UScellular, self-described as the fourth-largest wireless carrier in the US, has disclosed a data breach after the company's billing system was hacked in December 2021.

"On December 13, 2021, UScellular detected a data security incident in 'which unauthorized individuals illegally accessed our billing system and gained access to wireless customer accounts that contain personal information," the carrier explained.

"Information in customer accounts include name, address, PIN code and cellular telephone number(s) as well as information about wireless services including service plan, usage and billing statements," UScellular said.

"Upon discovery of the incident, UScellular immediately disconnected the computer accessed by the unauthorized individuals from the internet and requested immediate removal from the internet of the fraudulent websites used by the fraudsters as part of the scheme," UScellular added.

Impacted UScellular customers are advised to be on the lookout for targeted phishing scams using personal information stolen from the company's CRM systems.

This is the second data breach that hit UScellular in 2021 after hackers were also able to gain access to the carrier's CRM software in January 2021.
