Sometime around Black Friday a breach occurred at Target stores nationwide, potentially affecting 40 million customers, possible extending through December 15. Only in-store transactions are affected, and the U.S. Secret Service is investigating. It affects all major card brands, but most of them shield cardholders from unauthorized purchases with a zero-liability protection policy.
A breach of credit and debit card data at discount retailer Target may have affected as many as 40 million shoppers who went to the store in the three weeks after Thanksgiving.
Target said customers should now stay on the lookout for fraud and identity theft and contact their banks and the Federal Trade Commission if they notice anything suspicious. Shoppers were cautioned to regularly check their account statements and free credit reports; the chain even suggested setting up fraud alerts.
