AntiSec published 1,000,001 iPhone UDID codes… Did they publish yours?

AntiSec has released over a million iPhone device IDs that they claimed they obtained while ‘auditing’ the FBI.

The report on is rather hard to read, but includes this quote explaining where the files came from:

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. the personal details fields referring to people appears many times empty leaving the whole list incompleted on many parts. no other file on the same folder makes mention about this list or its purpose.

AntiSec published the UDID numbers in order to make a point that they belive the FBI is tracking citizens. The team removed much of the personal data but left enough that if your device is one of the million, your name will likely be attached as well.

This isn’t a small list. The Next Web has a tool that will help you search for your UDID, if for some reason you don’t have an app that can read and search a CSV file. (You could of course download OpenOffice.) I am not sure I would paste my UDID into a non-secure text field on a website, but if you’re interested here is the link: UDID Check.
