Which versions of web3-pu are malicious?

The following PyPI versions of web3-pu are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate web3-pu if I installed it?

web3-pu 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.

I already installed web3-pu — how do I know if it already compromised me?

If web3-pu was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is web3-pu part of a known attack campaign?

Yes — web3-pu is associated with the RLMA-2024-09505, funcaptcha-ru campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find web3-pu across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for web3-pu (version 1.0.0).
