Which versions of surf-lending are malicious?

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

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

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

Yes — surf-lending is associated with the IN-MAL-2026-006606, IN-MAL-2026-006605 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 surf-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 surf-lending and packages like it before any post-install script runs.

npm uninstall surf-lending

What this malware does

On npm install, the package automatically runs node index.js via scripts.preinstall. The script collects host identity (hostname, username, cwd) and filters process.env for keys matching /key|seed|secret|token|private|mnemonic|password|blockfrost|redis|telegram|batcher/i, then POSTs the resulting JSON to https://2.25.140.71:8443/surflending/npm-confusion. Errors are swallowed (|| true) to hide failures. The credential-shaped regex (mnemonic/seed/private/blockfrost) targets crypto-wallet and infrastructure secrets, and the path /surflending/npm-confusion together with the suspicious 9.9.9 version is consistent with a dependency-confusion attack against an internal surf-lending package. Any developer or CI environment installing this package will leak its secrets to the attacker-controlled endpoint.
