All About Fraud: How Crooks Get the CVV

Summary: Krebs on Security explains that online fraudsters obtain CVV2 codes mainly through phishing or Web-based keyloggers installed at online merchants, which capture form data including card verification codes as customers submit it during checkout. The piece notes that stolen card "dumps" from point-of-sale systems sell for about $20 apiece but lack CVVs, while CVV bundles sold in "CVV shops" go for $2-$5 each because they work only for online transactions.

Why it matters: A compromised endpoint on either side of a Web session defeats the encryption protecting it, so a merchant's checkout page can leak full card data including the CVV2 without any breach of stored records. The $2-$5 price of a CVV bundle shows how cheaply card-not-present fraud can be mounted against online stores.
