What does the bloxypy malware do?

Attempting to use the module starts obfuscated code containing an infostealer Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2025-09-bloxypy Reasons (based on the campaign): - infostealer - obfuscation - action-hidden-in-lib-usage - infostealer:kiwi - exfiltration-browser-data This malicious package executes code obfuscated using Base64 encoding. It is designed to mimic the ro-py package.

Which versions of bloxypy are malicious?

The following PyPI versions of bloxypy are flagged malicious: 0.1.9. Treat any of these as compromised.

How do I remediate bloxypy if I installed it?

bloxypy 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 bloxypy — how do I know if it already compromised me?

If bloxypy 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 bloxypy part of a known attack campaign?

Yes — bloxypy is associated with the 2025-09-bloxypy 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 bloxypy across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for bloxypy (version 0.1.9).
