‘The world should be prepared’ — Microsoft issues warning about Russian cyberattacks over winter

The Prestige ransomware attacks were the first cyber operations to affect entities outside of Ukraine since the Viasat hack at the start of the invasion in February, Microsoft said. The company said Russia’s military cyber operations have now expanded beyond Ukraine to hit Poland, referencing the ‘Prestige’ ransomware attacks which recently targeted the country’s transport and logistics sector. Microsoft last month attributed these attacks to the Iridium hacking group associated with the GRU, Russia’s military intelligence agency.
