Chairman Burr, Vice Chairman Warner, and members of the Committee, thank you for inviting me to speak today about the security of U.S. elections. I’m here to tell you not just what I think, but about concerns shared by hundreds of experts from across cybersecurity research and industry. Such expertise is relevant because elections—the bedrock of our democracy—are now on the front lines of cybersecurity, and they face increasingly serious threats. Our interest in this matter is decidedly non-partisan; our focus is on the integrity of the democratic process, and the ability of the voting system to record, tabulate, and report the results of elections accurately.
My research in computer science and cybersecurity tackles a broad range of security challenges.1 I study attacks and defenses for the Internet protocols we all rely on every day to keep our personal and financial information safe. I also study the capabilities and limitations of the world’s most powerful attackers, including sophisticated criminal gangs and hostile nation states. A large part of my work over the last ten years has been studying the computer technology that our election system relies on.2 In this work, I often lead the “red team,” playing the role of a potential attacker to find where systems and practices are vulnerable and learn how to make them stronger.
I know firsthand how easy it can be to manipulate computerized voting machines. As part of security testing, I’ve performed attacks on widely used voting machines, and I’ve had students successfully attack machines under my supervision.
