Hacker group AntiSec claims that they have obtained over 12 million iOS Unique Device IDs (UDID) and more from owners of iOS devices. They decided to prove it by releasing 1,000,001 of those to the public.
“During the second week of March 2012, a Dell Vostro notebook, used by Supervisor Special Agent Christopher K. Stangl from FBI Regional Cyber Action Team and New York FBI Office Evidence Response Team was breached using the AtomicReferenceArray vulnerability on Java, during the shell session some files were downloaded from his Desktop folder one of them with the name of ‘NCFTA_iOS_devices_intel.csv’ turned to be a list of 12,367,232 Apple iOS devices including Unique Device Identifiers (UDID), user names, name of device, type of device, Apple Push Notification Service tokens, zipcodes, cellphone numbers, addresses, etc,”
It doesn’t seem they had all that much trouble getting the information. They’ve decided to release only a partial list, but it allows folks to find out if they’re being tracked by the FBI. The group also has names, addresses and cellphone numbers for some of those users, but has not released them.
