Why disclose this publicly now, two years later ?
They uncovered the breach in April. From another article
“... cyber intruders accessed an AT&T workspace on a third-party cloud platform in April, downloading files containing customer call and text interactions between May 1 and October 31, 2022, as well as on January 2, 2023.
AT&T’s said it learned of the breach on April 19, but delayed disclosing it at the request of federal investigators. The company’s SEC disclosure says at least one individual has been detained by the authorities in connection with the breach.”
‘cause someone wants to use some data they been illegally collecting and doesn’t want anyone to get suspicious?
