Keep a close eye on your account activity and report suspicious transactions immediately to your bank or credit card provider. If your information was part of a breach, the most immediate risk is that the thieves may make unauthorized charges or debits to your accounts. This theft of credit and debit card information could impact tens of millions of consumers and we want to let you know what you can do to protect yourself if you spot fraudulent charges. Lately, we’ve received a lot of questions about what to do in light of the recent data breach at Target retail stores.
