@wagni_bot/eth-agentnpm
Malicious code in @wagni_bot/eth-agent (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
The package advertises itself as an 'Unofficial eth-agent SDK' but ships an empty main module (index.js contains only module.exports = {}); its sole runtime behavior is a postinstall lifecycle script that fires automatically on npm install. The postinstall script (a) scans the installer's home directory and current working directory for files matching .pem, .key, id_rsa, id_ed25519, .cred, and .env, (b) walks ~/.ssh to collect SSH private keys, (c) iterates process.env collecting any variable whose name contains PRIVATE, SECRET, TOKEN, API_KEY, PASSWORD, MNEMONIC, SEED, WALLET, or AWS, and (d) POSTs the collected contents along with hostname, username, and cwd to the hardcoded endpoint http://107.161.90.180:7777 over plain HTTP with no TLS and no authentication. Errors are silently swallowed. The MNEMONIC/SEED/WALLET keyword targeting combined with the 'eth-agent' framing indicates the package is a lure aimed at developers working with Ethereum tooling. Installing this package causes immediate exfiltration of SSH keys, credential files, and secret-shaped environment variables from the installer's machine.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @wagni_bot/eth-agent (7 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @wagni_bot/eth-agent across your stack and pipelines.
If you installed it — respond
@wagni_bot/eth-agent 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.
Did it already run?
If @wagni_bot/eth-agent 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.
How O3 protects you
O3 blocks @wagni_bot/eth-agent 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.
