The paper is $25 .... mmm http://arc.aiaa.org/doi/abs/10.2514/6.2014-4029
This post has some more info https://plus.google.com/117663015413546257905/posts/WfFtJ8bY...
Even more, mounting "something" to the front window is illegal in a lot of places in the world [1]. At least Netherlands and U.S. In The Netherlands operating a phone while driving (voice operated carkit exempt) gives you a ~$250 fine.
Furthermore, obstructing part of your window is dangerous. You could miss something. And it's distracting (our eyes focus on motion).
What a idiotic idea.
Takes a few hours, I like to burn all my data to Bluray (50GB per disk) while watching a movie.
Store the bluray data sets at a friend's house and never worry again.
I'm a model RC pilot for 20 years and these kind of "stunts" are hurting the hobby. At least ask for permission next time.
A phantom only has 4 motors, and the quality is "meh" - there is hardly any 2nd control (fa I have tripple recievers in my jets, if one RC system fails I still regain control over another radio).
It has a "failsafe" - i=even if it works it's still not really good in an urban area. GPS signals might be weak (flyaway danger) and it's only flies to 25 meters when returning to home. It could fly into a tower or even not reach proper 25 meter when the 3D GPS lock is weak or disengaged.
My 2 cents. Sorry. Please people, don't fly above crowded areas. I've seen a Phantom hit a car it's almost 1KG of deadweight when it comes down. It's only a matter of time until someone gets hurt.
The proof-of-work blockchain transmission means it's the real and proper blockchain and is valid.
You could stop sending new blocks, but that would alarm the endpoint because it will be stuck at block 100 (in our example).
The Proof-of-work scheme is pretty innovative.
Now sending back transactions to the network is not covered, but can be done by using SMS or a small radio link to a local node. A bitcoin transaction is only about 64 bytes (!) so even a DTMF call or SMS should work fine.
A transaction send would look like this (normal TXid, in hex)

That would be 76816061505687581068522220805344294890167166251289478281934616246172205973504
in DTMF. Would take about 15 seconds to complete (http://www.audiocheck.net/audiocheck_dtmf.php)
Is the exploit only for when running services on/to the internet (IIS, Exchange webmail, etc - ) , or is visiting an https (TLS) website on and end-user enough to make the exploit happen (even in Firefox/Chrome and behind a tradional proxy server).
Sadly Microsoft does not explain the exact parameters that make this exploit tick - this makes risk assessment hard.
