Here’s how to check if your Apple device UDID has been compromised by the AntiSec leak

So it turns out that 1 million Apple devices had their UDIDs leaked by AntiSec, a group of hackers, who reportedly obtained a list of over 12 million UDIDs from an FBI agent’s laptop. 

TNW has put together a page to see if you were affected by this. Simply input your UDID into the form field to check it.

If you don’t know how to find your UDID, simply download a UDID emailer app. I used UDID Sender which you can download from the App Store here.

Update: Full report from Ars Technica, including a link to a survey if your UDID was found in the list. The purpose of the survey is to find out who leaked the UDIDs to the FBI.
