    Scary Agent Skills: Hidden Unicode Instructions in Skills ...And How To Catch Them
    There is a lot of talk about Skills recently, both in terms of capabilities and security concerns. However, so far I haven’t seen anyone bring up hidden prompt injection. So, I figured to demo a Skills supply chain backdoor that survives human review. Additionally, I also built a basic scanner, and had my agent propose updates to OpenClaw to catch such attacks. Attack Surface Skills introduce common threats, like prompt injection, supply chain attacks, RCE, data exfiltration,… This post discusses some basics, highlights the most simple prompt injection avenue, and shows how one can backdoor a real Skill from OpenAI with invisible Unicode Tag codepoints that certain models, like Gemini, Claude, Grok are known to interpret as instructions.  ( 6 min )

    Update expiring Windows Secure Boot certificates now
    Microsoft's original Secure Boot certificates, issued in 2011, begin expiring in late June 2026, potentially affecting millions of Windows devices worldwide. While your device will continue to boot normally after expiration, it will enter a degraded security state where new boot-level protections cannot be applied. To maintain full protection against emerging threats, ensure your system receives the latest 2023 certificates before the deadline. Source
    Windows 11 KB5074110 and KB5074111 updates enhance setup and recovery
    Microsoft released two dynamic updates for Windows 11 on January 29, 2026, targeting the setup and recovery infrastructure. KB5074110 is particularly important because older Secure Boot certificates will begin expiring in June 2026. KB5074110 and KB5074111 also bring improvements to feature update installations and recovery tools for Windows 11 versions 24H2 and 25H2. These updates ensure smoother upgrades and more reliable system recovery without introducing new user-facing features. Source

    Scan OpenClaw agent skills for security vulnerabilities with the Cisco AI Skill Scanner
    OpenClaw, previously known as Clawdbot and briefly as Moltbot, is a free, open‑source personal AI agent that runs locally on your computer, enabling you to automate any task a human can perform on a computer. It gained rapid popularity, accumulating 100,000 GitHub stars in record time, along with tens of thousands of forks as it went viral. OpenClaw skills pose severe security risks because they are unvetted modules that may contain hidden, malicious instructions for the agent's model. These harmful instructions could result in API key leaks, data theft, credential compromise, and system breaches due to malicious code execution. This guide covers OpenClaw skill structure, known security incidents, and step-by-step instructions for scanning agent skills with the Cisco AI Skill Scanner. The Cisco AI Skill Scanner provides comprehensive security analysis of OpenClaw agent skills before installation, detecting malware, data exfiltration, and prompt-injection vulnerabilities. Source

    Deterministic AI Orchestration: A Platform Architecture for Autonomous Development
    Executive Summary The primary bottleneck in autonomous software development is not model intelligence, but context management and architectural determinism. Current “Agentic” approaches fail at scale because they rely on probabilistic guidance (prompts) for deterministic engineering tasks (builds, security, state management). Furthermore, the linear cost of token consumption versus the non-linear degradation of model attention creates a “Context Trap” […] The post Deterministic AI Orchestration: A Platform Architecture for Autonomous Development appeared first on Praetorian.  ( 27 min )

    OpenAI Explains URL-Based Data Exfiltration Mitigations in New Paper
    Last week I saw this paper from OpenAI called “Preventing URL-Based Data Exfiltration in Language-Model Agents”, which goes into detail on new mitigations they’ve added. This is a great read. I like this transparency. Initial Disclosure in 2023 Nearly three years ago I reported the zero-click data exfiltration exploit to OpenAI. Back in early 2023 OpenAI did not have a bug bounty program, so communication was via email, and unfortunately there was little traction or appetite to fix the problem in ChatGPT. I also reported the same issue to Microsoft as Bing Chat was impacted, and Microsoft applied a fix (via a Content-Security-Policy header) in May 2023 to generally prevent loading of images.  ( 4 min )

    In July 2025, we performed a brief audit of Outline - an OSS wiki similar in many ways to Notion.

