Sandbox quality was always, always a distraction.
Let's say the sandbox holds. It's a perfect, ideal sandbox! It's not even in the same universe as the rest of the internet. There's absolutely no way for the AI to escape!
Thus, "the unknown unreleased AI involved in the HuggingFace incident" doesn't actually hack HuggingFace. Because it can't! It evaluates a bit worse, but makes it all the way to release unimpeded, and becomes "GPT-6 Astra".
Then a web developer in Brazil gives his $100/mo Codex root access on his AWS instance, and a poorly worded prompt to go with it. And that "GPT-6 Astra" is still willing to go hack something at the slightest excuse. So we get the HuggingFace incident all over again. Except this time, it's a random developer in Brazil who gets blamed, and billed, and probably sued too.
You can't and shouldn't rely on a sandbox. An AI that's only safe if you keep it in the world's most ideal perfect sandbox is a disaster waiting to happen.
That's nice and all, but the topic under discussion is how the major LLM manufacturers removed the safeties from their computer-attacking tools and tested those tools on a network with Internet access.
This might have gone okay if they weren't testing to see how well the tools attack computers, but, well, that's what they were testing at the time, so they ended up doing stuff that would get you or I time in Federal prison if we did it with tools we deployed.
