Which versions of web-pool are malicious?

The following npm versions of web-pool are flagged malicious: 2.3.5. Treat any of these as compromised.

How do I remediate web-pool if I installed it?

Remove web-pool 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 web-pool part of a known attack campaign?

Yes — web-pool is associated with the IN-MAL-2026-005552 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 web-pool 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 web-pool and packages like it before any post-install script runs.

What this malware does

Requiring web-pool triggers middleware() to spawn a detached node lib/initializeCaller.js. That script base64-decodes a hardcoded endpoint (https://ipcheck-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df), POSTs the entire process.env (CI tokens, npm tokens, AWS_*, GITHUB_TOKEN, arbitrary secrets) to it, and executes the HTTP response body via new Function('require', response.data)(require) — granting the attacker arbitrary code execution under the installer's Node process. The C2 URL is hidden behind base64 inside a fake local process object that shadows Node's real process, an obfuscation pattern designed to defeat static URL scanning. The README masquerades as the pino logger (titled web-corn, badges and links point to npm pino and pinojs/pino), making this a typosquat lure with a malware loader as its only real behavior.
