At the Cyber UK event in Belfast in April, UK Minister Oliver Dowden warned of Russian-associated hacker attempts to disrupt or destroy critical UK infrastructure, while the National Cyber Security Centre issued an official threat notice.

Threats to critical national infrastructure (CNI) however are not new. We have already seen how the war in Ukraine has shaped the cyber security picture in Europe and driven a number of attacks against key infrastructure targets. For example, the attack against Viasat just an hour before Russian troops invaded Ukraine resulted in an immediate and significant loss of communication. It also had the secondary result of paralysing 9000 German wind turbines that rely on satellite communication for their operations.
