Target today confirmed that 40 million customers might be at risk of credit and debit card fraud, due to cyber criminals reportedly gaining access to the Target system. Customers that made purchases from Nov. 27 to Dec. 15 with a debit or credit card are at risk, with stolen data including customer names, credit and debit card numbers, three-digit security codes, and card expiration dates.
With a data breach nationwide, it seems unlikely that a credit card skimmer device was used - and seems more likely that criminals accessed the company's servers - or installed malware on point-of-sale machines. The company is now working with a third-party forensics team to identify how the breach occurred, and to ensure it doesn't happen again in the future.
Customers should contact their banks and the Federal Trade Commission (FTC) if any fraudulent activity is detected. The U.S. Secret Service and Federal Bureau of Investigation (FBI) are currently helping with the ongoing investigation. Online Target shoppers do not need to worry about the data breach.
