AT&T Inc said on Monday that it had fired an employee who gained access to customer information in August, possibly including Social Security and driver’s license numbers. According to a letter posted on the website of the Attorney General of Vermont on Oct. 1, the company said the person may have obtained Social Security numbers, driver’s license numbers and AT&T services customers.

Federal authorities have been notified regarding the incident, and the employee has since been fired, the carrier said.

The news follows breaches that include a massive cyberattack at JPMorgan Chase & Co, a theft involving Apple's iCloud and an alleged international computer hacking ring charged with stealing more than $100 million worth of software and data.
