Hey all--Riot Smileyjoe here. Highjacking a top comment to get a little visibility. Also going to post as a reply to u/lestargonzaga 's original post.
Wanted to share with everyone the update that Garena just shared on lol.garena.ph and the League of Legends - Philippines Facebook page so everyone here can see it:
On July 9, 2:16 PM GMT+8, there was an unauthorized modification of the League of Legends PH client lobby where a certain javascript code was inserted. This code performs blockchain mining on affected computers, which consumes CPU resources from these computers. Apart from increased CPU usage, extensive analysis from our security engineers has determined that there is no other impact on affected computers. At July 11, 4:15 AM GMT+8, our security engineers have removed this javascript code and ensure that all users, including those who were previously affected, will no longer encounter this issue.
We treat security matters with utmost priority and sincerely apologize for this incident, and for the inconvenience you have experienced.
