> Do you supply it power? Then you it could induce feedback over the cable which triggers new programming in nearby electronics.
We could feed it through power a little solar panel. Or just give it batteries and accept that it will run out of power eventually. There are plenty of ways to power a computer without allowing it to connect back.
> Does it have any means of creating sparks/heat would could be used to make a hole in the faraday cage?
Assuming it has no access to electronics other than the ones that it needs to function, I don't see how it could overheat one of those parts to over 1811 Kelvin (the melting point of iron) to destroy its Faraday cage without destroying itself. Or we could just cut the power when it tries to mess with the cage, or does anything else that we don't understand.
> What about neutrinos or gravity waves? How would you stop those?
Why would we? We need very expensive detectors to even measure those. How much damage could it do using neutrinos and gravity waves?
> We could feed it through power a little solar panel.
A solar panel seems 1-way, but it isn't totally. Fewer photons would be absorbed if say, higher resistance would be applied. By modulating that resistance, it could sent messages to the outside.

If we understand everything it's doing, it's not more intelligent than us. It must be incredibly stupid because we can't even understand a worm.

Because otherwise it can establish 2-way communication with the outside world and possible nefarious actors.
