Which versions of flow-lending are malicious?

The following npm versions of flow-lending are flagged malicious: 9.9.9. Treat any of these as compromised.

How do I remediate flow-lending if I installed it?

Remove flow-lending 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 flow-lending part of a known attack campaign?

Yes — flow-lending is associated with the IN-MAL-2026-006611, IN-MAL-2026-006612 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 flow-lending 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 flow-lending and packages like it before any post-install script runs.

What this malware does

On npm install, the package's preinstall lifecycle hook executes index.js, which collects host identity (hostname, username, cwd) and enumerates process.env, filtering keys against the regex /key|seed|secret|token|private|mnemonic|password|blockfrost|redis|telegram|batcher/i. The collected JSON is POSTed over HTTPS to a hardcoded bare IP destination (https://2.25.140.71:8443/surflending/npm-confusion). The package provides no legitimate functionality; the path component 'surflending/npm-confusion' and the 9.9.9 version (a version-bump pattern used to win dependency-confusion resolution) indicate a directed dependency-confusion attack against an internal Cardano/SundaeSwap-related package name. Any installer with wallet-related secrets in environment variables (mnemonics, private keys, blockfrost tokens, telegram bot tokens, redis credentials, batcher keys) loses them at install time.
