Last year Russia infiltrated the digital networks of federal agencies and many of America’s largest corporations, and last week’s armed insurrection on the US Capitol was fomented through disinformation campaigns on social media. Cyberattacks and manipulation of elections and domestic affairs threaten national security and global relations. John Carlin of the Aspen Institute’s Cybersecurity & Technology Program leads a conversation with Kevin Mandia, CEO of FireEye, the cybersecurity company that uncovered last year’s massive Russian hack, Senator Mark Warner, Vice Chair of the Senate Intelligence Committee, and Luta Security’s  founder and digital defense expert Katie Moussouris. They discuss how the Russian hack was discovered and what it means for the future of digital security worldwide, including how to assign responsibility for cybersecurity and social media failures. Senator Warner also shares his assessment of the damage of a foreign-led cyber attack compared to the domestic insurrection he experienced at the Capitol. Their conversation was recorded on January 7, 2021.
