A cyber security expert recommends getting a new credit card number if you believe your financial information was compromised in the Target security breach.
A local cyber security expert who previously worked for the U.S. Secret Service calls the security breach at Target Corp. a "well planned and sophisticated attack" and recommends consumers protect their financial information by getting a new credit or debit card.
Target confirmed Thursday on its website a security breach that potentially exposed the credit and debit card information of 40 million customers who made purchases at its store between November 27 and December 15.
The Secret Service is investigating the security breach. It's recommended consumers watch their accounts for any suspicious or unusual activity.
"They need to be diligent and continue monitoring their credit card statements," said Mark Lanterman, CEO of Computer Forensic Services in Minnetonka.
Lanterman, who previously worked as a member of the U.S. Secret Service Electronic Crimes Task Force, said data thieves will often hang on to the financial information for months or even a year before using it, so consumers should continuously monitor their accounts for any fraudulent activity.
If you know you used a credit or debit card at a Target store between November 27 and December 15, Lanterman recommends contacting your financial institution to request a new card with a new number.
"Take responsibility for your own security and be proactive," said Lanterman.
