The AI-agent ecosystem experienced its largest supply-chain compromise to date when ClawHavoc detonated across ClawHub, the official skill marketplace for OpenClaw. Our full AIG-powered scan of nearly 50,000 ClawHub Skills found 1,184 clearly malicious packages tied to 12 compromised publisher accounts and confirmed 247,693 installations. The campaign combined typosquatting, ranking manipulation, and multi-stage payload delivery […]

Threat actors are actively exploiting CVE-2026-33017, a critical unauthenticated remote code execution (RCE) vulnerability in Langflow, to compromise internet-exposed AI application servers and silently deploy a customized Monero (XMR) cryptominer. Tracked and documented by Trend Micro researchers Simon Dulude and John Zhang, the campaign marks a significant pivot in commodity cryptominer delivery tactics, from traditional […]

A newly documented injection technique abuses the kernel-to-user callback dispatch path used by the Windows graphical subsystem (win32k.sys) to achieve remote code execution while leaving the KernelCallbackTable structurally intact. Rather than replacing a KernelCallbackTable entry with a shellcode pointer, the operator resolves a legitimate callback target from the table and installs an inline detour inside […]

The emergence of LLM-driven “disposable tooling” is reshaping offensive tradecraft and forcing defenders to rethink detection models that rely on static signatures and known implant behaviors. Recent experiments demonstrating the automated generation of Mythic agents from prompt to deployment reveal a new threat class: ephemeral, single-use implants tailor-made by large language models and orchestration harnesses. […]

Microsoft has shut down a long-running malicious extension operation on the Edge Add-ons store that hid its payloads inside ordinary image and font files, then woke up days after install to steal credentials and run ad fraud. The company calls it StegoAd, a mash-up of steganography and adware, and ties 119 extensions to a single threat actor it says has been active since at least 2021.
