Experts: Target Hackers Will Be Tough to Find - ABC News: "The underground markets always have a steady supply of card numbers on sale and their locations are always moving as they try to elude law enforcement, says Daniel Ingevaldson, chief technology officer at Easy Solutions Inc., a firm that sells anti-fraud products and tracks the activity of the online black markets. A big jump in inventory usually indicates there's been a breach of a major retailer. That's what Ingevaldson's firm saw in the cases of both Target and Neiman Marcus, which also recently reported a breach. While many of these online bazaars and forums are based in Russia and Eastern Europe, much of the chatter is in English and appears to have been written by Americans, Ingevaldson says. The types of criminals who buy the card numbers run the gamut, ranging from purely online white-collar crooks to street gangs.
"In reality, card numbers can be bought by anybody with access to the forums and a few Bitcoins in their pocket," Ingevaldson says."
