What does the website-scanner malware do?

The obfuscated code in setup.py on installation collects information about the system (all possible about hardware, available resources, IP, names, etc.) and sends to a telegram webhook. Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2024-09-website-scanner Reasons (based on the campaign): - exfiltration-generic - obfuscation - A Telegram webhook is used to send collected data. The OpenSSF Package Analysis project identified 'website-scanner' @ 1.0.0 (pypi) as malicious. It is considered malicious because: - The package communicates with a domain associated with malicious activity.

Which versions of website-scanner are malicious?

The following PyPI versions of website-scanner are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate website-scanner if I installed it?

website-scanner 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 website-scanner — how do I know if it already compromised me?

If website-scanner 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 website-scanner part of a known attack campaign?

Yes — website-scanner is associated with the 2024-09-website-scanner 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 website-scanner across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for website-scanner (version 1.0.0).
