The data includes the phone numbers that customers interacted with, AT&T said.
AT&T says that call and text records from almost all of its wireless customers were stolen in a hack earlier this year.
The carrier said on Friday that it learned in April that customer data had been «illegally downloaded» from its workspace on a third-party cloud platform.
The compromised data includes files containing AT&T records of calls and texts of «nearly all of AT&T’s cellular customers, customers of mobile virtual network operators (MVNOs) using AT&T’s wireless network, as well as AT&T’s landline customers who interacted with those cellular numbers between May 1, 2022 — October 31, 2022.
