Security expert Bruce Schneier has warned that talk of cyber terrorism could have a damaging effect on levels of IT security.
He is concerned that resources are being diverted away from the fight against cyber crime as governments focus on cyber terrorism.
He said: "We should not ignore criminals and I think we're under-spending on crime. If you look at ID theft and extortion - it still goes on. Criminals are after money."
He said: "There is definitely a marketplace for vulnerabilities, exploits and old computers. It's a bad development but there are definitely conduits between hackers and criminals."
