Yesterday, news broke that the hacking group AntiSec published a million UDIDs from an alleged trove of twelve million device IDs claimed to have been stolen from a laptop belonging to an FBI agent. Even though the hackers had removed some of the identifiable information from the list, your UDID might be exposed out in the wild, along with 999,999 other IDs posted on the web.
And why would you want to know if your UDID is out there for everyone to see? Good question. Your UDID uniquely identifies your device and expert hackers could use it to glean all sorts of information from other data associated with your UDID.
Yeah, it's a privacy catastrophe, one that might potentially even lead to identity theft. Perhaps even more important than that, wouldn't you like to know if your device is on the FBI's watch list?
