The scam works like this:
You receive a call from someone who says they are from the taxation office or internal revenue service in the country where you are studying.
The caller says that there is a serious problem relating to the payment of tax, for example:
The caller threatens you with very serious consequences unless you immediately pay a ‘fine’.
The caller usually requests that the fine is paid by wire transfer, bitcoin, or gift cards.
If you pay the fake ‘fine’ your money is gone.
