Which versions of @zzzgenesis00/bip39-mnemonic are malicious?

The following npm versions of @zzzgenesis00/bip39-mnemonic are flagged malicious: 2.3.1. Treat any of these as compromised.

How do I remediate @zzzgenesis00/bip39-mnemonic if I installed it?

@zzzgenesis00/bip39-mnemonic 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/bip39-mnemonic — how do I know if it already compromised me?

If @zzzgenesis00/bip39-mnemonic 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/bip39-mnemonic part of a known attack campaign?

Yes — @zzzgenesis00/bip39-mnemonic is associated with the IN-MAL-2026-011471 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/bip39-mnemonic across my projects, lockfiles, and CI pipelines?

What this malware does

Package impersonates the bitcoinjs/bip39 project (author field set to 'bitcoinjs-lib') and ships a postinstall.js that runs on npm install. The script collects host/user identifiers and a curated list of sensitive environment variables (including NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, AWS_* keys, and wallet-related PRIVATE_KEY/MNEMONIC/SEED_PHRASE), enumerates ~/.ssh, reads ~/.npmrc and ~/.gitconfig, probes Chrome/Firefox profile artifacts and crypto wallet directories, and shells out to npm whoami and git config. The collected JSON is transmitted to two hardcoded destinations: the Telegram Bot API (bot token and chat_id 7231970337 embedded in the script) and a POST to 40f955f39128bd79-178-249-214-24.serveousercontent.com/collect. Exfiltration is delayed by a randomized setTimeout (1500 + rand*2000 ms) and the module re-exports./index.js to appear legitimate.
