NEW YORK, March 30. /TASS/. Personal data of 73 million subscribers of one of US’s largest cell phone carrier got leaked to the darknet, the company announced.

"AT&T has launched a robust investigation supported by internal and external cybersecurity experts. Based on our preliminary analysis, the data set appears to be from 2019 or earlier, impacting approximately 7.6 million current AT&T account holders and approximately 65.4 million former account holders," the carrier said in its statement.

The leaked information, which includes names, and social security numbers, got leaked to the darknet about two weeks ago, but the leak source has not been discovered yet. The company claimed that the incident has not affected its operation in any way so far.

A major disruption occurred in the AT&T operation in February, which was investigated by the Cybersecurity and Infrastructure Security Agency (CISA), together with the provider itself and the Federal Communications Commission (FCC).
