NEW YORK (AP) — The theft of sensitive information belonging to millions of AT&T’s current and former customers has been recently discovered online. In a weekend announcement addressing the data breach, AT&T said that a dataset found on the dark web contains information including some Social Security numbers and passcodes for about 7.6 million current account holders and 65.4 million former account holders. Whether the data originated from AT&T or one of its vendors is still unknown. The Dallas-based company added that it had launched an investigation into the incident. AT&T has also begun notifying customers whose personal information was compromised.
