    Linux kernel security list is drowning in duplicate AI-flagged bugs; same issues, with same tools, but different names of human submitters. Maintainers have now formalized the obvious - AI-found bugs are public by definition. New docs define 5 failure modes for AI-assisted reports: too long, Markdown-heavy, threat model-ignorant, reproducer-free, patch-free. Non-compliant reports risk being ignored. Most AI-flagged issues aren’t even real vulnerabilities anyway. 500 submitters, 1 CVE, 0 patches?

    My comment for WSJ. Trolling is now a standard tool of statecraft. Lego, Call of Duty, Grand Theft Auto or Nintendo work well as propaganda because they are universally recognised cultural cues with preloaded emotional associations. They are also perfect for fast-paced communication styles. Expect this new approach to diplomacy, signaling, international relations, and information operations to be used more frequently. https://www.wsj.com/world/lego-ai-propaganda-wars-iran-ab29cc6c

    Cyberattack on Jaguar Land Rover results in a prolonged production shutdown. 25% of suppliers have already taken steps to pause production and temporarily lay off workers. The attack has now forced a complete halt until October 1st, costing the company over $1.36 billion in lost revenue and affecting 200,000+ jobs across the supply chain. This is one of the most devastating cybersecurity incidents in automotive history.

    AI vulnerability/bug founds and reports is a huge problem. Curl has banned the use of AI-generated submissions via HackerOne because none of it made any sense, and is a waste of resources and time. "We are effectively being DDoSed.

    No cyber threat actor has been found to use any public AI/LLM for serious cyberattack/cyberoperation goals. Unless they're trolling, because it is already possible to such tools in completely undetectable ways. Cybersecurity and LLM providers have no visibility here.

    Beware of narrative stretches used for PR purposes. Even a single packet sent from a Ukrainian IP in a DDoS attack on X platform doesn’t imply 'Ukraine behind it'. This is an oversimplification, perhaps to to divert attention. Attribution doesn’t work that way—an IP is inconclusive. And much of Ukraine is occupied, with traffic operated by Russian ISPs.

    Malicious open source models are being uploaded to popular repository hugging face. This will be a completely new cybersecurity risk. Now it's merely code execution. But expect tainted/poisoned weights impacting outputs. Python reverse shell script enables remote command execution.

      GAZEploit: Remote Keystroke Inference Attack by Gaze Estimation from Avatar Views in VR/MR Devices
      The advent and growing popularity of Virtual Reality (VR) and Mixed Reality (MR) solutions have revolutionized the way we interact with digital platforms. The cutting-edge gaze-controlled typing methods, now prevalent in high-end models of these devices, e.g., Apple Vision Pro, have not only improved user experience but also mitigated traditional keystroke inference attacks that relied on hand gestures, head movements and acoustic side-channels. However, this advancement has paradoxically given birth to a new, potentially more insidious cyber threat, GAZEploit. In this paper, we unveil GAZEploit, a novel eye-tracking based attack specifically designed to exploit these eye-tracking information by leveraging the common use of virtual appearances in VR applications. This widespread usage significantly enhances the practicality and feasibility of our attack compared to existing methods. GAZEploit takes advantage of this vulnerability to remotely extract gaze estimations and steal sensitive keystroke information across various typing scenarios-including messages, passwords, URLs, emails, and passcodes. Our research, involving 30 participants, achieved over 80% accuracy in keystroke inference. Alarmingly, our study also identified over 15 top-rated apps in the Apple Store as vulnerable to the GAZEploit attack, emphasizing the urgent need for bolstered security measures for this state-of-the-art VR/MR text entry method.
