How does GitHub actively prevent and scan for malware code pushes?

I'm curious about how GitHub handles malware. Does the platform automatically scan code for malware files during a push, or does it mostly rely on user reports to take down malicious repositories?
I know about features like Secret Scanning and Dependabot, but I'd love to know more about how GitHub catches actual malware without accidentally blocking legitimate cybersecurity research.
Thanks!

Hi!
GitHub doesn't publicly document every detail of how it detects malware, but it isn't based solely on user reports.

GitHub uses a combination of automated systems and manual review to identify repositories that may contain malicious content. At the same time, they try to distinguish between software that is intentionally malicious and legitimate security research, proof-of-concept code, or educational projects, since those can sometimes look similar.

If a repository is flagged, GitHub may review it to determine whether it violates their policies before taking action. User reports are also an important part of the process, especially if someone discovers a repository that appears to be distributing malware or being used for malicious purposes.

So, in short:

• GitHub uses automated detection in addition to user reports.
• Not all code that resembles malware is removed—context matters, particularly for cybersecurity research and educational repositories.
• If you come across a repository you believe is malicious or violates GitHub's policies, you can report it so GitHub can investigate.

Hope this helps!
