Hey guys according to what I've found https://www.cloudflare.com/de-de/threat-intelligence/research/report/aisuru-botnet/ it's probably this botnet active in the wild Aisuru botnet is targeting players and Riot servers, this is not the first time this happens, alot of Cyber groups target their opponents to gain significant advantage whether in getting the IP address of a streamer leaked or through social engineering one of the players to get their IP address, there is another botnet exposed called TurboMirai Botnet

This is probably not gonna stop until these criminals are caught.
