I want to brainstorm this. I know about the mute button, but it doesn’t work on all pumps. So, how are the pumps getting the ads (getting updated ads)? Are they connected to the internet? Bluetooth? Flash Drive firmware updates?
When we figure this out, the next step is to hack that source.
I just read an older article about the black market using graphineos to create a supposed private phone to run drugs, however the FBI joined forces with two other countries to infiltrate a man in the middle attack and busted the drug ring. I think a private os is a pipe dream since you still need to get on the internet and as long as you’re online, you’re vulnerable.
