4 Years After Target, the Little Guy is the Target
Summary: Four years after the Target breach exposed 40 million cards, Krebs on Security reports that thieves have shifted to smaller merchants, with a new Joker's Stash batch called "Dynamittte" advertising 7 million cards as "100 percent" valid. Test cards from the batch traced back to customers who had recently eaten at Jason's Deli, a 266-location chain in 28 states, and threat intelligence firm Mindwise found a nearly 100 percent overlap between the batch's ZIP codes and Jason's Deli store locations, concluding at least 170,000 cards map back to the chain.
Bottom line: Those 170,000 cards were issued by more than 250 banks and credit unions, each with its own fraud strategy, and by mixing cards from multiple breaches into one batch the fraudsters make it less likely any single chain breach is detected and remediated quickly.
