Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what recent estimate he has made of the proportion of cyber attacks affecting the UK which are state sponsored or coordinated.

In the two years since National Cyber Security Centre (NSCS) was established in October 2016, it has dealt with over 1,100 cyber security incidents. The majority were perpetrated from within nation states in some way hostile to the UK, undertaken by groups of computer hackers directed, sponsored or tolerated by the governments of those countries. For operational reasons, we are unable to provide further detail.
