What is a CVV and a Dump?
A CVV (Card Verification Value) is a three- or four-digit number on credit and debit cards, used to verify the cardholder during transactions. A dump, on the other hand, refers to a set of information extracted from a compromised credit card.
Significance of CVV and Dumps in Security
- CVV is crucial for preventing unauthorized transactions as it is not typically stored in transaction data.
- Dumps can lead to identity theft if not properly secured, as they contain sensitive financial information.
- Online merchants should implement robust security measures to protect against the misuse of CVV and dump data.
