Al Qaida is intent on using the internet to launch a cyber-warfare campaign against the UK, ministers have revealed. Terrorist groups, which already use the internet for recruitment, propaganda and communication purposes, want to turn it into a dangerous weapon.
Security Minister Lord West issued the warning as he published the Government's new Cyber Security Strategy aimed at heading off online threats. As well as potential cyber-attacks from terrorists, the UK faces a real and growing threat from foreign governments such as China and Russia, and from organised criminal gangs, he said. Targets include key businesses, the national power grid, financial markets and Whitehall departments. As part of attempts to beef up defences, a new Office for Cyber Security will be set up to co-ordinate Government policy.
