There is a provlem going on now in the entire LoL SEA. Our LOL Client is being used as a Monero Mining. Ones we open our Client (PH), our CPU usage skyrockets to 90-100%. Our antiviruses blocks LoLclients and detects a ip address which is connected to CoinHive. Online hackers can penetrate to our systems. I wish that any Rioter would solve this issue.
