Apple Insider posted a story that hackers from AntiSec on Tuesday claim to have leaked 1,000,001 iPhone and iPad identifiers the group allegedly obtained from a hacked FBI laptop holding over 12 million such Apple device IDs and corresponding personal information.

According to AntiSec, the unique device identifiers (UDID) of 12,367,232 Apple iPhones and iPads were discovered and lifted during the breach of an FBI agent's notebook, reports The Next Web. UDIDs are unique 40-character codes assigned to iDevices with cellular connectivity, their primary use being app registration and tracking by developers.
