Over 12 million unique device identifiers (UDID), and related, personally-identifiable information, for iPhones, iPod touches, and iPads have reportedly been hacked from an FBI laptop using a Java vulnerability. AntiSec has released 1 million of the UDIDs as proof of the hack, along with a statement that includes the following:
UDIDs are used by developers to register devices with Apple's iTunes Connect so they can run beta versions of iOS and test ad-hoc versions of their apps prior to release. While some developers also used to use them to identify users and their devices, Apple has now disallowed that practice.
No accounts or passwords appear to have been compromised, so for users this is more of a privacy issue than a security issue. Any single piece of identifying information, be it a UDID number or a cell phone number, when combined with a sufficiently large pool of data and the right kind of analytics, can be used to create profiles and assess patterns.
AntiSec says they released the information to draw attention to what they claim is the FBI's collection of it.
