Questions about github.com

Is github.com safe?
The scan of github.com on 21 Aug 2026 reached no verdict either way (score -6). Too little was captured to judge it, which is an unknown rather than a pass.
What malware is associated with github.com?
3 analysed samples communicate with this URL.
How was github.com checked?
A static pass resolved DNS, captured TLS and headers and followed the redirect chain, and where the fast tier allows, a headless browser rendered the page and recorded every request. Egress is SSRF-locked. Signatures that matched only page text are weighted far below one that matched a served file, because a page documenting malware matches the same rules.
