So what if you can hack into time squire’s big bulletin board and put your real estate ad up for hundreds of people to view? I bet you can get a lot of leads.

This video shows how easy it can be done. There is no black van parking at the corner of the street full of electrical equipments, just one guy with an iPhone.

Is it illegal? I bet it is. But it’s still fun to see that how easy it can be done. Digital bulletin board will get more popular for their flexibility to change ads, but it also has its share of vulnerability to be hacked into.

Here is some technical details if you are interested:

“The way it works is pretty simple: plug in my transmitter into the headphone minijack of an iphone 4 and play back any video clip. you can play it through the ipod feature or through the camera roll. the transmitter instantly sends the video signal to the video repeater and the video repeater overrides any video screen that it’s being held next to. it doesn’t matter what shape or size the hacked screen is because the hack video will simply keep its correct dimensions and the rest of the hacked space will stay black.”
