We don't have any special units in Interpol for doing those kinds of things, but I can give you one example of how spam emails were involved in cybercrime. We did an operation in the ASEAN region early this year, and with the assistance of some private companies we were able to identify about 8,000 malicious servers.
Just to give you an idea, among those 8,000 servers, over 7,000 were sending spam emails. The remaining 1,000 were involved in ransomware, banking scams, and other things. It is very common in the cybercrime field for criminals to use compromised computers and servers to send out spam emails.
