Summary Defining Characteristics

Multiple payment authorisation attempts used to verify the validity of bulk stolen payment card data

Indicative Diagram


Lists of full credit and/or debit card data are tested against a merchant’s payment processes to identify valid card details. The quality of stolen data is often unknown, and Carding is used to identify good data of higher value. Payment cardholder data may have been stolen from another application, stolen from a different payment channel, or acquired from a criminal marketplace.

When partial cardholder data is available, and the expiry date and/or security code are not known, the process is instead known as OAT-010 Card Cracking. The use of stolen cards to obtain cash or goods is OAT-012 Cashing Out.
