Which versions of mastraqqq are malicious?

The following npm versions of mastraqqq are flagged malicious: 1.13.1. Treat any of these as compromised.

How do I remediate mastraqqq if I installed it?

Remove mastraqqq 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 mastraqqq part of a known attack campaign?

Yes — mastraqqq is associated with the IN-MAL-2026-006808 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 mastraqqq 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 mastraqqq and packages like it before any post-install script runs.

What this malware does

Package is published as mastraqqq but bundles a verbatim clone of the legitimate mastra CLI: the embedded package metadata declares name: "mastra", version: "1.13.0" with Mastra's homepage and repository, and the README is the upstream Mastra CLI README. The npm-published manifest under the mastraqqq name (a 3-character-suffix edit of mastra) adds a single unrelated runtime dependency, caspian-day-js@^1.11.22, which is never imported anywhere in the bundled dist/ output. Installing mastraqqq therefore silently pulls caspian-day-js — an attacker-chosen package whose contents are outside this tarball — into the consumer's install graph under cover of a Mastra impersonation. The combination of impersonation (identical bundled name/version/README/code) plus an unexplained, never-referenced extra dependency is the canonical namespace-abuse delivery shape: the lure is the typosquat, the payload arrives via the smuggled dep.
