show moreThis address is taking part in a large-scale, distributed L7 DDoS against an online shop: automated requests to the shop's search, filter and sort pages — the most expensive pages to serve — sent with no referer and with no page asset loaded, so no browser is behind them. 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/2-scott | query: q=Famille-Gambler-Lumen-Patron-Plasma+RC-Speedster+Gravel+eRIDE | 2026-09-26 19:32 UTC
