The scammer used scare tactics to keep the victim on the line. He even connected her with another scammer who claimed to be working for the police. The two scammers told the victim that her IP address was being used in several countries, and they showed her a picture of a Russian man who they claimed was using her account.
“Throughout this process, they kept telling me not to talk to anybody, not to inform anybody, and to keep the landline on and my hand phone switched off,” the woman told the Times. “Not knowing anything, I just followed through. That's when it all happened.”
This seems a lot of effort on the criminals’ part, but $300,000 is, sadly, a very good return on the two hours they invested. Scammers frequently try to keep their victims isolated and frightened so no one else can warn them that they’re being scammed.
The very same tactics—slightly modified—are being used in office environments. Combinations of pressure tactics, deception, isolation and tag-teaming are used in CEO Fraud as well.
