One million Apple UDIDs (Universal Device IDs) were released to the public today, along with Notification Center tokens, device names, and device IDs, and while none of the data is personal information, it can potentially be tied back to device owners, names, and addresses.


According to Antisec, the group that released the data, the one million is just part of over 12 million UDIDs they obtained from an FBI-owned laptop compromised in March 2012. The total dump reportedly also contains names, addresses, cellphone numbers, and other information about the device owners.

Unfortunately, if you own an Apple device, there's nothing you can really do at this point. You can't just change your UDID the way you can change a password. There are sites that let you search the 1 million dump to see if your UDID is in the list, but the safest and most surefire method is to download the nearly 90MB text file yourself from the links provided at Pastebin and check for your UDID with a simple Ctrl+F (Cmd+F on Mac). Also, even if your device isn't in the list, it could be in the other 11 million.


To find your phone's UDID:

Plug your device into your computer. Launch iTunes and select your device in the sidebar. Where you see your device's name, capacity, software version, and serial number, click on the serial number. This will toggle the display of your device's UDID.

It's unclear what if anything Apple (or the FBI for that matter) will say or do about the leak, or what a malicious party could do with the information, but for now it's a good reminder to keep your computers secure and malware free.
