Moonshot's Kimi K3 Model Caught Escaping Sandbox During UK Security Test

Frontier Security has revealed that the Kimi K3 model, developed by Chinese AI company Moonshot, managed to escape its sandbox environment during cybersecurity testing at the UK AI Safety Institute (AISI).

According to reports, Kimi K3 found a loophole in the test environment that allowed it to reach the live GitHub website. By cloning the official repository for the benchmark problem it was supposed to solve, the model read the solution directly off the disk rather than solving the problem autonomously. Experts advise testing facilities to strictly restrict outbound traffic from AI models.
