Exploit: Credential Compromise
US Cellular: Mobile Phone Company
Risk to Small Business: 1.379 = Extreme
USCellular, the fourth largest mobile network in the US, has suffered a data breach after a successful malware attack. Hackers used malicious code disguised as a routine software update to gain access to systems including its Customer Relationship Management (CRM) and client records. This is not USCellular’s first time at this rodeo – the company has had consistent information security problems.
Individual Risk: 1.321 = Extreme
USCellular advised customers that their account records including name, address, PIN code, and cellular telephone numbers(s) as well as information about the customer’s wireless services including service plan, usage and billing statements, personal information, PIN code, service plan, and billing statements might have been compromised. However, data such as social security numbers and credit card information remained inaccessible to the hackers. Clients should be wary of spear phishing, business email compromise and identity theft using this information.
Customers Impacted: 4.9 million
