Hacking group Anonymous claims to have released a set of more than 1 million Apple Unique Device Identifiers (UDIDs) obtained from breaching the FBI.
The group indicated that the action was part of is AntiSec (Anti Security) campaign to steal and leak classified government and company information to expose security flaws.
Anonymous claims to have garnered over 12 million UDIDs, as well as associated personal information such as user names, device names, mobile phone numbers and addresses, according to US reports.
In a statement, Anonymous said it had obtained the data when it breached a mobile computer of an FBI special agent using the Atomic Reference Array vulnerability in Java.
Anonymous said it had published the UDID numbers to call attention to suspicions that the FBI used the information to track citizens.
“We have learnt it seems quite clear nobody pays attention if you just come and say hey, FBI is using your device details and info,” the group said in an online posting.
