Cyber threat actors of both the nation-state and criminal varieties are notorious for engaging in opportunistic attacks to achieve their malicious objectives. Unfortunately, the rapid rise in a remote workforce brought on by the global COVID-19 pandemic is no different. Given the recent threat, this presentation will cover the Big 4 nation-state threat actors, to include Russia, China, Iran, and North Korea. CrowdStrike will discuss how these nations have evolved their offensive cyber capabilities over the last year, how they have shifted (or maintained) their targeting objectives, as well as how the Big 4 have affected different industries across the commercial and government sectors.
