Which versions of vinted-mocked-apis are malicious?

The following PyPI versions of vinted-mocked-apis are flagged malicious: 99.0.0. Treat any of these as compromised.

How do I remediate vinted-mocked-apis if I installed it?

vinted-mocked-apis 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 vinted-mocked-apis — how do I know if it already compromised me?

If vinted-mocked-apis 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 vinted-mocked-apis part of a known attack campaign?

Yes — vinted-mocked-apis is associated with the GENERIC-standard-pypi-install-pentest 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 vinted-mocked-apis across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for vinted-mocked-apis (version 99.0.0).
