Cybercriminals have multiple markets to get illicit goods and prices on these underground forums are likely driven by supply and demand, just like in the legal economy. Full packages of data that can be used to steal a US victim’s identity sell for $4-$10, the researchers say. The price seems low but it can get as high as $65 when accompanied by financial information, such as credit scores. The better the credit score, the higher the price, so fraudsters are more likely to succeed in their endeavors.
