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.

It really depends on the device. usb exploits are generally located in the implementation details and each vendor has their own implementation(s)
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?
