They later followed up with another tweet which showed the Switch running on Linux with a GUI on top of it, and it appears that the interface can be interacted with using the Switch’s touchscreen display. Ultimately what this has resulted in is a Linux-based tablet. The group has not disclosed how they went about the hack, despite many asking for instructions or some information. The group even claims that their Switch coldboot exploit cannot be patched.

It is unclear what the group plans to do with their hack, and whether or not it was done just to prove a point or if there are bigger plans. That being said, admittedly there haven’t been that many successful attempts we’ve seen so far, which means that in terms of piracy Nintendo doesn’t really have to worry too much for now.
Presumably Nintendo might have learnt from some of their previous consoles, such as the Wii which was successfully hacked to allow the downloading and running of pirated software.
