The National Science Foundation (NSF) is funding the University of
Arizona in developing a project they call the Dark Web to track down
terrorists on the net.
When I read the NSF press release that my friend Randy A. pointed out to me, I could have sworn some of it was describing chapters of The Dark Net.
"They
can put booby-traps in their Web forums," Chen explains, "and the
spider can bring back viruses to our machines." This online
cat-and-mouse game means Dark Web must be constantly vigilant against
these and other counter-measures deployed by the terrorists.
Dark
Web's capabilities are also being used to study the online presence of
extremist groups and other social movement organizations. Chen sees
applications for this Web mining approach for other academic fields.
"What
we are doing is using this to study societal change," Chen says.
"Evidence of this change is appearing online, and computational science
can help other disciplines better understand this change."

Cyber Attack blows up a Generator
CNN is reporting
that the Department of Homeland Security managed to blow up an
electrical generator in a simulated cyber attack. It's a vivid
demonstration of how the growing dependence on networked control systems
links virtual world actions with real world effects.
This shouldn't really surprise anyone. Power grids are already too complex and interconnected to be controlled in any way other than by remote networked systems. Heck, pilots don't really fly jets much anymore - they just use the stick to tell the computer to take the plane in a particular direction. In fact, I doubt planes will even have pilots in 50 years, they'll be just like the automated trams that already haul people around on the ground at airports.
I can currently monitor my home through a web cam, and it won't be long before I have the ability to turn on the lights remotely and crank the air conditioning or heat from the office so things will be nice an comfy when I get home. Someday, I imagine someone could hack my house and do all sorts of annoying things. And if someone were to hack a plane, train, hydroelectric plant, or a nuclear power plant, things could get bad pretty quick.
The experts in the CNN story say that "a lot of the risk has already been taken off the table, " by finding ways to prevent the transformer hacks, but that it could take months to fix them all. That means our power grids are suffering from a classic zero day vulnerability. That is, the powers-that-be have publicly pointed out the flaw and announced fix, but anyone with the motivation has plenty of time to find unprotected systems to attack.
An expert interviewed on CNN claims that shutting down power to 1/3 of the country would have the economic and social devastation comparable to the nation being simultaneously hit by 40-50 major hurricanes.
Will there be an attack? Probably not. On the other hand, this is just one vulnerability. No doubt every networked machine or system, just like every networked computer, will eventually face similar threats.
