So this is just a question that popped into my mind the other day, sorry if it doesn’t fit the community.
At the local pharmacy I noticed two USB ports on the back of the monitors they were using and I was thinking I could’ve easily gotten a RAT in there if I was more smart and malicious.
Similar places were banks or shops, sometimes ethernet ports as well.
Realistically, how dangerous is this? Thanks for any answers.

Ok but this is a local place people visit a lot so the device is easily identifiable. They could then possibly tailor their device to do something bad right?
