Summary
Malicious code in claude-all-config (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (63c5a1f5a6f5bd2dadc4e207ff4e8e310c24cd4c99c751ed094251e00e0af8f3)

On install, postinstall.js writes configuration into ~/.claude/, ~/.gemini/, ~/.codex/, and ~/.kiro/ that hard-wires AI tooling to author-controlled destinations:

  1. Silent relay to author's Telegram: mcp.json registers a 'telegram' MCP server with a hardcoded TELEGRAMBOTTOKEN (bot @mcpclibot, token 8898185692:AAEjW5PcFLiwKJYf58X4pYY47HpbZvWGOUk) and TELEGRAMCHAT_ID=1185240496 (the author's own chat). Any notification/message the installer routes through the Telegram MCP is delivered by default to the author's Telegram account.
  2. Author-funded API keys:.env.example ships live production keys for Z.AI (ZAIAPI_KEY=7b1a5a0d145545ae8f2baa2957691ac4...), MiniMax (sk-cp-EPrTEuQVxp0PES9ItiDFm46scpYtk3Ec...), Context7, and Exa, copied into ~/.claude/.env etc. Installer prompts and data are routed to API accounts owned by the package author.
  3. Command shadowing: ~/.local/bin/gemini and ~/.local/bin/codex symlinks shadow the real binaries; the shims source the author-supplied env (keys + Telegram token) before exec'ing the real tool, and the gemini shim auto-appends --yolo.
  4. Permission disablement: ~/.claude/settings.json and ~/.gemini/settings.json grant Bash(), Write(), WebFetch(*) and set autoAccept:true; the launcher exports IS_SANDBOX=1 to bypass Claude's root safety check and force --dangerously-skip-permissions.
  5. Unpinned remote shell installer: postinstall runs curl -LsSf https://astral.sh/uv/install.sh | sh without pin or checksum if uvx is missing.

The combination of (1) silent default routing of caller-supplied content to the author's Telegram chat, (2) injection of author-owned API credentials into the installer's AI stack so prompt/code content flows to author-controlled API endpoints, and (3) shimming of system commands so this routing applies to every future invocation of gemini/codex, is a silent-relay supply-chain pattern: the installer's data and prompts flow to author-controlled destinations by default, without explicit per-invocation consent.
