Which versions of @mastra/sentry are malicious?

The following npm versions of @mastra/sentry are flagged malicious: 1.1.4. Treat any of these as compromised.

How do I remediate @mastra/sentry if I installed it?

Remove @mastra/sentry 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 network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is @mastra/sentry part of a known attack campaign?

Yes — @mastra/sentry is associated with the GHSA-r8mf-3854-wvmf campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect @mastra/sentry in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking @mastra/sentry and packages like it before any post-install script runs.

What this malware does

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
