AT&T says hack attempt affected up to 1 million customers

AT&T on Monday acknowledged an organized attempt to hack information on as many as 1 million AT&T wireless customer accounts, but the company said no accounts were breached.

A spokesman said the hackers appear to have used auto-script technology to find whether AT&T telephone numbers were linked to online AT&T accounts. He didn’t elaborate, but said an investigation is continuing.

The spokesman said fewer than 1 percent of AT&T’s 100.7 million wireless subscribers were contacted by hackers through email, a number that could mean about 1 million customers were affected.

“Our investigation is ongoing to determine the source or intent of the attempt to gather this information,” AT&T spokesman Mark Siegel said in an email.

He said the AT&T account holders were advised of the attempt “out of an abundance of caution.”
