The UK and allies from 10 countries have exposed what they say is a campaign of malicious cyber activity by Russia against logistics and tech firms involved in delivering foreign assistance to Ukraine.
The National Cyber Security Centre (NCSC), which is part of GCHQ, said a unit within the Russian intelligence service, GRU, had targeted defence organisations, as well as IT services, maritime, airports, ports and air traffic management systems firms in a range of Nato countries.
