An Ontario woman is out $86,000 after receiving a call from a fraudster claiming to be a Canada Revenue Agency (CRA) investigator. They told her that her bank accounts were involved in a money laundering operation.
Everything I've read makes me think that a scam is obvious only to those not taken in and those who get the benefit of reading a news story.
This particular scam is a relatively minor variation on the "bank examiner" scam that has been successfully operating pretty much since the invention of banking. With the right play, even people familiar with the scam can be taken in.
She made multiple trips to a Bitcoin machine, Bitcoin alone should be obvious to most people. Mean it sucks for them and I feel for their situation but what government employee is going to tell them to go to a Bitcoin machine?
At the very least set up a new account at a different bank with extra safeguards until it's sorted out.
