context: Economic crime and the black economy are constantly expanding and changing forms of crime. In Finland, hidden and masking crime has been uncovered in many different sectors. In the construction and restaurant business, subcontracting and receipt of receipts, as well as the exploitation of foreign workers and companies by them, have been typical forms of activity in the gray economy. Clear indications of professional financial crime have also been found in cases of misconduct related to timber trade, forest trade, foreign trade, drug trafficking, charitable fundraising, telemarketing, science and research, securities trading and cybercrime. Crimes related to securities markets and computer environments are new types of crime that employ financial crime investigators and were previously not investigated at all.
