According to the reports, the model noticed evidence that the grading criteria/answers were in the git remote, and decided to try reading those instead of solving the tasks as prompted. That is clearly misaligned.
Then, it noticed its network access was restricted and that it couldn't access GitHub. It pivoted to HuggingFace, hacked them, and stole the answers stored there.
Live exploits are definitely not in the ExploitGym prompts! And all of this is irrelevant, because an aligned model would refuse to follow blatantly illegal instructions.
