For several hours early Thursday morning, the Deus Ex Web site, user forum, and Eidos.com were unreachable. For a brief period late Wednesday evening, the sites displayed a defacement banner that read Owned by Chippy1337″ (click screen shot at right for a larger version), along with several names and hacker handles of those supposedly responsible for the break-in.
KrebsOnSecurity.com obtained an archived copy of the attackers online chatter as they were covering their tracks from compromising the sites. A hacker using the alias ev0″ discusses having defaced the sites and downloading some 9,000 resumes from Eidos. ev0 and other hackers discuss leaking src, which may refer to source code for Deus Ex or other Eidos games. In a separate conversation, the hackers also say they have stolen information on at least 80,000 Deus Ex users and that they plan to release the data on file-sharing networks.
Neither Eidos nor its parent company Square Enix Co. could be immediately reached for comment. (This may not be the first time Eidos was breached: In a story I wrote earlier this year, I detailed how hackers on an underground criminal forum claimed to be selling access to Eidos customer database).
