Cybercrime --- As you have mentioned it's difficult to find a reliable source of information. Answering your question I think we now low to nothing about the real cost of cybercrime since all the cyber criminality is not being monitored, and yes I believe this is just the tip of the iceberg. Being a bit paranoid I believe there are tools (software/hardware) that could be used for cybercrime or against it that haven't been revealed to the end users and obviously they could become a risk.
