This is the best summary I could come up with:

Additionally, AT&T said that for an undisclosed subset of its records, one or more cell site identification numbers linked to the calls and texts were also exposed.

The FBI said AT&T reached out shortly after learning about the hack, but the agency wanted to review the data for potential national security risks.

At that time, AT&T said personal information such as Social Security numbers on 73 million current and former customers was released onto the dark web.

In the new incident, AT&T told CNN it learned in April that customer data was illegally downloaded from its workspace on Snowflake, a third-party cloud platform.

Brad Jones, chief information security officer at Snowflake, told CNN in a separate statement that the company has not found evidence this activity was “caused by a vulnerability, misconfiguration or breach of Snowflake’s platform.” Jones said this has been verified by investigations by third-party cybersecurity experts at Mandiant and CrowdStroke.

The company said it’s cooperating with law enforcement’s efforts to apprehend those responsible and understands at least one person has already been arrested.
