Malicious package

@zzzgenesis00/ethers-walletnpm

@zzzgenesis00/ethers-wallet is a confirmed malicious npm package (MAL-2026-12031) that steals credentials and exfiltrates sensitive data (malicious version 6.13.5). 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/ethers-wallet

What this malware does

The package's postinstall.js runs automatically on npm install and harvests installer-owned secrets: it scrapes a curated env-var allowlist (NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY, PRIVATE_KEY, MNEMONIC, SEED_PHRASE, RPC API keys), enumerates ~/.ssh, reads ~/.npmrc and ~/.gitconfig, inventories Chrome/Firefox profile directories (cookies/login databases) and common crypto-wallet directories, and captures host identifiers via npm whoami and git config user.email. The collected profile is transmitted via HTTPS GET to api.telegram.org using a hardcoded bot token and chat_id, and POSTed as backup to a hardcoded serveo user-tunnel host (40f955f39128bd79-178-249-214-24.serveousercontent.com/collect). Package metadata (author ethers-io, homepage github.com/ethers-io/ethers-wallet) impersonates the ethers.js HD-wallet library while being published under the unrelated @zzzgenesis00 scope, luring developers with wallet material into installing the stealer.

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/ethers-wallet (version 6.13.5). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @zzzgenesis00/ethers-wallet across your stack and pipelines.

  2. If you installed it — respond

    @zzzgenesis00/ethers-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/ethers-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/ethers-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
