With this script, any user can get a response of the associated e-mail address as long as the SIM card number is provided in the request sent to the server. Since Ipad has a built-in AT&T network SIM card and each SIM card carries an authentication number which is ICC-IDS, when this number was sent to the website of AT&T, the website would return the email address corresponding to the number provided. By knowing 3G version of the iPad SIM card number, you can easily guess the other card number, in order to obtain a large number of user information.

Technical Changes and Improvements

What AT&T has done was to escalate the level of this incident to the highest level and turned off the feature of providing the E-mail address related with ICC-IDS. Meanwhile, the customers of AT&T were notified that their information was leaked due to the vulnerability.
