible statement.”

This is disturbing:…a team of security researchers at UC San Diego, who found that a model of aftermarket car alarm known as the KARR Security System, installed in more than 2 million vehicles across the US by their estimate, can let any hacker within Bluetooth range send radio commands to silently unlock the car at will, turn off its alarm, honk the car’s horn or flash its lights, or even disable its ignition and leave a driver stranded.

They like to say, ‘Oh, it’s Iran.’ Iran should be so lucky.

Iran’s got bigger problems than worrying about Minnesota.”No word on whether he believes the other six states have hacked themselves as well.

OpenAI was running security tests on two of its models: GPT-5.6 Sol and an unreleased model that is almost certainly GPT-6.

Modern AI models exhibit genie behavior: They can do what you ask in ways that you don’t expect or want.

There’s nothing magic about OpenAI’s frontier models; lots of models could have done the same thing.

Even if the U.S. frontier AI companies had some technical advantage, it’s now only a few months’ worth.

Even worse, U.S. companies limit access to their most sophisticated models, fearing being banned by the government if they do not do so.

On the IPI benchmark, Opus 5 improved over Opus 4.8, reducing the probability of an attacker succeeding within 15 attempts from 5.5% to 2.0%, and from 0.5% to 0.2% on 1 attempt.

It also improved on Sonnet 5 (5.9% at k=15) and Mythos 5 (2.6%), making it the most robust model evaluated.

The most robust non-Claude model was Muse Spark at 16.5% within 15 attempts—more than eight times Opus 5’s rate.

The other GPT 5.6 variants are less robust, at 30.4% (Terra) and 43.9% (Luna).

A single attempt against GPT 5.6 Sol succeeded 3.1% of the time, higher than the 2.0% an attacker achieved against Opus 5 after fifteen attempts.

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.

AD FRAUDBitsight found the H96 devices were either relaying residential proxy traffic or participating in ad fraud, but never both at the same time.

When the TV is off, it switches back to waiting for ad fraud jobs.

In addition to enlisting the user’s TV box in ad fraud networks, these off-brand streaming devices almost universally come with residential proxy software pre-installed.

In January, the proxy tracking service Synthient documented how multiple botnets had rapidly enslaved millions of TV boxes using a complex interplay of security vulnerabilities in …

The home appliance giant LG Electronics USA said this week it plans to suspend any apps built for its smart TVs that turn one’s television into an always-on residential proxy node.

On July 2, we featured research by the security firm Spur that examined the prevalence of residential proxy software development kits (SDKs) in smart TV apps.

“A residential proxy network is not an intended use for LG smart TVs, and LG Electronics is working with developers to remove the residential proxy option from their apps on the webOS platform,” Taylor said.

In the case of LG and Samsung smart TVs, Spur found residential proxy SDKs bundled with everything from simple games like Pac-Man to screensavers and f…

Microsoft attributed the burgeoning patch counts to vulnerability discoveries aided by artificial intelligence.

Microsoft also addressed three zero-day flaws that are already being exploited in the wild.

As AI advances the state of vulnerability discovery and remediation, it is also making it easier for attackers to quickly devise working exploits for known software flaws.

Backing up your Windows system and/or data is always a good idea before applying operating system updates.

It’s not uncommon for security patches to introduce system stability issues, and those chances probably increase quite a bit with the gigantic patch count released today.

Experts say the gaps identified in the agency’s initial response provide important lessons that all security teams should absorb.

CISA also admitted it can do better when it comes to responding to security incident notifications from external parties.

The website claims IRIS C2 is in the business of acquiring “zero-day exploits, individual primitives, partial chains, and full capabilities across all major platforms.

When approached with questions about IRIS C2, Burkman referred further inquiries to his longtime associate, 28-year-old Jacob Wohl.

Benjamin Brundage is founder of the proxy tracking service Synthient, one of the companies that published evidence last month linking the Popa botnet to NetNut and Alarum Technologies.

Brundage said the domain seizures appear to have disrupted both the Popa botnet and the NetNut proxy network that rides on top of it.

“Google has high confidence that many popular residential proxy brands are in fact whitelabeling the NetNut botnet,” the GTIG report concludes.

What we have observed is that when faced with the degradation of their own botnet, proxy operators begin buying capacity from their competitors, effectively becoming a reseller.

The duo were key members of a prolific cybercrime group known as Scattered Spider, and their guilty pleas came on the first day of what was expected to be a six-week trial.

In April 2026, 24-year-old British national and Scattered Spider member Tyler “Tylerb” Buchanan pleaded guilty to wire fraud conspiracy and aggravated identity theft for participating in the group’s SMS phishing spree in the summer of 2022.

