Each participating address sends only one or two such requests, but we count them by the million: a botnet, compromised devices, or abused proxies. The address is blocked. An investigation into what exactly sends these requests from your network (malware, an open proxy, a rented device) would help stop the attack at its source. \| path: /marque/8-orbea \| query: q=Famille-Kemen+ADV-Orca-Terra-Wild/Capacit%C3%A9+batterie-750+Wh \| 2026-09-26 22:34 UTC show less	DDoS Attack Web App Attack
