From carjack to carhack

As if you didn’t have enough things to worry about when you’re driving… researchers have demonstrated some rather worrying security holes that could allow an attacker to PWN your car’s onboard computer systems by spoofing the signals from the wireless tyre pressure sensors [via George Dvorsky]:

… previous experiments showed what could be done with a physical connection to a vehicle’s computer. The new work by teams from the University of South Carolina and Rutgers tried a different tack: spoofing the wireless sensors in wheels used by tire pressure monitoring systems, required in all new U.S. vehicles since 2008.

The researchers didn’t find a wide-open door so much as the security employed by a 1920s speakeasy: once they learned the secret knock, the unidentified test car’s controls let them in no questions asked. The team sent fake warning messages from 40 meters away, and in another experiment, got the test car to flash a warning that a tire had lost all pressure while beaming the signal from another car as both drove 68 mph.

Because each sensor uses a unique ID tag, it was also possible to track specific vehicles, in a way that would be far less noticeable than roadside cameras.

The hacked car usually reset its warnings after the spoofed messages stopped. But after two days of tests, the electronic control unit for the tire monitors fell off its twig and had to be replaced by a dealer. The researchers note that it took several hours of graduate-level engineering to devise their tools and crack into the monitors, but that the actual technology for doing so cost about $1,500.

Buying off-the-shelf kits to accomplish this sort of hack will be as easy as buying an ATM credit card skimmer or a few hours of run-time on a botnet; it’s just chips and code, after all. And now, would the congregation please join with me in chanting the votive mantra of Futurismic: Everything Can And Will Be Hacked.

Ice Fracture Explorer: theoretical model for a mission to Europa

Joseph Shoer of Quantum Rocketry doesn’t post all that often, but every now and again he puts out a gem. Here he is imagining what you’d need to do to put together a robotic mission to explore Europa, the Jovian moon that’s mostly ocean with a thick icy crust, complete with little diagrams of what the modules might look like:

As Jupiter rises overhead, its tides will pull apart the two sides of the ice fracture. The IFE will be suspended in the middle as the crack opens, with nothing below it until the ocean 1-10 km down! At this point, the IFE will drop its deflated cushions and begin to deploy a smaller penetrator vehicle from its underside. The penetrator is a small, two-stage vehicle with two instrument packages, a hard-shell body, and a data line connecting it to the IFE’s main bus.

Pure hard-SF space geekery of the best type. As Shoer points out, manned missions to Europa are pretty much a non-starter; even if we could get people there, the radiation would roast them pretty quickly. But throw some transhuman moravec explorers into the mix, and you’ve got the start of a great story…

America, the future, empire in decline, Byzantium vs. the USSR, and all that

Experience teaches that writing a convincing near-future sf story is not easy–let alone convincing editors that you are not writing satire–but this really struck a writerly nerve: “Most Americans can’t imagine a future that’s not pretty much like the recent past, maybe with a few wind turbines and solar panels added.”

Jon Talton used to write for The Arizona Republic. Now, as Rogue Columnist, he writes stuff his old bosses wouldn’t tolerate. (He’s published a decent series of crime novels set in AZ, too.) His columns sometimes read like jeremiads, but in the spirit of a couple of Paul’s recent posts about the future of the American empire, here are some snippets from Jon’s latest.  What the hell; it’s Friday the Thirteenth.

I can see a few other outcomes:

1. The man on the white horse. When chaos reaches a certain level most people will eagerly embrace, say, Gen. David Petraeus. He’s shown little MacArthurism in him. But if both political parties and most institutions have lost legitimacy, the military might be forced by events to step in. Or the elites, desperate to save their bacon, might draft this universally admired soldier as president. The move might gain further power as thousands of discharged combat veterans drive the streets of America unable to find work. This will be our Rubicon moment….

[Blogger’s rude interruption: I’m reliably informed that Americans love it when John Wayne rides in to save the day, and in fact many believe it happens on a regular basis, perhaps recently.–Desultorily Philippic Tom]

3. Devolution. This would be another orderly way for a bankrupt and hamstrung federal government to accept reality, particularly if faced with ever greater instability and gridlock. Keep control of national defense, foreign policy, the constitutional basics. And leave the rest to the states, including most taxing and regulatory authority. If Arizona wants to be a law-of-the-jungle toxic dump where the devil takes the hindmost, see how that works out….

4. War with China. …China is happy to watch America exhaust itself in the Muslim world, hoping that will do the trick, leaving America to do a sudden global withdrawal as Britain did. But conflict is not impossible to imagine. If it happened, any of the above scenarios might face a losing America. A greater, if fleeting, imperial moment might await a winning America. But it won’t be the America we once knew.

5. Muslim revenge. The longer we intrude in the Middle East and Afghanistan, keeping armies there, depending on oil from dictatorships, allowing an intransigent Israel to do as it wishes, playing with fire in Pakistan and ignoring all those millions of angry, unemployed young men — the closer we get to a horrific reckoning.

None of this may happen. I certainly don’t want it to happen. But these outcomes are no longer out of the question.

Agree or not, Jon raises issues that sf might arguably and legitimately deal with. Hmm, what was the exact date the world began to look towards China, rather than the U.S., for leadership out of the recession? Am I just a jingoistic ignorant might-as-well-be-a-klansman for even asking if that’s a good or bad thing?

Things are changing pretty fast, has anybody noticed? The author of Russian Spring, with its early cover painting of the Lenin statue greening over, might do a William Windom Star Trek turn: “Don’t you think I know that?!?!” How would a book like Stand on Zanzibar, which I read till it fell apart in my turbulent twenties, read today? (I’ll let you know if I ever track down a copy.) It would be interesting to see stories about how some of Talton’s speculations can be avoided.

Ayn Rand’s PR department: ambitious, unhinged

What do you get when you give an Ayn Rand fan a car with GPS, and a surfeit of spare time and money? The world’s largest GPS graffito, that’s what:

World's largest writing: "read Ayn Rand"

It’s a step up from “Kilroy Woz Ere”, I guess. Heck of an epitaph for a nation, though.
