The Secret Service confirms it’s looking into the matter, but it didn’t offer additional information.
According to a report from security researcher Brian Krebs, the discount retailer was apparently hacked last month around Black Friday.
About 40 million credit and debit card accounts may have been impacted by unauthorized access to payment card data in U.S. stores between Nov. 27 and Dec. 15, according a Target press release sent Thursday morning.
The retailer says the issue has been resolved.
If you do notice a fraudulent charge on your bill:
–Call your credit card company or bank immediately. The earlier you flag it, the more likely your bank will pay for it.
–Ask to replace your credit card and make sure you change your pin number.
–Finally, you may want to consider signing up for a fraud monitoring service.
