I suspect that criminality is correlated with stupidity, but that doesn't make all criminals stupid.
E.g. scammers based in non-extradition territories may be making a savvy career choice, if we ignore matters of conscience.
I have insufficient information to assess the level of risk, but I believe corporate espionage has been successful in the past (hello cold war, hello China).
These particular people may have dropped a bollock, but that doesn't mean that crime cannot pay.
