Ukraine has seen a threefold increase in cyber-attacks over the past year, with many of them originating from Russia. These attacks have sometimes been used in combination with missile strikes, according to Viktor Zhora, a leading figure in the country's SSSCIP agency. The attacks have often taken the form of destructive wiper malware and have been aimed at Ukraine's critical infrastructure. During a recent visit to the UK's National Cyber Security Centre, Zhora and Ukrainian colleagues discussed how to work together to tackle the Russian threat. A recent analysis by SSSCIP linked cyber-attacks on Ukraine's energy infrastructure last autumn to Russia's sustained bombing campaign, with the aim of causing maximum disruption to everyday life.
