Policing cybercrime internationally or domestically is a difficult proposition at this stage of technological advancement and investigative agencies are working every second to prevent the damage done by cyber criminals. The rapidly spreading of illegal computer activities and the criminal exploitation of vulnerabilities has police worldwide in their heels. National governments and their police agencies have invested huge efforts and resources to combat cyber-crimes. “The cross‐national nature of most computer‐related crimes has rendered many time-honored methods of policing internationally, domestically and in cross‐border situations ineffective even in advanced nations, while the “digital divide” provides “safe havens” for cyber‐criminals” (Broadhurst, 2006). This paper will focus on three main and most common scams and cybercrimes that the FBI encounters: The so- called “Nigeria 419” Fraud Scheme, Advance fees Scheme and common elder fraud schemes. The paper will review what they are, how they are carried-out and best practices to prevent, control and apprehend these cyber criminals.
