AT&T warns customers of scripted attack

According to a letter sent to customers by AT&T, attackers used automated scripts to determine if AT&T subscriber numbers were tied to online accounts. Calling the event organized and systematic, the letter expressed doubt that any customer information was accessed.

We recently detected an organized and systematic attempt to obtain information on a number of AT&T customer accounts, including yours... We do not believe that the perpetrators of this attack obtained access to your online account or any of the information contained in that account, the letter to customers stated.

AT&T spokesperson Mark Siegel said that less than one-percent of AT&Ts customers were affected, and the company is still investigating.

No accounts were breached and our investigation is ongoing to determine the source or intent of the attempt to gather this information, Siegel said.

Despite the lack of success, AT&T informed customers out of an abundance of caution. There were no further details on the nature of the scripts, or how they were detected, other than the fact they were attempting to link cell numbers to online accounts.
