DIY Spy drone cracks Wi-Fi networks and cell data

[n2ize]

"But it still doesn't seem to make much sense to use a drone for doing things like cell phone and wifi interception that can just as easily be done from the ground. I have a couple of reasons for feeling like this."

It would make sense in a war zone, where you cannot be on the ground. I guess maybe in a neighborhood where you don't fit in.

Right, maybe. But I am talkig about non-military apps.

[QUOTE] "1) It is illegal and dangerous to fly drones over populated areas. Unless your target is in a sparsely populated area and close to a field where you can launch your drone and monitor its flight from the ground it won't be of much use and can land you in a heap of trouble. A relatively small rc plane or helicopter capable of carrying enough equipment can easily kill or maim a person if it were to go out of control."

Smaller systems can be hand launched and parachute or wire recovered from the top of any building. We demonstrated this to the NYPD. With a video camera to do first person flight, we could direct an R/C aircraft with a 1 lb block of "Clay" into a two foot by two foot window.

With my smaller helicopters I can fit in through a smaller window. Nothing special here. Also, if there is any appreciable wind all bets are off.

Small electric or gas engine powered air vehicles hardly ever get noticed compared to stationary balloons.

probably not, but they are still quite noticeable once they start operating at low altitudes in close proximity to people. Electrics are quiet but as they get closer they are easily heard and draw attention.

Also, How small is small ? A 350 sized electric helicopter can inflict some nasty injury if it smacks someone head on. A 450-500 can kill a person. Quadcopters are somewhat safer. But any rc aircraft that can lift a few pounds of equipment can only be so small and only be so safe in a crowded area.

"2) If you cannot control it via line of site then you need either FPV or radar guidance to fly it beyond your line of site. This starts to become quite expensive and again, quite illegal, esp over populated areas. There are permits that can be acquired but they are rather hard to get."

The one in he story is GPS guided. You preload the surveillance flight path and altitude into the flight computer, then send it on its way.

yeah, thats all well and good. But still, dangerous in a populated area. Esp without someone in control to compensate for the unexpected. Also illegal unless you are fortunate enough to have the proper permits which are not just issued to anyone.

"3) Both electric and gas powered flight is high in energy consumption. Thus air time is short unless the drone is very well designed from the ground up for long sustained flights."

A 20 mile race track is possible. Opportunities to collect lots of Wifi locations and passwords.

If you need to get into the air to collect vast numbers of wifi locations and passwords you are either doing something illegal or, are a part of some spy program that is probably funded well enough to have access to full sized aircraft and/or a large budget for remote controlled gadgets. And even in the former case, most urban area are chock full of wifi signals and you can collect thousands of locations from the ground. But in most cases the cops know who they are targeting and can monitor that persons wifi or cell phone from the ground. No need to intercept everyones signals throughout an entire city. Furthermore it's easily thhwarted by not using wifi or a cell or cordless phone. Anyone who is doing something illegal and puts it out over a wifi or a cell phone is an idiot and deserves to get caught for being stupid.

"4) Night time or bad weather ... well need I say more ?"

Night time is no issue for a GPS guided drone, bad weather, well even the USAF stays home.

True but then again, the need to send a drone up at night to spoof cellphones and collect wifi data for a any legitimate purpose is rare. Generally if law enforcement is targeting a particular individual or location they can intercept signals from the ground. No need to collect thousands of wifi signals.

The amazing part of that aircraft is the Computer with a 340 million word vocabulary. It breaks the password protected Wifi sites!

Not too amazing. it sounds like nothing more than a brute force plain-text dictionary attack. easily thwarted by using random passwords of adequate length and/or a strong encryption method.
