Which versions of connector-bsb are malicious?

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

How do I remediate connector-bsb if I installed it?

Remove connector-bsb 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 activity or persistence.

I already installed connector-bsb — how do I know if it already compromised me?

If connector-bsb 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.

How do I find connector-bsb across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for connector-bsb (version 1.0.0).
