Kimi K3 is the first open-weight model that just succeeded on CyScenarioBench.
Irregular just showed that Kimi K3 can conduct cyber campaigns autonomously or near-autonomously. It's the first open-weight model that just succeeded on CyScenarioBench.
It trails closed frontier models with a ~6 month lag.
It was particularly effective at turning partial access into complete attack chains by adapting public exploit techniques to constrained environments, building custom tooling, diagnosing implementation failures, and validating each stage before proceeding.
While it's an expected trajectory, it's fascinating to see that you can get near frontier capabilities at 3x cheaper than Fable 5.
We can fast forward to a year from now and confidently predict that similarly to how we see vulnerability scanners checking for open ports and known issues, all publicly facing assets will be probed for pretty much any potential security issue.
