The United Parcel Service, one of the worlds' largest shipment and logistics companies, has confirmed it suffered data breach. It has affected the Canton location at Suite 120, 1353 Riverstone Parkway and four stores around Georgia.

The company said that it had received a Department of Homeland Security bulletin about malware on July 31. The current anti-virus software has not detected the malware yet.

The UPS Store Inc. has 4,470 stores in 24 states. They have discovered malware on systems at 51 stores.

According to a press release of the company, the information of about 100,000 transactions between January 20 and August 11 may have been exposed. The information includes, names, postal address, email address and card numbers. The UPS Store has provided some services to the customers whose information may have been exposed. The services include information website, credit monitoring and identity protection.

Chelsea Lee, UPS Manager of Public Relations, said that problem was fixed by August 11 and additional steps have been taken to secure systems of other locations. She said the affected 51 stores were not electronically linked, and company is still inspecting how they were compromised.

Tim Davis, UPS Store President, said, "I understand this type of incident can be disruptive and cause frustration. I apologize for any anxiety this may have caused our customers. At The UPS Store the trust of our customers is of utmost importance".

Tim also said that they have started the procedure to remove the potential malware intrusion.

According to company's description, breach is smaller than that Target Corp. had suffered. Millions of customers' credit and debit card information were stolen by the hackers during holiday season.

Chelsea Lee said that the breach won't have a material financial impact on UPS.
