14 DAY TRIAL // A large number of Activision-published gaming sites such as Call of Duty, X-Men Origins: Wolverine, Spider-Man: Edge of Time, Transformers: Fall of Cybertron, Prototype 2, The Quantum of Solace, DJ Hero 2 and Guitar Hero were hacked by a Turkish hacker collective called GrayHatz.
The Hacker News reports that a studio owned by Activision, Infinity Ward, was also hacked and defaced to display the hackers' logo. The group didn’t leave any clues to reveal their reasons for hacking the sites.
The breach didn’t affect the main pages, the websites working normally at the time, instead they defaced pages hosted on the cdn subdomain of each site.
At the time of writing most of the sites still display the defacement pages, but hopefully the hackers didn’t manage to access any customer information.
I would think that all the pre-order information is safely stored in a secure, separate system that’s much better protected than the public sites.
