Which versions of m8403v2tew are malicious?

The following RubyGems versions of m8403v2tew are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate m8403v2tew if I installed it?

Remove m8403v2tew 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 m8403v2tew — how do I know if it already compromised me?

If m8403v2tew 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 m8403v2tew part of a known attack campaign?

Yes — m8403v2tew is associated with the RLMA-2026-02725, RLUA-2026-08573 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 m8403v2tew across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for m8403v2tew (version 0.0.1).
