DARPA announced the AI Cyber Challenge (AIxCC) winners at DEF CON 33, ending a two-year effort to test whether AI can secure open source technology underpinning critical infrastructure. The program matters because it produced working cyber reasoning systems (CRSes) that can find vulnerabilities and generate patches at scale. DARPA also said all seven finalist CRSes will be made available for open source use.

President Donald Trump signed a June 2 executive order that sets up a voluntary framework for developers of covered frontier models to give the US government access for cybersecurity review for up to 30 days before release, while expressly rejecting any mandatory licensing or preclearance requirement. The order directs NSA, CISA, and NIST to build a classified benchmark for determining which models cross the covered threshold and creates an AI cybersecurity clearinghouse led by the Treasury Department. The framework closely echoes Anthropic's Project Glasswing, which gives vetted partners early access to Claude Mythos Preview to scan critical software for vulnerabilities.

Wiz's research arm launched Zeroday Cloud, a bug-bounty competition for open-source cloud and AI tools with a $4.5 million prize pool, backed by Google Cloud, AWS, and Microsoft and scheduled for December 10 and 11 at Black Hat Europe in London, UK. The contest spans six categories across AI, Kubernetes and cloud-native, containers and virtualization, web servers, databases, and DevOps & automation, with payouts ranging from $10,000 to $300,000. Submitted exploits must achieve complete compromise, defined as a full Container/VM Escape for virtualization targets or a 0-click Remote Code Execution vulnerability for other targets, and participants must register through HackerOne, complete ID verification and tax forms by November 20, and comply with one-entry-per-target and country-restriction rules.

    DARPA announces AIxCC winners and open-source release plans

    Initial Disclosure

    DARPA announced the AI Cyber Challenge (AIxCC) winners at DEF CON 33 in Las Vegas after a two-year effort to test whether cyber reasoning systems (CRSes) could secure open source software underlying critical infrastructure. The finalists analyzed 54 million lines of code, found 54 synthetic vulnerabilities and patched 43, and also uncovered 18 real vulnerabilities that were disclosed to open source project maintainers; teams submitted 11 patches for real bugs. Team Atlanta, Trail of Bits, and Theori won the competition and were awarded $4 million, $3 million, and $1.5 million, and DARPA said all seven finalist CRSes will be made available for open source use.
