AT&T Data Breach Investigation



Recently, AT&T announced a data breach of approximately 7.6 million current customers and approximately 65.4 million former account holders. The data compromised may include full names, email addresses, mailing addresses, phone numbers, dates of birth and AT&T account numbers, Social Security Numbers and four-digit passcodes (PINS). AT&T claims the impacted data is from 2019 or earlier, and denies the data was taken directly from AT&T.

We believe that this personally identifiable information was not adequately protected. This is especially true as to former subscribers (also known as legacy data), which AT&T should not retain.

If you were an AT&T customer since or before 2019 and received a notice from AT&T regarding the breach, you may have a legal claim entitling you to compensation.
