Here's how to find out if your data was stolen in AT&T's massive hack

If you're one of AT&T's cellular customers, you can check your account to see if your data was compromised as part of the massive breach the telecom giant announced on Friday. 

If you were an AT&T customer between May 1, 2022 to Oct. 31, 2022, it's likely your data was involved, given that the company said "nearly all" its cellular customers' records were gathered by hackers during that time. The breach also includes records from Jan. 2, 2023 for a "very small number of customers," AT&T said.

But customers can check if their data was compromised by logging into their accounts, according to AT&T.
