Security News > 2024 > July > Massive AT&T Hack Exposed ‘Nearly All’ Customer Phone Numbers

According to AT&T, the threat actor accessed phone call and text message records, including which phone numbers customers interacted with and, in some cases, cell site ID numbers.

AT&T first became aware of the attack on April 19 after "a threat actor claimed" to have accessed the data, according to AT&T's SEC filing about the incident.

As part of that disclosure, AT&T predicted that the April cyberattack was not "Reasonably likely to materially impact AT&T's financial condition or results of operations."

AT&T customers who manage business accounts can check whether their data was affected at myAT&T or the Premier business plan portal.

All customers, including business accounts and former customers, can see exactly what information was exposed about their phone number through a variety of options AT&T presents on its support page.
