I find it hard to accept "mere coincidence" in the two recent spat of crane collapses in New York City, the one recent crane collapse Miami, and elsewhere across the country.  At least nine (9) cranes have recently collapsed in America, most of them deadly.

I placed a phone call to a very high ranking former supervisor of mine who now works at Air Force Cyberspace Command.  "You're absolutely right to disbelieve the coincidence of it all," he assured me.  Chinese military hackers have repeatedly attacked the Supervisory Control and Data Acquisition (SCADA) systems on today's high-tech cranes.

"We're losing lives in the U.S. and no one seems to care," my former supervisor said in disgust.  "We can't even get Congressmen from New York to listen to us.  They just want to blow more money on physical security when we can prove beyond a shadow of a doubt that China is toppling cranes on our apartment buildings from the comfort of their Beijing cubicles."

When I asked my former supervisor for details on the specific techniques the Chinese used to attack our construction equipment, he told me it's all highly classified but he did mention it's based on a bunch of zero-day exploits the Chinese have discovered in recent months.  "The Chinamen are at least three years ahead of us in SCADA exploits," he admitted.  "The folks in Idaho [who do classified SCADA vulnerability research for the Department of Homeland Security] have a lot of catching up to do."
