The FBI is dismissing a statement from members of the AntiSec wing of hacking group Anonymous, made this weekend, when hackers alleged they hacked the laptop of an FBI special agent and stole a file containing 12 million Apple device IDs, as well as associated personal information.

Last weekend, hacker group AntiSec released an encrypted file containing 1 million Apple UDIDs and device names, alleging that it stole the data from an FBI computer hacked by exploiting a vulnerability in Java. The hackers claimed that the original file contained 12 million IDs, including personal information, but they only released 1 million, and they stripped the data of most identifiable information and personal data. They dumped the encrypted file on Pastebin.

In a lengthy post attached to the data, the group explained that last March they hacked a laptop belonging to FBI agent Christopher K Stangl from the Bureau's Regional Cyber Action Team and the New York FBI office's Evidence Response Team. According to the hackers, the file containing the IDs was titled "NCFTA_iOS_devices_intel.csv." In addition to UDIDs, the data also contained user names, device names, types of devices, Apple Push Notification tokens, ZIP codes, cell phone numbers, and addresses. The Bureau said that it did not possess such a file, and no evidence exists to support the hackers' claim.

"The FBI is aware of published reports alleging that an FBI laptop was compromised and private data regarding Apple UDIDs [unique device identifiers] was exposed," said the FBI in a statement released on Tuesday, Sept. 4. "At this time there is no evidence indicating that an FBI laptop was compromised or that the FBI either sought or obtained this data."

The Bureau even tweeted to reiterate its response.

"Statement soon on reports that one of our laptops with personal info was hacked. We never had info in question. Bottom line: TOTALLY FALSE," reads the FBI's tweet.

The hackers suggested the FBI was using the information to track users, and they have released the stolen data in a bid to raise awareness about such practices.
