The FBI said on Tuesday denied that Hacker group AntiSec has released a list of 1 million Apple Unique Device Identifiers (UDIDs) that the hacker group claims it got from a laptop used by a FBI agent.

AntiSec yesterday claimed that the file found on the FBI laptop contained more than 12 million IDs that included personal information such as user names, push notification tokens, device names, cellphone numbers, addresses and zip codes.

"At this time there is no evidence indicating that an FBI laptop was compromised or that the FBI either sought or obtained this data," an FBI spokesman said in a statement.

All Apple devices are assigned the 40-character-long UDIDs, which are usually used by developers who want to test their apps. 

Antisec said that while hacking the laptop it accessed over 12 million UDIDs, with details like user names, device names, notification tokens, cell phone numbers and addresses. 

"There you have. 1,000,001 Apple Devices UDIDs linking to their users and their APNS tokens. The original file contained around 12,000,000 devices. we decided a million would be enough to release. we trimmed out other personal data as, full names, cell numbers, addresses, zipcodes, etc. Not all devices have the same amount of personal data linked. Some devices contained lot of info. Others no more than zipcodes or almost anything. we left those main columns we consider enough to help a significant amount of users to look if their devices are listed there or not. the DevTokens are included for those mobile hackers who could figure out some use from the dataset", it said in a statement.  

"For the last few years we have broke into systems belonging to Governments and big corporations just to find out they are spending millions of tax dollars to spy on their citizens. They work to discredit dissenting voices. They pay their friends for overpriced and insecure networks and services," read the statement.
