In March 2024, tens of millions of records allegedly breached from AT&T were posted to a popular hacking forum. Dating back to August 2021, the data was originally posted for sale before later being freely released.

The incident exposed names, email and physical addresses, dates of birth, phone numbers and US social security numbers.
