What can brown do for you? Possibly put your name, home address, email address and payment card details into the hands of hackers, not unlike a slew of other major retailers to fall victim to cyber criminals in recent days.

The Atlanta-based shipping giant's The UPS Store chainrevealedyesterday that 51 franchise locations in 24 states were slammed with a malware attack, likely between Jan. 20 and Aug. 11 of this year. That's about 1 percent of its 4,470 U.S. stores. The computing systems of other United Parcel Service (UPS) business entity systems were not affected.

The UPS Store is the latest victim in a string of sophisticated payment system hacks targeting major retail chains. Others similarly hacked include Target, Neiman Marcus, Michaels, Goodwill, and, most recently, Albertson's and SuperValu.

Most impacted UPS Store locations were exposed to the malicious software after March 26. If you used your debit or credit card at any of the breached stores when their systems were compromised, UPS says your information "may have been exposed." However, company spokesperson Chelsea Lee said in astatementthat UPS isn't yet aware of any reports of fraud as a result of the intrusion, which current anti-virus software can't sniff out.

"Please know we take our responsibility to protect customer information seriously and have committed extensive resources to addressing this incident," Tim Davis, president of The UPS Store, said in a lenghty letter to customers. "We understand this type of incident can be disruptive and apologize for any anxiety this may have caused."

An IT security firm UPS contracted with -- after receiving a July 31 warning about the malware from the Department of Homeland Security (DHS) -- uncovered the computer virus during a sweep of the company's systems.

UPS says it's continuing to investigate. Meanwhile, it isn't contacting potentially affected customers directly, but has created awebsiteto address customer concerns.

The company is also encouraging anyone who shopped at affected UPS Stores during the breach to be on the lookout for suspicious debit and credit card account activity. It will also furnishcomplimentary credit monitoring services and identity fraud protectionto customers whose information might have been jeopardized.
