    Lucid Dreams I: Lucid’s First Time Fuzzing
    Background We’ve spent a lot of time so far on this blog documenting the development process of Lucid, our full-system snapshot fuzzer, and I really wanted to start using it to do some real fuzzing. So the focus of this blog post will be documenting the process I had to take to get Lucid up and fuzzing on a real target. So far, Lucid has only worked on a toy harness/example, and so we need to see what kind of things need tweaking when a real target comes into play.  ( 26 min )

The encryption occurs in the browser before data reaches Google's servers, allowing organizations to maintain control over their encryption keys while external recipients access encrypted messages through guest accounts without requiring S/MIME certificate exchanges.

    [ru] Kernel-hack-drill и новый эксплойт для CVE-2024-50264 в ядре Linux
    Некоторые уязвимости, связанные с повреждением памяти, невероятно сложны для эксплуатации. Они могут вызывать состояния гонки, приводить к сбоям системы и накладывать разные ограничения, которые усложняют жизнь исследователя. Работа с такими «хрупкими» багами требует значительно больше времени и усилий. CVE-2024-50264 в ядре Linux — как раз одна из таких сложных уязвимостей, которая получила премию Pwnie Award 2025 в категории «Лучшее повышение привилегий» (Best Privilege Escalation). В этой статье я представлю свой проект kernel-hack-drill и покажу, как он помог мне разработать прототип эксплойта для уязвимости CVE-2024-50264.  ( 23 min )

    Windows 10 end of support: Extended Security Updates (ESU), Windows 11 hardware requirements, upgrade options
    With Windows 10's end of support approaching on October 14, 2025, many organizations and users face critical decisions about their computers' future security and functionality. Microsoft will cease providing essential security updates and technical support for Windows 10, leaving devices vulnerable to emerging cyber threats and compatibility issues. While some users can upgrade to Windows 11, strict hardware requirements, including TPM 2.0 and newer processors, mean many functional computers won't qualify for the transition. Organizations and consumers must now evaluate their options, from purchasing Extended Security Updates (ESU) to exploring alternative operating systems or investing in new hardware. User communities are expressing growing frustration with Microsoft's hardware requirements, viewing them as forced obsolescence that creates unnecessary electronic waste and unfair costs for owners of perfectly functional devices.

    Pointer leaks through pointer-keyed data structures
    Posted by Jann Horn, Google Project Zero Introduction Some time in 2024, during a Project Zero team discussion, we were talking about how remote ASLR leaks would be helpful or necessary for exploiting some types of memory corruption bugs, specifically in the context of Apple devices. Coming from the angle of "where would be a good first place to look for a remote ASLR leak", this led to the discovery of a trick that could potentially be used to leak a pointer remotely, without any memory safety violations or timing attacks, in scenarios where an attack surface can be reached that deserializes attacker-provided data, re-serializes the resulting objects, and sends the re-serialized data back to the attacker. The team brainstormed, and we couldn't immediately come up with any specific atta…  ( 21 min )

    Upgrade from Office 2016, 2019 – Office 2024 vs Microsoft 365 Apps
    The end of support for Office 2016 and Office 2019 on October 14, 2025, forces organizations to choose between upgrading to Office 2024 or adopting Microsoft 365 Apps. Both solutions offer Office applications like Word, Excel, and PowerPoint, but differ significantly in pricing models, AI capabilities, cloud integration, and update cycles. While Office 2024 delivers a one-time purchase with long-term stability and offline functionality, Microsoft 365 Apps provides continuous feature updates, AI-powered Copilot integration, and collaborative cloud tools through a subscription model. This guide compares Office 2024 vs. Microsoft 365 Apps to help you make the right upgrade decision before support ends. Source

    Yet Another Random Story: VBScript's Randomize Internals

    One Token to rule them all - obtaining Global Admin in every Entra ID tenant via Actor tokens
    While preparing for my Black Hat and DEF CON talks in July of this year, I found the most impactful Entra ID vulnerability that I will probably ever find. One that could have allowed me to compromise every Entra ID tenant in the world (except probably those in national cloud deployments). If you are an Entra ID admin reading this, yes that means complete access to your tenant. The vulnerability consisted of two components: undocumented impersonation tokens that Microsoft uses in their backend for service-to-service (S2S) communication, called "Actor tokens", and a critical vulnerability in the (legacy) Azure AD Graph API that did not properly validate the originating tenant, allowing these tokens to be used for cross-tenant access.  ( 13 min )
