AT&T Tells Users of ‘Organized and Systematic’ Hack Attempt
AT&T Inc. (T), the largest U.S. telephone company, notified customers of an effort by hackers to collect online account information.
“We recently detected an organized and systematic attempt to obtain information on a number of AT&T customer accounts, including yours,” AT&T said in an e-mail to customers. “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.”
AT&T said the hacking attempt used so-called auto script technology to “determine whether AT&T telephone numbers were linked to online AT&T accounts,” company spokesman Mark Siegel wrote in an e-mail. In a telephone interview, Siegel said that less than 1 percent of the Dallas-based company’s customers were affected.
“No accounts were breached and our investigation is ongoing to determine the source or intent of the attempt to gather this information,” Siegel wrote in the e-mail.
Earlier today, AT&T customers in the northeastern U.S. experienced a wireless data outage that was restored after a three-hour service disruption. AT&T says there was no connection between the two events.
Last year, AT&T was the target of hackers who managed to obtain the e-mail addresses of users of Apple Inc. (AAPL) iPads. At the time, hackers were able to collect the e-mail addresses from the auto-fill function on AT&T’s iPad customer logins. Siegel said there was also no connection to that hack.
The company says its focus on security and swift action helped identify the most recent hack attempt and alert customers quickly.
AT&T fell 1 percent to close at $28.36 in New York trading. The shares are down 3.5 percent this year.
