The Russian invasion of Ukraine has been accompanied by a rash of cyberattacks from all sides, as hackers with a wide range of allegiances take up digital arms.
Hours before the invasion began, there was a “new round of offensive and destructive cyberattacks directed against Ukraine’s digital infrastructure,” Microsoft Corp. said in a Feb. 28 blog post. Earlier in the month, Ukrainian banks and defense websites had been taken offline in attacks the U.S. government has attributed to the Russian state. Hackers linked to Belarus, a Russian ally, have also carried out cyberattacks on the Ukrainian military, according to the cybersecurity firm Mandiant Inc.
