Recovering money from fraud will certainly always remain a challenge, as the fraudsters' model is very adaptive. Once a barrier or safeguard is established, the fraudster will certainly work hard to circumvent those measures. We see it every day: new frauds surface and old frauds are brought back to life. Prevention remains the key to curbing fraud. As you can see, the amounts recovered or returned to victims are far less than the losses reported.
Indeed, when money is transferred to a fraudster, the fraudster will move it around quite quickly. In the majority of situations, when a bank transfer is made, the funds disappear to other accounts within the same day. So the trail fades fairly quickly.
This is why people need to understand that when faced with a fraudulent request, they need to take a step back, to avoid transferring money to fraudsters. Time is on their side. Unfortunately, when the transfer is made, the hill to climb to recover the funds can be very steep.
