Discount retailer Kmart announced that their payment systems were infected by a new form of malware, putting consumers’ credit and debit card information at risk. This latest cyberattack began in early September and was detected on October 9. At this time it is unclear how many stores were affected.
In a statement, Kmart said that at this point in their investigation there is no indication that customers’ personal information, including debit card PIN numbers, email addresses and social security numbers, were compromised.
When the malware was detected it was removed from the retailers’ payment systems. An independent IT security firm has been hired to help with the investigation.
Kmart advised people who shopped at Kmart from September 1 until October 9 to monitor their credit card and bank statements. If they do see any fraudulent activity, they suggest contacting their issuer immediately.
Kmart is offering free credit monitoring services to individuals who used their credit and debit cards at the retail chain when the breach occurred.
Dairy Queen takes a hit too
The Kmart breach came on the heels of an announcement by Dairy Queen that 395 of their DQ locations and one Orange Julius store in the U.S were attacked by Backoff malware. Customers’ credit and debit card information was compromised during the attack, which has now been contained.
Dairy Queen is working with the affected franchises, law enforcement authorities, and card issuers to determine the full extent of the breach. The affected systems did contain customers’ card number, names, numbers and expiration dates, but they do not believe that customers personal information, including Social Security numbers, PINs or email addresses, were accessed by hackers.
There is no set time period for when the breach occurred because each store was independently hacked. A list of the stores and the dates they were affected can be accessed on the website. Both Kmart and DQ are offering free credit monitoring services to customers who used their cards at affected locations.