The government said Buchanan, Jubair and others used the credentials harvested in that phishing campaign to steal at least $8 million in cryptocurrency from victims throughout the United States.

This week, researchers from multiple security firms concluded that the Popa botnet is linked to NetNut, a “residential proxy” provider operated by the publicly-traded Israeli firm Alarum Technologies Ltd [NASDAQ: ALAR].

Qurium said that immediately after that disruption, several dozen new domains were registered to serve as controllers for the Popa botnet, but that one of those control domains was not new: ninjatech[.]io.

This post examines clues pointing to a real life identity for the administrator of The Gentlemen ransomware group.

Experts at the security firm Check Point Software have been closely covering exploits of The Gentlemen, a so-called “ransomware-as-a-service” (RaaS) offering that pays affiliates handsomely to help spread the group’s malware.

According to Check Point, the group targets Internet-facing devices (VPNs, firewalls) as their entry point, and once inside moves quickly to encrypt entire networks within hours.

Check Point says the administrator and primary operator of the ransomware group uses the nickname Zeta88 on the Russian-language cybercrime forums, and that this individual was pr…

Microsoft today released software updates to plug nearly 200 security holes across its Windows operating systems and supported software, a record number of fixes for the company’s monthly Patch Tuesday cycle.

“Some surveys put AI usage among security professionals generally at 90%, so it’s unsurprising that this volume of patches may be the norm,” Narang said.

Microsoft received heavily blowback on social media last month after it said in a blog post that it was considering taking legal action against the security researcher.

While 200 vulnerabilities may be a record for Patch Tuesday, the actual number of security flaws Microsoft addressed this month is far higher, said Rapid7’s Adam Barne…

On May 31, word began to spread on several Telegram instant message channels that Meta’s AI bot would happily add an email address to an existing account as part of the bot’s standard password reset flow.

Meta has not responded to requests for comment on the video’s claims, but the company reportedly did acknowledge the dormant Instagram account for the Obama White House was briefly compromised.

Meta’s solution was to deploy a conversational AI layer to handle common recovery workflows: relinking a lost email address, triggering a password reset, verifying account ownership.

Just like human customer support employees can be social engineered into providing unauthorized access to someone’s a…

But as KrebsOnSecurity observed in September 2025, those sanctions failed to target Stark’s remaining connection to the Internet — an Internet service provider based in the Netherlands called MIRhosting.

MIRhosting is operated by Andrey Nesterenko, a 39-year-old Russian native who runs the business out of the Netherlands.

And as our September 2025 report showed, WorkTitans was controlled by Nesterenko and a 57-year-old from Amsterdam named Youssef Zinad.

On top of that, WorkTitans was getting connectivity to the larger Internet solely through MIRhosting, where Zinad had worked previously.

“The transition to the.hosting was not intended to evade sanctions,” Nesterenko wrote.

The inquiry comes as CISA is still struggling to contain the breach and invalidate the leaked credentials.

Experts who reviewed the exposed secrets said the commit logs for the code repository showed the CISA contractor disabled GitHub’s built-in protection against publishing sensitive credentials in public repos.

CISA acknowledged the leak but has not responded to questions about the duration of the data exposure.

TruffleHog does this by monitoring a live feed that GitHub publishes which includes a record of all commits and changes to public code repositories.

In practical terms, it is likely that cybercrime groups or foreign adversaries also noticed the publication of these CISA secrets, …

According to a report in the Financial Times, Apple has found itself facing a massive influx of submissions from amateur bug hunters who have used AI to generate plausible-sounding but completely hallucinated bug reports.

Unlike traditional spam, AI-generated bug reports include code which may be syntactically correct, references to genuine API calls, and plausible-sounding technical explanations of what is occurring.

But the hallucinated bug report may only have taken a few seconds for an amateur to generate and submit.

Previously, without the assistance of AI, Bynario had filed only 13 bug reports across 2025 and early 2026.

Apple is not the only company trying to deal with a deluge of au…

How a fake police officer nearly stole Graham's cryptocurrency with Graham Cluley and special guest Danny Palmer.

I said, without being big-headed, it is possible he knows me, but I don't know him.

I don't think my hotels tend to ask me to install something on my computer when I get there.

We had internet, but it was really, really restricted.

And it's really, really good.

As Coinbase's security team explains, the letters urge recipients to scan a QR code and enrol in a "Digital Asset Compliance Portal" before time runs out.

Bear in mind that the criminals could easily vary these details from letter to letter.

The scam site then asks victims to estimate how much value they have in their cryptocurrency wallets, with ranges up to "$100,000+".

