Understanding CVV Attacks
CVV (Card Verification Value) attacks are a type of fraud where cybercriminals steal credit card information, including the CVV number, to make unauthorized purchases online.
How CVV Attacks Are Carried Out
- Cybercriminals use phishing techniques to steal your credit card information.
- They also employ malware that can capture your card details when you make a purchase online.
- Stolen credit card numbers can be used to make fake cards, leading to more sophisticated CVV attacks.
