UPS announced last week that malware discovered on computer systems at 51 stores compromised consumer information, exposing names, postal addresses, payment card information and email addresses.
The intrusion makes UPS the latest retailer among major names like Target and Michaels that have experienced a security breach.
According to the company, the U.S. Department of Homeland Security and Secret Service notified the company of a previously unknown malware threat. An investigation of The UPS Store systems found that stores in 24 states—approximately one percent of its locations—were affected by the malware.
Tim Davis, the president of The UPS Store, apologized in a company statement, saying UPS has “deployed extensive resources to quickly address and eliminate” the threat. So far, the company has not detected any evidence of fraud.
