Which versions of bs3 are malicious?

The following PyPI versions of bs3 are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate bs3 if I installed it?

Remove bs3 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 bs3 — how do I know if it already compromised me?

If bs3 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 bs3 part of a known attack campaign?

Yes — bs3 is associated with the RLMA-2024-03616, RLUA-2024-07898 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 bs3 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for bs3 (version 0.0.1).

Detect & block this

O3 blocks bs3-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
