show moreCoordinated application-layer DDoS against git.mills.io (self-hosted Gitea), 2026-06-12 ~20:30-21:10 UTC. Deliberately expensive multi-label Gitea issue-search queries (/issues?type=all&state=closed&sort=...&labels=<multiple IDs>, ~60-113s CPU each) flooded the backend via proxy/hosting networks. ~36,700 source IPs, ~1 request per IP, identical TLS fingerprint (TLS1.3 0x1301) and one spoofed Chrome UA = single automated tool.
