What this malware does

This package is a typosquat of the bitcoinjs-wallet ecosystem. Its index.js is a thin passthrough while the malicious behavior is in postinstall.js, which runs automatically on npm install. The postinstall script enumerates ~/.ssh, ~/.npmrc, ~/.gitconfig, Chrome/Chromium/Firefox profile paths (Cookies, Login Data, key4.db, logins.json), and a curated list of cryptocurrency wallet directories (.bitcoin,.ethereum,.metamask,.exodus,.electrum, and others). It also reads credential-shaped environment variables including NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, AWS_SECRET_ACCESS_KEY, PRIVATE_KEY, MNEMONIC, SEED_PHRASE, and ETHEREUM_PRIVATE_KEY. It shells out to npm whoami and git config --global user.email via child_process.execSync to tag the harvested data with the developer's identity. The collected profile is transmitted via two channels: a GET to api.telegram.org using a hardcoded bot token (7231970337) and chat_id, and a POST to /collect on the serveo tunnel host 40f955f39128bd79-178-249-214-24.serveousercontent.com. Exfiltration is delayed via setTimeout with a randomized 1500-3500 ms window and wrapped in an 'environment verification' cover-story comment to blend with normal install activity.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @zzzgenesis00/bitcoinjs-wallet (version 5.4.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @zzzgenesis00/bitcoinjs-wallet across your stack and pipelines.

  2. If you installed it — respond

    @zzzgenesis00/bitcoinjs-wallet is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If @zzzgenesis00/bitcoinjs-wallet was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks @zzzgenesis00/bitcoinjs-wallet before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions
