The data of nearly all customers of the telecommunications giant AT&T was downloaded to a third-party platform in a security breach, the company said Friday…

Approximately 109 million customer accounts were impacted, according to AT&T, which said that it currently doesn’t believe that the data is publicly available.

“The data does not contain the content of calls or texts, personal information such as Social Security numbers, dates of birth, or other personally identifiable information,” AT&T said Friday.

The compromised data also doesn’t include some information typically seen in usage details, such as the time stamp of calls or texts, the company said, or customer names. AT&T, however, said that there are often ways using publicly available online tools to find the name associated with a specific telephone number…

AT&T identified the third-party platform as Snowflake and said that the incident was limited to an AT&T workspace on that cloud company’s platform and did not impact its network.
