Which versions of quasitonnts are malicious?

The following PyPI versions of quasitonnts are flagged malicious: 0.1.0. Treat any of these as compromised.

How do I remediate quasitonnts if I installed it?

quasitonnts is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed quasitonnts — how do I know if it already compromised me?

If quasitonnts 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 quasitonnts part of a known attack campaign?

Yes — quasitonnts is associated with the 2026-10-emberlytts 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 quasitonnts across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for quasitonnts (version 0.1.0).

What this malware does

The package belongs to a series of packages falsely advertising 'audio-analysis profiles' loader. In fact, the only purpose is to execute remote code, but the URL is not embedded in the package. It is likely a continuation of the coin-mining campaign 2026-10-voxeval which used similar wording.
