Twitter As A Botnet Command Center

August 26, 2009 by Matt Schulz 7 Comments

The folks over at Arbor Networks were browsing Twitter and discovered something very strange: a Twitter account seemingly posting gibberish. At least, that’s how it appeared at first. Upon closer investigation, they discovered that the profile was posting base64 encoded links to PKZIP archives. When they extracted the contents and unpacked the contained DLL and EXE files, they discovered that the account was posing links to malware that would post user information back to certain URLs. The article was also updated to show that the scheme wasn’t limited to Twitter, but also affected users on Jaiku and Tumblr. It’s a bit scary to see that all malware isn’t as blatantly obvious as we usually would think it to be.

Open-Frame Digital Clock

August 26, 2009 by Caleb Kraft 13 Comments

Here’s an interesting project from several years ago. The clock design itself isn’t too noteworthy, but the construction is definitely inspired. You’ll notice that there is no breadboard or PCB, the frame actually is the circuit. The tubes he’s using are Numitron tubes, which aren’t as high voltage as Nixies or even VFDs. This means that there is only 12V maximum going through the exposed rails. He discusses some possible future upgrades such as LED or Nixie or VFD, but since this project is a few years old, who knows if he is still working with it.

SpiderBot Emulates Spider-man

Spiderbot moves with four magnetic grapplers that it can launch, detach, and aim according to it’s path planning algorithm. While the robot is definitely not a final product and is quite a bit away from moving with the same grace and speed as our friendly neighborhood Spider-Man, it is definitely one of the more interesting locomotion experiments out there. The video has some nice slow motion footage of the main mechanisms as well as screen captures of the path planning.

HTPC Inside A Cellular Phone

Reader [Jani] always wanted to throw a PC into an old school cell phone. He based this around the extremely small Commell LS-371 motherboard which measures just 146×101 mm (~5.9×4 in). He found room behind an existing access door for a DVI connector and audio in/out. He even incorporated an OLED screen, secondary sound card for “speakerphone”, and a WiFi connector into the handset. Things start to get interesting when he decided the SSD was too large and needed to be removed from its case. The one thing that seems to be missing here is an IR receiver for a remote but since he plans on running XBMC, he may already be setup to use another option such as an iPhone to act as a remote interface.

Single Can Mini Fridge

What looks like a potential WMD, requires a huge power supply, and has several fans and wires dangling off the sides? Why a mini fridge of course! Your cubical buddy at work may have a Perfect Coffee Mug, or a USB powered fridge but it wont be as large of a caliber as [CaptPikel’s]. Little information about it is out thus far, but an Instructable is promised. We do however know that it uses 3 peltier coolers (assumed to be 60watt each) and can cool down to 46F while being underpowered! If only it held just a few more cans.

Arduino Based Synthesizer

[Jacob] is working on his final project for the Copenhagen Institute of Interaction Design. Based around Arduino, the quality and quantity of his build notes make this a fascinating read and there are several examples to listen to.

The project features a brilliant idea for input: He uses a 1/8″ TRS connector (mini-jack) whose tip is the input to the DAC of the Arduino. There are conductive pads in the shape of a keyboard that you touch the tip of the connector to in order to complete the circuit. Alternatively, the other two conductors on the connector deliver power and ground for easy interface with external controllers. He built an example controller that uses an LED and photoresistor to alter the signal returning to the Arduino. Put your hand in front of the light and the sound changes.

BlackBerry Storm 2 Teardown

Photos of the BlackBerry Storm 2, both inside and out, have been leaked. Engadget provides us with the specifics, going into detail about the four large piezoelectric pressure sensors that sit underneath the screen. It looks as though the screen will still function as a button, just without the physical movement of the previous model that received mixed reviews. For a better explanation of the technology behind the phone’s innovative screen, here’s a video describing it in more detail and a writeup over at the CrackBerry forums.
