During installation, a heavily obfuscated code is executed. Exact behaviour unclear Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2025-07-test-package-avinav Reasons (based on the campaign): - obfuscation The OpenSSF Package Analysis project identified 'test-package-avinav' @ 0.0.1 (pypi) as malicious.

Which versions of test-package-avinav are malicious?

The following PyPI versions of test-package-avinav are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate test-package-avinav if I installed it?

test-package-avinav 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 test-package-avinav — how do I know if it already compromised me?

If test-package-avinav 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 test-package-avinav part of a known attack campaign?

Yes — test-package-avinav is associated with the 2025-07-test-package-avinav campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