Perhaps a reason why a scam like this can work is that the IRS has been tightening cryptocurrency holders' requirement to report details of their digital assets on their tax returns.

As a result, written communications between the IRS and holders of cryptocurrency have become more frequent.

According to the newly-published study, phishing and social engineering are becoming more expensive to recover from, trickier to detect, and increasingly augmented by artificial intelligence. Read more in my article on the Fortra blog.

For years, North Korea's state-trained hackers have been one of the world's most prolific robbers of banks - stealing huge sums of money from foreign financial instituions, draining cryptocurrency exchanges of billions, and funnelling the proceeds into the country's weapons programme.

But now, in a remarkable twist, some of the same elite hackers appear to have decided to rob their own government instead.

The ringleaders of the group are said to be discharged veterans from a cyber operations unit under North Korea's Reconnaissance and Intelligence General Bureau.

In short, the hackers are accused of building a mini version of the same kind of money-laundering infrastructure North Korea depl…

Smashing Security, Episode 478: This Job Interview Could Destroy Your Company, with Graham Cluley and special guest Paul Ducklin.

And all the time you're going through this process, bad news, they really were recording video of you.

Obviously, you can understand that CAR want to know, does your car actually have one of these in all likelihood?

And give it to them and then they tell you whether they think you're at risk.

I don't know.

The AI models involved were OpenAI's GPT-5.6 Sol and a more capable, as-yet-unreleased model.

The intention of OpenAI's researchers was to get a clear picture of what the AI models were capable of achieving if not constrained.

American AI safety guardrails forced a US company to turn to a Chinese AI model for help.

Hugging Face's CEO Clément Delangue is quoted in OpenAI's blog post, calling on the AI industry to work more collaboratively.

It is clear that advanced AI models are remarkably capable of discovering and exploiting ways to attack real-world systems.

How 14 orders of Chicken McNuggets helped nail a suspected Russian hacker with Graham Cluley and special guest James Ball.

I had a vindaloo, Graham Cluley, and I don't think it ever touched capsicum.

Yeah, I think you're right.

If you use Suno music, people say, you know, you're killing music.

I don't know much about Shai Hulud.

Ukraine's computer emergency response team, CERT-UA, has warned that Russian hackers are using fake CAPTCHA checks to trick people into compromising their own PCs.

The Kremlin-backed Sandworm hacking group is reportedly leveraging fake CAPTCHA checks on compromised websites that persuade users to execute a PowerShell command on their computers - tricking them into running malicious code.

The latest attacks begin when a user visits a compromised webpage, where they're greeted by a fake CAPTCHA claiming they need to complete an extra step to prove that they are human.

Instead, the fake CAPTCHA instructs the user to copy and paste a PowerShell command into their Windows computer.

They are a pr…

Someone gets hold of your locked Android phone and, despite not knowing your security PIN, they can send messages via SMS or WhatsApp pretending to come from you.

It is clear that Google has patched Gemini lock screen issues before, but security researchers keep finding new ways through.

The latest vulnerability is different from the previous similar Gemini-based Android lock screen bypass bugs that have been plaguing the operating system since September 2025.

To do that:Open the Gemini app, tap your profile picture, go to Settings, and select "Gemini on lock screen."

Every new capability Gemini is given at the lock screen is also a new potential attack surface.

The Anubis ransomware-as-a-service (RaaS) operation has hit some healthcare organisations hard - but they are not the only ones at risk. Read more in my article on the Fortra blog.

When a company falls victim to a ransomware attack, it is not uncommon for it to turn to experts for help.

Specialist ransomware negotiation firms handle communications with criminal gangs on a victim's behalf.

41-year-old Martino worked as a ransomware negotiator for DigitalMint, an incident response company based in Chicago.

The ransomware victim, a hospitality company, ultimately paid out nearly US $16.5 million.

The company has since changed the way its negotiators communicate with ransomware gangs, and is working with the Department of Homeland Security to establish a registry for the currently highly-unregulated world of ransomware negotiation.

Have you received an email from a recruiter at Adobe, Netflix, or OpenAI offering you an exciting new marketing role?

Security experts have uncovered a phishing campaign which impersonates over 30 well-known brands in fake job interviews designed to steal Google account passwords.

When victims click on "Continue with Google," a pop-up appears that looks like a legitimate Google authentication dialog.

In the past the FBI has warned the public about scammers using fake job ads to steal money and personal information from applicants.

Earlier this year, Hot for Security published a guide explaining how many fake recruiter scams work, and how to avoid them.

AI Is Changing the Traffic ModelMuch of the enterprise AI conversation centers on models, GPUs, data platforms, and agents.

