A PHP script posing as an image can be used to steal the IP addresses of the players connected that load up that image on their game client.

  • dead that bro took 5 attempts to write "callvote" LMAOOO

  • So this onky works if the attacker is in your team and starts a vote kick? So when you play five man with the boys, you are just fine?

  • Valve shits on its players. Neither the servers closed nor their players informed about it. Absolutely unworthy behavior for such a large company. Game and Steam permanently deleted.

  • so what? its just ip .. they cant do shit

  • Based gentleman playing the Ratchet and Clank 3 multiplayer lobby music.

  • Ayo, I have been playing CS2 for the past few days until I know about this now. I did witness some spam kicks in casual game and voted. So I am fucked basically right?

  • That explains why yesterday in my casual matches vote kick kept coming up a lot. I thought it was strange.
