Description

Security buy wow gold Fix is just now getting around to blogging about some of the other highlights from the Defcon hacker conference I attended this week in Las Vegas. (I had to recharge my batteries after sleeping fewer than four hours between Saturday and Monday.) I realized I never mentioned a Defcon talk from Friday given by Thomas X. Grasso, who's part of the FBI's National Cyber Forensics and Training Alliance.

Perhaps the funniest and most engaging speaker I've heard from the likes of the FBI, Grasso gave a fantastic talk about what law enforcement really means when it says most cyber criminals running spam, spyware and virus attacks on the Internet today are really just organized crime groups whose turf is the Internet.

This year's Defcon attracted nearly 7,000 attendees, easily a record. One of the contests this year was to see who could come up with the most ingenious hack for the Defcon badges, which this year featured the trademark Defcon happyface and crossbones logo with a pair of alternating flash light emitting diodes for the eyes. A number of people replaced one or both of the blue LEDs with different colors, but others went quite a bit further, like conference attendee "Zane," who fashioned a flamethrower for the smileyface's mouth.

The winning hacked badge was created by Scott Scheferman, an audiophile and DJ who said he wasn't even aware that there was a prize. Scheferman hooked his LEDs up to a homemade synthesizer so that the device emitted an odd array of bleeps and tones along with the flashes, creating a kind of random music. Following Scheferman's demo, atttendees were asked to hold their badges aloft as the lights were dimmed, and the room suddenly swam in a sea of blinking, undulating blue light.

This year's "beverage cooling contest" was a sight to behold (and quite a ball for participants, who wasted no time in sampling the icy drinks). The crown went to Las Vegas locals Bryan and Rob from DC702, who, on their best run, dropped the temperature of a beer from the local 92.5 degrees to 36.1 degrees in about 120 seconds.

One of the highlights of Defcon was the "Defcon Bots" competition, in which different teams competed to build a computer controlled Airsoft gun to shoot down targets, wherein no human control is allowed. Team OCTOPI's setup blasted away the competition, using an infrared laser to snipe 30 targets with 31 shots in true "Terminator" fashion, in less than 38 seconds.

The winning badge was effectively an event generator tapping the +3v from the IC chip to be able to leverage the patterns on board, and run them via an installed 1/4" stereo jack to the modular cwejman synth's envelope generator and LPF cutoff frequency modulation jacks. This allowed for some techno style beats to be produced. There were also some piezo tweeters installed on the badge for proof of concept and troubleshooting. With a little software re programming of the IC, it may be possible to vary the voltage and create a crude VCO out of the badge.