    Microsoft Entra ID fixes Conditional Access policy bypass, will enforce MFA sign-in for OIDC-only requests
    Microsoft will improve how Conditional Access policies are enforced in Microsoft Entra ID starting March 27, 2026. This change addresses a security loophole in which policies targeting all resources with specific exclusions could be bypassed in certain authentication scenarios. The rollout continues through June 2026 and forms part of Microsoft's Secure Future Initiative. Because these sign-ins will no longer bypass Conditional Access, users may now be required to complete MFA, meet device compliance requirements, or satisfy other configured Conditional Access controls, such as approved apps, app protection policies, or authentication strength, before accessing the resource.

    Celebrating our 2025 open-source contributions
    Last year, our engineers submitted over 375 pull requests that were merged into non–Trail of Bits repositories, touching more than 90 projects from cryptography libraries to the Rust compiler. This work reflects one of our driving values: “share what others can use.” The measure isn’t whether you share something, but whether it’s actually useful to someone else. This principle is why we publish handbooks, write blog posts, and release tools like Claude skills, Slither, Buttercup, and Anamorpher. But this value isn’t limited to our own projects; we also share our efforts with the wider open-source community. When we hit limitations in tools we depend on, we fix them upstream. When we find ways to make the software ecosystem more secure, we contribute those improvements. Most of these contri…  ( 11 min )

    Breaking the Sound Barrier, Part II: Exploiting CVE-2024-54529
    In the first part of this series, I detailed my journey into macOS security research, which led to the discovery of a type confusion vulnerability (CVE-2024-54529) and a double-free vulnerability (CVE-2025-31235) in the coreaudiod system daemon through a process I call knowledge-driven fuzzing. While the first post focused on the process of finding the vulnerabilities, this post dives into the intricate process of exploiting the type confusion vulnerability. I’ll explain the technical details of turning a potentially exploitable crash into a working exploit: a journey filled with dead ends, creative problem solving, and ultimately, success. The Vulnerability: A Quick Recap If you haven’t already, I highly recommend reading my detailed writeup on this vulnerability before proceeding. As a refresher, CVE-2024-54529 is a type confusion vulnerability within the com.apple.audio.audiohald Mach service in the CoreAudio framework used by the coreaudiod process. Several Mach message handlers, such as _XIOContext_Fetch_Workgroup_Port, would fetch a HALS_Object from the Object Map based on an ID from the Mach message, and then perform operations on it, assuming it was of a specific type (ioct) without proper validation.  ( 10 min )

    Building cryptographic agility into Sigstore
    Software signatures carry an invisible expiration date. The container image or firmware you sign today might be deployed for 20 years, but the cryptographic signature protecting it may become untrustworthy within 10 years. SHA-1 certificates become worthless, weak RSA keys are banned, and quantum computers may crack today’s elliptic curve cryptography. The question isn’t whether our current signatures will fail, but whether we’re prepared for when they do. Sigstore, an open-source ecosystem for software signing, recognized this challenge early but initially chose security over flexibility by adopting new cryptographic algorithms as older ones became obsolete. By hard coding ECDSA with P-256 curves and SHA-256 throughout its infrastructure, Sigstore avoided the dangerous pitfalls that have …  ( 6 min )

    ConsentFix (a.k.a.AuthCodeFix) is the latest variant of the fix-type phishing attacks, initially identified by Push Security. In this technique, the adversary tricks the victim into generating an OAuth authorization code that is part of a localhost URL, by signing in to the Azure CLI instance (or other vulnerable applications). Then, the victim is instructed to copy that URL and paste it into a phishing website, essentially handing over the authorization code to the adversary, who is now able to exchange it for an access token. Using the access token, the adversary gets access to the victim's Microsoft account.  ( 19 min )

