China accused of cyber-attacks on Ukraine before the Russian invasion

China launched cyber-attacks on Ukrainian military and nuclear targets shortly before the Russian invasion, according to a report.

The UK government confirmed that the National Cyber Security Centre was investigating the allegations, which claim that more than 600 websites, including Ukraine’s defense ministry, were subjected to thousands of hacking attempts coordinated by the Chinese government. A UK government spokesperson said: “The National Cyber Security Centre is investigating these allegations with our international partners.”

The claims are based on intelligence memos obtained by the Times. However, the Ukrainian security service denied on Friday night that it had supplied any information on the alleged attacks.
