An apparent hack attack has taken place on the EA servers. Players were reporting the "top 6 players" by score were not the regular top players. The hack is also visible in the bf2s.com website by viewing the leaderboard. The hackers are sporting a clan tag of MSX, which is known as MS Security or a variant there of. The move by the MSX members looks like the clan is trying to prove the punk buster utility and the anti-hacking software of the Battlefield2 game is still unable to catch and prevent hackers. This comes as a negative blow to players of the Battlefield2 community, because we continuously strive to play a fair game.
