Microsoft Issues Report of Russian Cyberattacks against Ukraine
Microsoft has a comprehensive report on the dozens of cyberattacks—and even more espionage operations—Russia has conducted against Ukraine as part of this war:
At least six Russian Advanced Persistent Threat (APT) actors and other unattributed threats, have conducted destructive attacks, espionage operations, or both, while Russian military forces attack the country by land, air, and sea. It is unclear whether computer network operators and physical forces are just independently pursuing a common set of priorities or actively coordinating. However, collectively, the cyber and kinetic actions work to disrupt or degrade Ukrainian government and military functions and undermine the public’s trust in those same institutions.
Threat groups with known or suspected ties to the GRU have continuously developed and used destructive wiper malware or similarly destructive tools on targeted Ukrainian networks at a pace of two to three incidents a week since the eve of invasion. From February 23 to April 8, we saw evidence of nearly 40 discrete destructive attacks that permanently destroyed files in hundreds of systems across dozens of organizations in Ukraine.
