(September 4, 2012) Hackers have dumped online the unique identification codes for one million Apple iPhones and iPads allegedly lifted from an FBI agent's laptop.

The leak, if genuine, proves Feds are walking around with data on at least 12 million iOS devices.

The 20-byte ID codes were, we're told, copied from a file extracted from the Dell notebook of a senior federal agent, who was tracking the activities of hacktivists in LulzSec, Anonymous and related groups.

Supervisor Special Agent Christopher Stangl's machine was compromised via a AtomicReferenceArray vulnerability in Java in March, the black hats claim.

Once his computer was infiltrated by the hackers, a file was allegedly seized containing 12 million device records that included Unique Device Identifiers (UDIDs), usernames and push notification tokens as well as a smaller number of names, mobile phone numbers, addresses and zip codes.
