Publisher 2K has confirmed that its customer support service has been hacked, advising users to change their passwords and install antivirus software. The hack comes as the most recent in a string of attacks that have affected major game companies like Rockstar Games and Blizzard. Rockstar Games' high-profile hacking earlier this week saw major leaks from the in-development Grand Theft Auto 6 with gameplay videos surfacing online. Now, the newest compromise from 2K could have a much more malicious effect on the online platform's users.
