The following RubyGems versions of m8402v5qwf are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate m8402v5qwf if I installed it?

Remove m8402v5qwf 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 m8402v5qwf — how do I know if it already compromised me?

If m8402v5qwf 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 m8402v5qwf across my projects, lockfiles, and CI pipelines?
