Look at pages 10-17 to see how the law is evolving here.
From that lens, that feels like users could be held liable for what these hacking agents are doing. Which in some cases probably makes sense, but certainly not all.
I've seen plenty of cases of Claude having an action blocked so trying tons of workarounds to accomplish its goal, I could easily see it doing this on something more broad.
The service that this whole thread is about is explicitly a "hacking agent", designed explicitly to try to hack things, and was then pointed at a third-party (seemingly without their permission).
Anthropic/OpenAI can reasonably claim that they had no intent and are trying to stop it. OP here did this explicitly and purposely.
In terms of "We wrote a hacking agent designed only for hacking and sell it as a self-hacking service and then pointing it at someone else and omg can you believe what it did we had no intention of hacking" sense, I don't think that's really applicable.
The mens rea is explicitly there and it's not valid for them to try to hide behind an "agent".
Ya, returned it after poking through all of the drawers and iterating through business information that they found.
There is a white-hat line that OP very clearly crossed here.
