Why it’s a bad idea to have your device’s IP address publicly visible!

You know how you walk into an office building, and the machines standing around have stickers on them with their IP address clearly visible to the general public?

Well, thank you for that! You just saved me a ton of work figuring out which printer I want to attack to get access to the rest of your system.

And while this may sound sarcastic or ironical, if I’m in your network I’ve managed half the task!

Giving me a publicly visible IP address is technically like giving me the key to your doors.

Yes, I could smash the windows to get in but the effort of just unlocking the door with the key is significantly easier, and saves me some time.

So if we could just agree upon having the stickers on the back of the printers, where not every customer, and every employee, and every hacker who just social engineered their way into your building, we would be in a better world by tomorrow.
