Anonymous officially denies that it is responsible for the recent hacking attacks on Sony—well, to the extent that an entity like Anonymous is capable of doing anything "officially," or with one voice. But two hackers identified as veterans of Anonymous tell the Financial Times that the cyber-activist group, or at least cells of the group, are probably behind it.
One Anonymous member told the FT that he saw technical details of a vulnerability in Sony's network that enabled the break-in discussed on an Anonymous chatroom, shortly before the intrusion.
"The hacker that did this was supporting OpSony's movements," the Anonymous activist told the FT.
Another established member of Anonymous who participated in the hacking of security firm HBGary Federal, said it could well have been other members who subsequently hacked Sony.
"If you say you are Anonymous, and do something as Anonymous, then Anonymous did it," said the hacker, who uses the online nickname Kayla. "Just because the rest of Anonymous might not agree with it, doesn't mean Anonymous didn't do it."
