About this episode
The episode discusses the AI Cyber Challenge and its impact on cyber defense through the use of AI in securing critical infrastructure.
The AI Cyber Challenge, AIxCC, marks a pivotal inflection point for cyber defense. Numerous attacks in recent years have illuminated the ability for malicious cyber actors to exploit vulnerable software that runs everything from financial systems and public utilities to the health care ecosystem. AIxCC Competitors successfully demonstrated the ability of novel autonomous systems using AI to secure the open-source software that underlies critical infrastructure, with winners revealed at DEF CON 33. Hear from DARPA and ARPA-H on the game-changing results the competitors achieved. And although the competition is over, the challenge continues. All seven finalist teams’ CRSs have been made available as open-source software under a license approved by the Open Source Initiative. Hear from teams on their experiences through the competition and how they are moving their systems to the real world.