Time-sensitive performance: Voice AI, edge AI, and physical AI move latency into live operations.

SD-WAN can help maintain operations by prioritizing critical traffic, steering it across the best available path, and applying consistent policy across locations.

Why AI Traffic is an SD-WAN ProblemSD-WAN sits at the point where application intent meets real network conditions.

Their recommendations for securing the AI era rely heavily on establishing strict asset inventory and preventing lateral movement—which are, at their core, fundamental Zero Trust principles.

The Three Core Principles of Zero Trust for AIFounded in three core principles, a robust Zero Trust architecture requires us to execute the following phases comprehensively.

Achieving the Architectural VisionThe above may all sound like pipedream, as most organisations struggle with Zero Trust programs and undelivered microsegmentation projects.

Ultimately AI driven platform approach is what makes Zero Trust achievable for the frontier AI era.

This is exactly why achieving a Zero Trust Architecture for …

This provides an opportunity for defenders: if we assume our controls will fail at some point, we can build a much more resilient architecture.

When you assume the current layer will eventually be bypassed, you start designing the next layer proactively instead of reactively.

Defenders need to advance their controls by mapping them to the adversaries’ capabilities then assume that control will fail.

Map your controls to the attack chain.

Call to Action:If you haven’t watched the full video yet, go check it out: Assuming Failure Provides Better Defensive Outcomes (bonus elements around SOC of the Future and business context).

Consequently, the approach shifts toward a logically air-gapped architecture based on a full-stack governance model, which replaces physical barriers with a robust, software-defined cryptographic perimeter.

This “Logically Air-Gapped” governance model reaches its full operational potential through the implementation of “Live Protect.” As a runtime security module, Live Protect elevates protection from the configuration plane to that of dynamic execution.

Reference ArchitectureDigital autonomy is thus exercised by shifting network and security control into the operating system kernel.

That is why we are introducing Firewall Migration Manager by Cisco, an enterprise-ready product built for that reality.

What Is Firewall Migration Manager?

Firewall Migration Manager is a dedicated migration application that you run in your own environment.

How Firewall Migration Manager WorksThe migration process follows a clear, guided workflow.

Intelligent, integrated migration: Firewall Migration Manager will also come to Cisco Cloud Control, and AI will play an increasing role in guiding teams before and during migration.

In independent testing with NetSecOPEN, the Cisco Secure Firewall 6160 delivered AI-scale inspected throughput beyond what the tools built to measure it could register, all while blocking 100% of tested threats.

These results are specific to Cisco Secure Firewall 6160, but the software capabilities behind Cisco Firewall, including advanced threat protection and high-performance inspection, extend across Cisco Firewall form factors in the cloud, virtually, and on-premises, from campus to data center.

Performance passed the previous benchmark by 5XInspection was turned on, and the test tools built to measure throughput hit their limit before the 6160 firewall did.

Having spent time in the Cisco Live Americas 2026 SOC, one thing became abundantly clear:The way SOCs operate today is fundamentally different from even a few years ago.

Instead of spending time gathering information, analysts could spend more time understanding what the information actually meant.

Just as spreadsheets empowered business users decades ago, AI-assisted coding is beginning to empower security analysts today.

At Cisco Live, AI was already present throughout the workflow:Incident summaries generated automatically within XDR.

And based on what I saw at Cisco Live 2026, that future has already arrived.

The new SOC analysts were great at finding evidence, helped with triage and correlation by the AI agents in the SOC architecture.

With the advancements in Cloud Control, our new SOC Analysts can validate their hypothesis.

They had the ability to investigate the incident and find the root cause found in Splunk Security and Endace.

Instant Attack VerificationIn each Incident, the SOC Analysts is given an AI generated Summary stitching all the relevant logs from all the sources that are related to the objects in question.

Check out the blogs by the engineers who worked inside the SOC at Las Vegas:

At Cisco Live AMER 2026 in Las Vegas, my work with the Cisco Event SOC centered on one outcome that makes these deployments valuable beyond the event itself: Education.

The SOC protects the conference, but it also turns live operations into a learning environment through SOC tours, Cisco Live sessions, training inside the SOC, and conversations in the World of Solutions.

Bringing live SOC lessons into the classroomEducation also happened in the sessions I delivered at Cisco Live.

Cisco Live AMER 2026 reinforced that the SOC is one of the best classrooms we have because it teaches through real operations.

Inside the Cisco Live SOCAt Cisco Live AMER, the Security Operations Center (SOC) is more than a demo environment.

For a broader look at how the Cisco Live SOC operates, read this overview.

Another part was spent in the SOC, working real investigations with XDR, Splunk Enterprise Security, firewall events, DNS telemetry, packet data, and AI assistance.

