The Financial Intelligence Centre (FIC) released a Typologies document that gives an overview of nine different types of criminal activities and methods used to abuse the financial system. Amongst these are Money Laundering, Corruption, Cybercrime.
This is a worthwhile read as each type of criminal activity is thoroughly explained and accompanied by a real-life scenario in the form of a case study. There are also notes on what you should look out for to identify a possible and prevent a possible criminal act.