    Bypassing Windows Administrator Protection
    A headline feature introduced in the latest release of Windows 11, 25H2 is Administrator Protection. The goal of this feature is to replace User Account Control (UAC) with a more robust and importantly, securable system to allow a local user to access administrator privileges only when necessary. This blog post will give a brief overview of the new feature, how it works and how it’s different from UAC. I’ll then describe some of the security research I undertook while it was in the insider preview builds on Windows 11. Finally I’ll detail one of the nine separate vulnerabilities that I found to bypass the feature to silently gain full administrator privileges. All the issues that I reported to Microsoft have been fixed, either prior to the feature being officially released (in optional update KB5067036) or as subsequent security bulletins. Note: As of 1st December 2025 the Administrator Protection feature has been disabled by Microsoft while an application compatibility issue is dealt with. The issue is unlikely to be related to anything described in this blog post so the analysis doesn’t change.  ( 15 min )

    Intercepting OkHttp at Runtime With Frida - A Practical Guide
    Introduction OkHttp is the defacto standard HTTP client library for the Android ecosystem. It is therefore crucial for a security analyst to be able to dynamically eavesdrop the traffic generated by this library during testing. While it might seem easy, this task is far from trivial. Every request goes through a series of mutations between the initial request creation and the moment it is transmitted. Therefore, a single injection point might not be enough to get a full picture. One needs a different injection point to find out what is actually going through the wire, while another might be required to understand the initial payload being sent.

    A 0-click exploit chain for the Pixel 9 Part 3: Where do we go from here?
    While our previous two blog posts provided technical recommendations for increasing the effort required by attackers to develop 0-click exploit chains, our experience finding, reporting and exploiting these vulnerabilities highlighted some broader issues in the Android ecosystem. This post describes the problems we encountered and recommendations for improvement. Audio Attack Surface The Dolby UDC is part of the 0-click attack surface of most Android devices because of audio transcription in the Google Messages application. Incoming audio messages are transcribed before a user interacts with the message. On Pixel 9, a second process com.google.android.tts also decodes incoming audio. Its purpose is not completely clear, but it seems to be related to making incoming messages searchable.  ( 9 min )
    A 0-click exploit chain for the Pixel 9 Part 2: Cracking the Sandbox with a Big Wave
    With the advent of a potential Dolby Unified Decoder RCE exploit, it seemed prudent to see what kind of Linux kernel drivers might be accessible from the resulting userland context, the mediacodec context. As per the AOSP documentation, the mediacodec SELinux context is intended to be a constrained (a.k.a sandboxed) context where non-secure software decoders are utilized. Nevertheless, using my DriverCartographer tool, I discovered an interesting device driver, /dev/bigwave that was accessible from the mediacodec SELinux context. BigWave is hardware present on the Pixel SOC that accelerates AV1 decoding tasks, which explains why it is accessible from the mediacodec context. As previous research has copiously affirmed, Android drivers for hardware devices are prime places to find powerful local privilege escalation bugs. The BigWave driver was no exception - across a couple hours of auditing the code, I discovered three separate bugs, including one that was powerful enough to escape the mediacodec sandbox and get kernel arbitrary read/write on the Pixel 9.  ( 8 min )
    A 0-click exploit chain for the Pixel 9 Part 1: Decoding Dolby
    Over the past few years, several AI-powered features have been added to mobile phones that allow users to better search and understand their messages. One effect of this change is increased 0-click attack surface, as efficient analysis often requires message media to be decoded before the message is opened by the user. One such feature is audio transcription. Incoming SMS and RCS audio attachments received by Google Messages are now automatically decoded with no user interaction. As a result, audio decoders are now in the 0-click attack surface of most Android phones. I’ve spent a fair bit of time investigating these decoders, first reporting CVE-2025-49415 in the Monkey’s Audio codec on Samsung devices. Based on this research, the team reviewed the Dolby Unified Decoder, and Ivan Fratric and I reported CVE-2025-54957. This vulnerability is likely in the 0-click attack surface of most Android devices in use today. In parallel, Seth Jenkins investigated a driver accessible from the sandbox the decoder runs in on a Pixel 9, and reported CVE-2025-36934.  ( 36 min )
