Each one is a little bundle of plain-English instructions, scripts, and files that a tool such as Claude Code or OpenAI Codex loads when it needs a new trick. One marketplace filled up with more than 40,000 listed skills within months of the format showing up in … More → The post Malicious AI agent skills can slip past the scanners built to stop them appeared first on Help Net Security.

Antivirus vendors and security startups keep shipping AI features that promise to read malware the way a seasoned analyst would. The results inside security teams tell a quieter story. A new paper argues that static analysis of software, the job of deciding whether a program is malicious by examining its contents on disk, remains one of the hardest places to make generative AI work. The scale of the problem explains much of the difficulty. Standard … More → The post A single malware file can outweigh an entire AI dataset appeared first on Help Net Security.
