Russian Aggression Toward Ukraine: Cyber Threats

February 18, 2022  • Aspen Digital

Three decades after the fall of the Soviet Union, Russian troops stand at the border of Ukraine in a pivotal moment for the young democracy. Meanwhile, governments, industry, and the public brace for potential escalation at the border—and the keyboard. In this session, leading intelligence and security experts will discuss how a cyber conflict might unfold and what it might mean for Ukraine—and the world.

We are joined by:

  • Sandra Joyce, EVP and Head of Global Intelligence, Mandiant
  • Herb Lin, Senior Research Scholar, Center for International Security and Cooperation; Hank J. Holland Fellow in Cyber Policy and Security, Hoover Institution
