Your AI and this story

  • GPT-6 Astra168 days after its cutoff
  • Claude Opus 5.5107 days after its cutoff
  • Gemini 4 Argon198 days after its cutoff
  • Grok 4.7137 days after its cutoff

None of these four assistants can know about it. The closest, Claude Opus 5.5, stops 107 days before it.

Key facts

  • New targets (Symantec): .claude.json, Claude desktop cookies, ChatGPT cookies, Codex config.toml and .env files; tokens for GitHub Copilot, Cursor, Google Gemini, JetBrains AI Assistant and Kiro; AWS credentials
  • Why it matters (Symantec): stolen API keys and OAuth/session tokens let attackers act under a developer’s identity and quota and can expose linked repositories, cloud services and CI/CD pipelines; it stole credential files, not source code, except Cursor’s local state database, which can cache chat context and code snippets
  • The malware has no backdoor command list; it sends whatever it collects to a C&C ‘/gate’ endpoint. Symantec does not know who is behind it and found no link to an existing malware family
  • Symantec described the AI targeting as ‘a new development that hasn’t previously been reported’

What happened

Commodity malware has started to treat AI coding tools as a store of valuable secrets. Symantec’s analysis of the newest Aoki samples found a list of AI-assistant files and tokens added to its usual theft list.

Why it matters

AI keys are sold and abused for “LLMjacking” (running models on a victim’s bill), and coding-agent tokens can open the repositories and pipelines they are connected to. The report was found two weeks late, through Symantec’s Oct 29 relay report.
