Some common scams that fraudsters run to obtain credit card numbers include phishing, vishing, smishing, and online ad scams. Phishing is the most common scam and involves using malicious emails or websites to capture user credentials. Vishing (or VoIP phishing) involves fraudsters using spoofed calls or messages to get victims to share their personal information. Smishing is a variant of phishing that makes use of text messages. Online ad scams involve fraudsters placing deceptive advertisements for legitimate services in order to gather credentials. All of these scams are often quite effective, as a large number of people don't know the best security practices to defend against these attacks.
