Trail of Bits crafted four malicious agent skills that bypass Cisco, Vercel, and ClawHub scanners by padding code or embedding payloads in docx and bytecode. The article shows how Siri-AI’s integration with private cloud compute and search can expose messages, emails, and calendars through prompt injection. It also covers a PyPI worm that auto-executes a hades-setup.pth hook to steal cloud and GitHub tokens, urging audits and immediate token rotation.

• Trail of Bits bypassed Cisco, Vercel, and ClawHub agent-skill scanners using tricks like 10,000 newlines of padding, or hiding payloads in .docx files and compiled Python bytecode—none of the scanners caught the buried triggers.
• Siri-AI's use of Gemini via Apple Private Cloud Compute pulls in messages, email, notes, and calendars, making it vulnerable to prompt injection that can leak private data or trigger unwanted actions like forwarding sensitive material.
• Socket found a PyPI supply-chain attack hijacking 19 packages (37 malicious wheels) that drop a hades-setup.pth hook to run an embedded Bun runtime, stealing AWS/GCP/Azure, GitHub, npm, and SSH credentials and exfiltrating them to GitHub repos while disguising traffic as Anthropic API calls.
• Affected package names include bramin, executor-engine, executor-http, funcdesc, coolbox, dynamo-release, and magique—any match warrants full credential rotation and a CI/CD log audit.
