Those magnificent men with their hacking machines

Ah, that age-old problem: you’re wandering around with your laptop trying to steal Wi-Fi, hack into wireless networks, or just hit some sucker with a DOS attack, but then you find your potential victim lives in a huge mansion with grounds so big you can’t get within range of his router.

If you’re just messing about, you’ll probably relocate to a coffee shop where it’s easy pickings. But if you’re a little more ambitious, well, why not bring in a small plane.

Yes, unmanned drones are no longer for bombing enemy combatants or sneaking illicit video footage. Two security researchers have now shown they can be adapted for very literal wireless hacking.

Richard Perkins and Mike Tassey told the Black Hat security conference how they souped up a $300 drone with a gadgetry including a video camera, a Wi-Fi dongle, and even a miniature antenna that can pose as a GSM cellphone tower to intercept calls. The drone even has an electronic dictionary of 340 million words in case a brute force attack is needed to find a password.

While the drone is legally required to stay under 400 feet, the creators say that’s high enough, and the device quiet enough, that it could fly overhead without necessarily attracting attention. According to Perkins and Tassey, all the equipment used on the drone was purchased legally. One drawback is that it must be in the line of sight for take-off and landing, but can be put on autopilot while airborne. It has a flight time of 30 to 45 minutes.

The pair say they built the drone to show the potential security risks if more criminally minded people used the same tactics. But they do say it could be used for military purposes, such as relaying messages or jamming enemy signals, as well as legitimate civilian life purposes such as providing emergency cellphone access after a natural disaster.



Antiproton Ring Found Around Earth [Science!]

Good news for the people responsible for fueling future spacecraft–a ring of antiprotons has been detected spiraling between the Van Allen belts. Theoretically, the antiparticle equivalent of protons could be used to power super-efficient rockets. “This is the most abundant source of antiprotons near the Earth,” says Alessandro Bruno,  of the University of Bari in Italy. “Who knows, one day a spacecraft could launch then refuel in the inner radiation belt before travelling further.”

Charged particles called cosmic rays constantly rain in from space, creating a spray of new particles – including antiparticles – when they collide with particles in the atmosphere. Many of these become trapped inside the Van Allen radiation belts, two doughnut-shaped zones around the planet where charged particles spiral around the Earth’s magnetic field lines.

Heavier particles take wider paths  around the planet’s magnetic lines, whereas lighter particles, like positrons (the antiparticle’s answer to electrons) make nice, regular spirals. We already knew there were positrons  in the radiation belts, but at nearly 2000 times as massive and lacking evidence of any antiproton cloud hanging around the Earth, antiprotons were thought to be weighty enough to get pulled into the atmosphere, where they’d collide with normal matter and annihilate. But the cosmic-ray detector PAMELA has confirmed that the Van Allen belts work in a way similar to magnetic traps  to hold antiprotons for minutes or even hours before they inevitably meet normal matter and cease to exit.

Between July 2006 and December 2008, PAMELA detected 28 antiprotons trapped in spiralling orbits around the magnetic field lines sprouting from the Earth’s south pole (Astrophysical Journal Letters, DOI: 10.1088/2041-8205/737/2/l29). PAMELA samples only a small part of the inner radiation belt, but antiprotons are probably trapped throughout it. “We are talking about of billions of particles,” says team member Francesco Cafagna from the University of Bari in Italy.

Twenty-eight antiprotons sounds like nothing, really. But that’s actually a pretty substantial quantity, and verifies the hypothesized but not-yet-evident theory that such a ring might exist. So it looks like now all we need are those super-efficient rockets, Science.

The Atlantic’s Google Earth Puzzle

The Atlantic’s In Focus with Alan Taylor is running a fun thing — the Google Earth Puzzle. You get 25 really spectacular images with vague clues (the one for the image above reads “This community lies near the intersection of seven rivers.”) to their location. The challenge is to figure out where each one is taken. The answers are at the end of their post, but it’s much more fun to actually try to do it yourself. Go check it out, and good luck!

Otakon 2011 Cosplay [Gallery]

Otakon 2011 took place from July 29th to July 31st again this year, and as usual, thousands of costumed fans descended upon Baltimore to celebrate all things anime, manga, and Asian pop culture. As we did for SDCC 2011 (Click!), we searched flickr for some of the best CC-Licensed cosplay photography of the event and assembled them in the photo gallery you see below. Enjoy!

Facebook Profile Dress Fail [Pic]

This Facebook profile dress comes from Romanian designer Lana Dumitru. Now that you’ve seen this, here’s how you too can become a world famous designer in 4 easy steps:

1: Print your Facebook profile over a large sheet.
2: Wrap yourself in it!
3: ???
4: ART!

As far as I’m concerned, I much prefer the Magic: the Gathering dress we’ve featured a while ago.
