Apple's Worst Security Breach: 114,000 iPad Owners Exposed
OuchGoatse Security obtained its data through a script on AT&T's website, accessible to anyone on the internet. When provided with an ICC-ID as part of an HTTP request, the script would return the associated email address, in what was apparently intended to be an AJAX-style response within a Web application. The security researchers were able to guess a large swath of ICC-IDs by looking at known iPad 3G ICC-IDs, some of which are shown in pictures posted by gadget enthusiasts to Flickr and other internet sites, and which can also be obtained through friendly associates who own iPads and are willing to share their information, available within the iPad "Settings" application.
To make AT&T's servers respond, the security group merely had to send an iPad-style "User agent" header in their Web request. Such header identify users' browser types to websites.
