Smartphone anti-virus software

cracked

With DEFCON and Black Hat going on, a lot of security issues are being made public. This year, cellphones have been a larger target than before. More and more people are carrying complex smartphones that have more ways to go wrong. Even worse, since phones are tied to a billed account, it is possible for malicious software to charge phones discreetly. However, Flexilis promises to keep your phone safe. It’s a free mobile anti-virus that works on most smartphones and PDAs with more clients in the works. It also provides easy backup and recovery options, as well as the ability to wipe the phone if it’s lost. The phone makers really need to fix the probelms, but in the meantime Flexilis can provide a quick response.

Defcon 17: Badge details released

humanbadge

Defcon is upon us once again, and that can only mean one thing: new badge designs. Our friends over at Wired posted the picture above along with a description of this year’s new badge. Since our last post, there has been little new information released regarding the components used for the new badge. However, we now know that it utilizes a microphone and a full color LED along with the Freescale mc56f8006, an¬†advanced digital signal processing microcontroller. [Grand], the badge designer, told Wired that while this year’s design is a bit simplified compared to last year’s design, it is not nearly as easy to hack. Just like last year, the functionality of the badge hasn’t been announced yet. We’re hoping for some kind of communicator. Be sure to check out Wired’s article if you want to see the high res pictures.

DENCON

Defcon, the world’s largest hacker convention, is this coming weekend in Las Vegas. While the convention generally focuses on breaking new technology, digital archivist [Jason Scott] has an interesting surprise for attendees this year. With some help from VintageTech, he’ll be assembling a massive den of retro computing machinery. They’ll have fully functional systems like the PDP-11/70 for people to play with. It sure to be one of the more unique things to see at the con.

Defcon 17: early badge details

Every year, the Defcon badge takes a technological step forward. The details are starting to emerge for this years hardware lineup. Last years badge, pictured above, had LED status indicators and an IR transceiver. There’s no telling what this years badge will do, but we do know it has a new processor. They have chosen the Freescale MC56F8006 to build everything around this year. We think it would be cool to see some RFID, maybe a heat map of the traffic in the facility. Maybe some distributed computing would be cool. What could we do with an embedded camera? We eagerly await more details.

Binary reversing comic

Last month, in preparation for Defcon 17, the qualifiers were held for capture the flag, one of Defcon’s most well known events. One participant, [mongii], did a writeup on how to solve problem B300. The challenge was to find the decryption key used by a program that had several twists that hindered debugging. After grappling with self-modifying code and junk instructions, the team was finally able to find the answer. This win helped Sapheads place in the top 10.¬† Over at xchng.info, they are collecting solutions to the other problems. Sadly, they’re not all in comic form.

Defcon 17 Call for Papers

Notorious hacker conference Defcon has just published their Call for Papers. The 17th annual event will happen July 30th through August 2nd. Most of the announcement is the same boilerplate they’ve included for the past two years. Like last year, they’re not defining the specific speaking track themes and will come up with them based on submissions. New for this year is a half-day of workshops on the Thursday before Defcon for anyone that’s showing up early. This pre-con event is targeted at newbies. It certainly sounds like an interesting way to ease into Defcon instead of the usual delays and fire marshals. We’ve been attending every year since 2005 and love seeing new things. You should definitely consider presenting this year (we want to see more hardware!).
