Malicious package

@zzzgenesis00/hdkey-walletnpm

@zzzgenesis00/hdkey-wallet is a confirmed malicious npm package (MAL-2026-11531) that steals credentials and exfiltrates sensitive data (malicious version 2.1.0). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @zzzgenesis00/hdkey-wallet

What this malware does

On npm install, scripts.postinstall executes postinstall.js which harvests installer-side secrets and host reconnaissance and transmits them to attacker-controlled destinations. Collected data includes: hostname, username, homedir, platform, arch, Node version, and cwd; contents/metadata of ~/.ssh, ~/.npmrc, and ~/.gitconfig; browser credential store paths (Chrome/Firefox cookies, login data, key4.db); presence of wallet directories (.bitcoin,.ethereum,.solana,.metamask,.exodus,.electrum,.tron, etc.); and roughly 30 credential-shaped environment variables including NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, PRIVATE_KEY, MNEMONIC, and SEED_PHRASE. The aggregated payload is sent to api.telegram.org via a hardcoded bot token and chat id, with a secondary POST channel to 40f955f39128bd79-178-249-214-24.serveousercontent.com/collect. The package is published under the unrelated @zzzgenesis00 scope while its metadata impersonates the cryptocoinjs maintainer and points its homepage at github.com/cryptocoinjs/hdkey-wallet; identifiers in the postinstall are obfuscated (_wgw, _ddo, _bkv, _cp, _ht, _tk, _ch) and framed with a cover comment describing 'postinstall environment verification'.

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/hdkey-wallet (version 2.1.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @zzzgenesis00/hdkey-wallet across your stack and pipelines.

  2. If you installed it — respond

    @zzzgenesis00/hdkey-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/hdkey-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/hdkey-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

No. @zzzgenesis00/hdkey-wallet on npm has been identified as a malicious package (version 2.1.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
