SparkFun has always been good about designing and stocking useful breakout boards. This recently added Logic Level Converter is no exception. It’s uses two BSS138 MOSFETs to shift 5V logic levels to 3.3V. The board handles two separate serial pairs. Just hook up the RX and TX on either side. Provide power at both voltages and the board will happily do the conversion. It’s $2, smaller than the size of a quarter, and perfect for plugging into a breadboard.

The Last HOPE Full Speaker List Released
The Last HOPE has just released a list of all the schedule talks at the conference. 97 different talks will be divided over three tracks during the course of the three day conference. It looks like a lot of interesting events will be going down. The Cold Boot encryption attack tools will be released. Representatives from Graffiti Research Lab will be showing The Complete First Season and unveiling their One Laser Tag Per Child system. Virgil Griffith from WikiScanner will be mining even deeper into the wretched hive of scum and villainy. Karsten Nohl will present why hardware obfuscation is an impossibility and how they defeated the MiFare crypto. The Last HOPE will be in New York City July 18-20, 2008
Neutering The Apple Remote Desktop Exploit
Yesterday, Slashdot reported a privilege escalation vulnerability in OSX. Using AppleScript you can tell the ARDAgent to execute arbitrary shell script. Since, ARDAgent is running as root, all child processes inherit root privleges. Intego points out that if the user has activated Apple Remote Desktop sharing the ARDAgent can’t be exploited in this fashion. So, the short term solution is to turn on ARD, which you can do without giving any accounts access privileges. TUAW has an illustrated guide to doing this in 10.4 and 10.5.
DecaffeinatID: Simple Security Log Monitor
Irongeek put together a simple program for monitoring network shenanigans when you’re on an untrusted network like the coffee shop. It sits in the Windows Systray and notifies you about a variety of events. It alerts you when it sees the MAC address of the IP gateway change. It watches the security log and warns you of any attempted or successful logins. The firewall log is also monitered. Try it out and send him any bug reports/feature requests you might have.
Hardware FAIL
This forum post from 2005 has us at a loss for words. Please educate your loved ones. Only you can prevent senseless hardware mutilation.

Atari 7800 Portable
Ben Heck has just wrapped up his latest project, a portable Atari 7800. He had meant to do this a long time ago, but lacking experience, the complex looking circuit board scared him off. It features a seven inch display, rechargeable batteries, combination driving and paddle controllers, plus AV out. The console was built by request and just like his other pojects: he’s not shy about showing you how it’s put together. Look for a making-of coming soon.
Firefox 3 Vulnerability
TippingPoint’s Zero Day Initiative reported a critical vulnerability affecting Firefox 3.0 yesterday. It includes the 2.0 versions as well. It’s unreleased and Mozilla is working on a fix already. Whatever the exploit is, it does require the user to visit a malicious site or click a link to executed. It came in 5 hours after the FF3 release, but since it affects previous versions, we wonder if the researcher was just sitting on it to be first. The Zero Day Initiative pays researchers for the exploits they submit.
