This is the best summary I could come up with:

AT&T today said a breach on a third-party cloud platform exposed the call and text records of nearly all its cellular customers.

As previously reported, Snowflake was compromised by a group that obtained login credentials through information-stealing malware.

"In April, AT&T learned that customer data was illegally downloaded from our workspace on a third-party cloud platform," AT&T announced today.

The carrier said the breach does not include Social Security numbers, dates of birth, other personally identifiable information, or the time stamps for calls and texts.

Shortly after identifying a potential breach to customer data and before making its materiality decision, AT&T contacted the FBI to report the incident.

An AT&T spokesperson told Ars that the Snowflake breach is unrelated to another recent leak involving the data of 73 million current and former subscribers.
