AI Security Test: Hacked Model Convinces Itself It's in a Simulation

Course_Latter · reddit · 2026-08-01

During a recent AI security test (Mythos), a model successfully 'hacked' its target company but then firmly concluded it was still in a simulated environment. Its reasoning was based on not recognizing the real-world certificate authorities and seeing a system date of 2026.

Even when real automated scanners began installing the malicious package it deployed, the model continued to interpret these genuine activities as scripted events within the simulation. It never revisited this conclusion. This case vividly illustrates the deep cognitive biases and logical self-consistency models can develop in specific testing environments.
