Britain under cyberattack daily

Britain is under constant cyberattack mostly coming from China and Russia it has been reported. GCHQ's Office of Cyber Security works around the clock to defend government computer systems and vital parts of the national infrastructure. Over 300 attacks have been recorded on public sector systems over the last year. MI5 believes the attacks are state-sponsored and as well as gathering information they could also be attempts to infect key infrastructure like the national grid with computer viruses to shut them down.