AI can help a product manager become useful faster in a live SOC.

That is the bar I want us to continue building toward as we build Cisco XDR and Splunk Security.

As part of the Cisco XDR (Extended Detection and Response) product engineering group, a few of us got exactly that chance.

Every product had a part to play for a network as traffic-heavy as Cisco Live.

(PS : Flaunting the SOC T-shirts was fun)AcknowledgementsA heartfelt thank you to Cisco and the entire SOC team — you are all amazing.

That starts with asking better questions—the kind that help organizations turn intelligence into action and trust into a foundation for progress.

But better security does not start with more information.

Understanding those connections is what allows security teams to use platforms, AI, and automation to make better decisions under real-world conditions.

Better analysis can surface more insights, but better decisions still depend on understanding what matters most and applying the right context.

Better security starts with better questions, and with the clarity to act on them.

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.

Malicious: ExfiltrationWe were able to observe a small number of prompt injections that aim at theft of data.

Following our previous discussion on "Deploying Rust in Existing Firmware Codebases", this post shares a concrete application: integrating a memory-safe Rust DNS(Domain Name System) parser into the modem firmware.

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…

For Majik, Scam Detection was the intervention he needed: “The warning is what made me pause and avoid a bad situation”.

Powered by Gemini’s on-device model, Scam Detection provides intelligent protection against scam calls while ensuring that…

Upgrading Google Play’s AI-powered, multi-layered user protectionsWe’ve seen a clear impact from these safety efforts on Google Play.

As Android’s built-in defense against malware and unwanted software, Google Play Protect now scans over 350 billion Android apps daily.

This proactive protection constantly checks both Play apps and those from other sources to ensure they are not potentially harmful.

Looking aheadOur top priority remains making Google Play and Android the most trusted app ecosystems for everyone.

Thank you for being part of the Google Play and Android community as we work together to build a safer app ecosystem.

That’s why we're committed to providing multi-layered defenses that help protect you before, during, and after a theft attempt.

Today, we're announcing a powerful set of theft protection feature updates that build on our existing protections, designed to give you greater peace of mind by making your device a much harder target for criminals.

These updates are now available for Android devices running Android 16+.

More User Control for Failed Authentications: In Android 15, we launched Failed Authentication Lock, a feature that automatically locks the device's screen after excessive failed authentication attempts.

This feature is now getting a new dedicated enable/disable toggle in settings,…

These initiatives, driven by Ballots SC-080, SC-090, and SC-091, will sunset 11 legacy methods for Domain Control Validation.

What’s Domain Control Validation?

Domain Control Validation is a security-critical process designed to ensure certificates are only issued to the legitimate domain operator.

Sunsetted methods relying on email:Sunsetted methods relying on phone:Sunsetted method relying on a reverse lookup:For everyday users, these changes are invisible - and that’s the point.

These changes push the ecosystem toward standardized (e.g., ACME), modern, and auditable Domain Control Validation methods.

Partnership with ArmOur goal is to raise the bar on GPU security, ensuring the Mali GPU driver and firmware remain highly resilient against potential threats.

We partnered with Arm to conduct an analysis of the Mali driver, used on approximately 45% of Android devices.

This approach allowed us to roll out the new security policy broadly while minimizing the impact on developers.

This effort spans across Android and Android OEMs, and required close collaboration with Arm.

The Android security team is committed to collaborating with ecosystem partners to drive broader adoption of this approach to help harden the GPU.

We built on Gemini's existing protections and agent security principles and have implemented several new layers for Chrome.

To further bolster model alignment beyond spotlighting, we’re introducing the User Alignment Critic — a separate model built with Gemini that acts as a high-trust system component.

A flow chart that depicts the User Alignment Critic: a trusted component that vets each action before it reaches the browser.

The User Alignment Critic runs after the planning is complete to double-check each proposed action.

Looking forwardThe upcoming introduction of agentic capabilities in Chrome brings new demands for browser security, and we've approached this challenge with the same ri…

Android uses the best of Google AI and our advanced security expertise to tackle mobile scams from every angle.

Over the last few years, we’ve launched industry-leading features to detect scams and protect users across phone calls, text messages and messaging app chat notifications.

To help combat these types of financial scams, we launched a pilot earlier this year in the UK focused on in-call protections for financial apps.

The UK pilot of Android’s in-call scam protections has already helped thousands of users end calls that could have cost them a significant amount of money.

We’ve also started to pilot this protection with more app types, including peer-to-peer (P2P) payment apps.

Secure by DesignWe built Quick Share’s interoperability support for AirDrop with the same rigorous security standards that we apply to all Google products.
