The FBI is denying any involvement in a
list of leaked iOS UDIDs, according to official statements. "The FBI is aware of published reports alleging that an FBI laptop was compromised and private data regarding Apple UDIDs was exposed," the agency
tells AllThingsD. "At this time there is no evidence indicating that an FBI laptop was compromised or that the FBI either sought or obtained this data."
Although that statement is relatively ambiguous, the FBI is more explicit on an official Twitter feed. "Statement soon on reports that one of our laptops with personal info was hacked. We never had info in question. Bottom Line: TOTALLY FALSE," it
claims. The group that published the UDIDs, AntiSec, has said that it pulled the data from a computer belonging to Supervisor Special Agent Christopher K. Stangl, of the FBI Regional Cyber Action Team and New York FBI Office Evidence Response Team.
If the list isn't from an FBI computer however, it's unclear where it came from. At least some of the UDIDs are believed to be real; they may have been pulled from one or more app developers. AntiSec itself
says that "People whose UDID was on the list released by AntiSec might want to compare their installed apps. A common culprit might be found." The group has also reacted to the FBI's position. "Also, before you deny too much: Remember we're sitting on 3TB additional data. We have not even started," it says, referring to an
announcement made earlier this year by a related group, LulzSec.
