U.S. Cellular, the fourth largest wireless carrier in America, with 4.9 million customers, has suffered a data breach. A few retail store employees were scammed into downloading a software onto their computer. The software allowed the attacker to access their computers remotely. Once the employees logged into the customer relationship management (CRM) system, the hackers gained access to these records.
While on the CRM system, the attackers were able to view customers’ account, including their name, address, PIN, cell phone numbers, service plan, and billing/usage statements.
USCellular believes the attack occurred on January 4, 2021.
