In response to AntiSec's recent publication of a million Apple Unique Device Identifiers (UDIDs) allegedly stolen from an FBI laptop, both Apple and the FBI have denied ever sharing such data.

In a statement released earlier this week, the FBI said, "The FBI is aware of published reports alleging that an FBI laptop was compromised and private data regarding Apple 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."

Soon after, Apple said essentially the same thing to AllThingsD's John Paczkowski. "The FBI has not requested this information from Apple, nor have we provided it to the FBI or any organization. Additionally, with iOS 6 we introduced a new set of APIs meant to replace the use of the UDID and will soon be banning the use of UDID,' Apple spokeswoman Natalie Kerris told AllThingsD," Paczkowski writes.

"The FBI statement puts the ball back in AntiSec's court," writes PCWorld's Tony Bradley. "One side or the other isn't being completely honest here. AntiSec does seem to be in possession of vast quantity of Apple device ID data. The question is, if the data didn't come from a hacked FBI laptop, where did the information come from and how did AntiSec acquire it?"

"When AntiSec first posted its purported findings, the group noted the leaked UDIDs had varying amounts of associated personal data, ranging from zip codes to more comprehensive datasets like full names and addresses," writes AppleInsider's Mikey Campbell. "UDID codes are available to app developers, however access is limited and doesn't usually include personal information."
