“AT&T is informing customers about a data breach at a vendor’s system that allowed threat actors to gain access to AT&T’s Customer Proprietary Network Information (CPNI). “
“The incident came to light after customers posted the email communication from AT&T on community forums to know if it was legitimate or email fraud. “
“Approximately nine million customers’ CPNI was accessed by the threat actors, according to a statement given by the company to Bleeping Computer. “
“Some impacted customers also had exposure of past due amount, monthly payment amount, and various monthly charges and/or minutes used, AT&T told the publication adding that the information was several years old. The data exposed mostly related to device upgrade eligibility and did not affect the company systems. “
