It’s not just online transaction databases that are susceptible to attacks. The retailer Target is reportedly looking into the theft of millions of in-store credit card and debit card records from its databases. Customers all over the United States were victimized, reported Brian Krebs, who cited people at two of the top 10 credit card issuers in the US. Both of them said that the breach started on or around Nov. 29, the busy shopping day known as Black Friday, and extended to at least Dec. 6, and possibly as long as Dec. 15. “The breach window is definitely expanding,” an anti-fraud analyst in the US told Krebs. A data breach investigation firm representative who wished to remain anonymous said that they expect this breach to compare in scope to “some of the largest retail breaches to date.”
