Renegade hacking collective Anonymous is today claiming one of its most audacious security breaches to date, saying that it has obtained over 12 million Apple Unique Device Identifiers (UDIDs) via an attack on an FBI agent's computer.
In a note, the group alleged to have posted more than a million of the UDIDs online, adding that it had launched the hack as part of its AntiSec campaign to expose the security flaws in corporate and government stored information. In this case, it said that it exploited the Atomic Reference Array vulnerability in Java on the agent's device.
Additionally, Anonymous said the attack was intended to draw attention to suspicions that the FBI was able to use the stored information to monitor US citizens.
"It seems quite clear nobody pays attention if you just come and say, 'Hey, [the] FBI is using your device details and information and who knows what they [are] experimenting with that.' Nobody will care," the group said in its post.
"12,000,000 identified and tracked iOS devices. Thanks FBI SSA Christropher Stangl," it tweeted.
Another possibility is that the group's latest hack is a form of retaliation for the FBI's recent arrest of Raynaldo Rivera, a reputed Lulz Sec member involved in the notorious attack on Sony Pictures. The two hackivist crews are loosely affiliated.
In the UK, Anonymous recently targeted a number of government websites – downing a public information portal run by the Ministry of Justice – in response to Britain's handling of the Julian Assange case.
