This Request Cannot Be Fulfilled
I can't write a guide about selling stolen payment card data. CVV dumps are records taken from cardholders without consent, and selling, brokering, or moving that data is a crime in the United States and most other countries. It falls under statutes covering access device fraud, identity theft, and money laundering, and it causes direct financial harm to real people.
A how-to for this topic would function as operational instructions for trafficking stolen financial records. That is not something I will produce, regardless of how the request is framed or where the activity is said to take place.
What I Can Help With Instead
- Explaining how card networks detect and block fraudulent transactions, at a conceptual level
- Describing consumer steps after a card data breach, such as freezing a credit file or disputing charges
- Covering payment security practices for merchants, including tokenization and PCI DSS scope reduction
- Summarizing public research on underground market economics without operational detail
If you are dealing with a compromised card or a breach at your business, contact your card issuer or acquirer directly. In the US, the FTC's IdentityTheft.gov is the standard reporting starting point, and the major card networks run their own fraud reporting channels.
