Well, I've saw uglier
Some years back, I was the information security officer for a forward deployed military installation. The installation originally being a pre-positioned stock storage facility, which was ginned into depot service for a certain pair of wars.
While there, our enterprising folks with the Patriot missile battery decided to connect their missile battery command post to the installation network. Not a whisper of a by your leave, just jackass in and hope for the best.
So, I'm walking from the chapel parking lot, where I stowed my vehicle upon arrival to work and came upon a cat 5 network cable ever so carefully stretched along the ground, with concertina wire protecting it. Yeah, razor wire security and worse, when I followed said offending, unauthorized cable, it was plugged into our classified network.
I disconnected the cable, changed the combination on the door lock and cut several 1 meter segments from the cable, then kicked the rest of the cable into the wire, then filed a thoroughly irate report as to the major security breach. Their harebrained attempt ended immediately.
Around two weeks later, they dutifully launched one of their Patriot missiles in the general direction of the airport, thankfully, not locked onto any target. The missile, lacking a target, promptly committed suicide and crashed into the ground - literally in the Minister of Defense's actual back yard.
Said unit then became the patriotless missile battery for the duration of their stay in country.
Alas, both stories are entirely true and involved one singular unit.
