Which versions of @zzzgenesis00/hdkey-wallet are malicious?

The following npm versions of @zzzgenesis00/hdkey-wallet are flagged malicious: 2.1.0. Treat any of these as compromised.

How do I remediate @zzzgenesis00/hdkey-wallet if I installed it?

@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.

I already installed @zzzgenesis00/hdkey-wallet — how do I know if it already compromised me?

If @zzzgenesis00/hdkey-wallet was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is @zzzgenesis00/hdkey-wallet part of a known attack campaign?

Yes — @zzzgenesis00/hdkey-wallet is associated with the IN-MAL-2026-011342 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @zzzgenesis00/hdkey-wallet across my projects, lockfiles, and CI pipelines?

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'.
