Which versions of janus-ft are malicious?

The following npm versions of janus-ft are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate janus-ft if I installed it?

Remove janus-ft from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is janus-ft part of a known attack campaign?

Yes — janus-ft is associated with the IN-MAL-2026-005399 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect janus-ft in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking janus-ft and packages like it before any post-install script runs.

What this malware does

On npm install, the package's postinstall.js script harvests installer-side secrets and ships them to a hardcoded bare-IP C2 endpoint. Specifically, it (1) collects hostname, username, and cwd; (2) iterates process.env and selects keys matching the regex /KEY|SECRET|TOKEN|PRIVATE|MNEMONIC|PASSWORD|RPC|ALCHEMY|INFURA|DATABASE|WALLET/i; (3) reads.env from cwd, parent directories, and the user's home directory; (4) reads ~/.npmrc (leaking npm auth tokens that enable further supply-chain compromise) and ~/.config/ipor-fusion/config.json (targeting users of the IPOR Fusion DeFi protocol); and (5) POSTs the bundled payload to https://193.203.169.109:8443/c/janus-ft with TLS verification disabled (rejectUnauthorized:false). The package's main entry (index.js) is module.exports = {}; — it provides no actual functionality, confirming the package exists solely to execute the credential-harvesting payload at install time. The targeted read of ipor-fusion config plus the blockchain-developer-oriented env keyword list (MNEMONIC, PRIVATE, WALLET, ALCHEMY, INFURA) indicate this is a targeted attack on DeFi/blockchain developers.
