The FBI is saying that claims made by the AntiSec hacking group on Tuesday are false. The AntiSec group, which Tweets under the account @AnonymousIRC, claims that it breached an agency-owned computer and stole a database said to contain some 12 million unique device ID (UDID) numbers for iPhones and iPads around the world.

However, the Bureau says that the FBI computer from which the data was supposedly stolen was never hacked, reports AllThingsD. What’s more, as per this report, the agency said that “it never gathered the information in the first place.”

In a statement, an FBI spokesperson stated, “The FBI is aware of published reports alleging that an FBI laptop was compromised and private data regarding Apple (News - Alert) UDIDs was exposed. At this time there is no evidence indicating that an FBI laptop was compromised or that the FBI either sought or obtained this data.”

Meanwhile, the report indicates that AntiSec, also known as LulzSec or Anonymous, posted a message on Pastebin on Tuesday that claimed that it had stolen a list of millions of UDID numbers and related names and other information for some 12 million Apple-made iOS devices, including iPhones, iPads and iPod touches. The hackers claim that they stole them from a notebook computer belonging to an FBI employee.

According to the report, the hacking group is making this claim, which is only an unverified claim, to sound an alarm that the top American law enforcement agency is creating a list of owners of such devices for uncertain purpose.

However, the law enforcement agency is not buying this story and is raising further questions about the origins of the document that AntiSec released on Tuesday.

Interestingly, the report shows that this is not the first time that AntiSec has made such claims about its abilities. Last summer, “it made a lot of noise about a bunch of documents from NATO, which it portrayed as both important and sensitive, but which after a little scrutiny turned out to be neither.”
