If you work in online fraud prevention, chances are you've caught the "bug". The bug that makes you passionate about identifying & preventing cybercriminals from getting away with stealing from your company, or your client's companies. Most people who have made cyber-fraud their career have the perfect balance of analytical and social skills, a strong sense of justice and the curiosity that will drive you to go down every path of information until you "crack the case".

Just like sociology is the study of social behavior, and psychology is the study of human behavior, Fraudology is the science and study of fraud.

With guests ranging from former cybercriminals to fraud-fighters at Fortune 500 companies to law enforcement and others, you will no doubt be entertained, while learning a lot about fraud & other forms of abuse prevention!
