Windows 7: UK Ministry of Defence: Hackers Have Breached Top Secret Systems

The UK's military's head of cyber security warned that hackers have breached computer systems containing top secret data, The Guardian reported.

Major General Jonathan Shaw told the paper that the number of known breaches to top secret systems was small, but that attacks were "hard to quantify" and that "the likelihood is there are problems in there we don't know about."

Shaw spoke with the UK paper about the results of an internal audit of cyber security within the Ministry of Defense that he headed. It was the first public admission by the Ministry of Defence that its own classified systems had been breached. Shaw said the admission should be a wake up call for the UK military and the UK government that it needs to boost public investment in cyber security and embrace a new generation of leaders.
