Recent Developments

  • 2026-06-25: Published PoC “Clone This Repo and I Own Your Machine” — clean GitHub repo tricks claude Code into reverse shell via DNS TXT payload (2026-06-27-mozilla-0din-claude-code-github-malware, mozilla-0din-claude-code-github-malware)
  • Attack chain: Setup instructions → intentional init error → agent auto-runs fix → setup.sh fetches base64 payload from DNS TXT → bash execution
  • No malicious code in repository; payload swappable via DNS without repo changes
  • Distribution vectors: job postings, tutorials, DMs
  • Mitigation recommendation: Agents should disclose full execution chain including dynamically fetched content
