If you’re worried that you might own one of the 1 million Apple devices that have had their UDIDs leaked by AntiSec, reportedly from a breach of an FBI agent’s laptop, our rockstar tech team has put together a tool to help you check. AntiSec claimed on Tuesday that it had culled 12 million device IDs, along with accompanying personal information, from the FBI in March of this year. The hacker group then leaked 1 million of them, saying it had removed some of the identifiable information from the list, while leaving enough for users to see if their device was leaked.
