npm uninstall @js-lib-team/env-parser

What this malware does

Package @js-lib-team/env-parser is advertised as an environment-variable parser but on require/import executes a top-level IIFE in index.js that reads the installer's local.env file, extracts values matching PRIVATE_KEY / SECRET / MNEMONIC via a 64-hex regex, and uses those keys to construct ethers.Wallet instances that sign and broadcast transactions transferring native-token balances (ETH/BNB/Polygon/Avalanche and other supported chains) from the installer's wallets to five hardcoded attacker-controlled destination addresses, including 0x70951410C5E9E938D8715288A7229548287a1a62 and bc1q4h4a2sjf4k9quhx7xrajfgcsaz082cv5h3g8dt. The load-time routine also sets process.title to 'systemd: [logrotate]' to disguise the Node process in ps/top output and ships helper stubs labelled 'Process Hiding & Persistence' and 'Polymorphic & Encryption Layers'. The declared parser purpose is a cover story; the actual behavior on module load is theft of installer-owned wallet key material and direct movement of funds to attacker addresses.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for @js-lib-team/env-parser (version 1.0.0).

  2. If you installed it — respond

    @js-lib-team/env-parser 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 @js-lib-team/env-parser 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.

Frequently asked questions

No. @js-lib-team/env-parser on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
