Remote-Exploit.org is releasing Keykeriki, a wireless keyboard sniffer. The project is both open source hardware and software. you can download the files on their site. Right now you can’t get a pre made board, but they plan on releasing one soon. The system can be upgraded with “backpacks” or add on modules. One of these is going to be an LCD that displays the keystrokes of the keyboard you are sniffing. Another is supposed to serve as an interface to your iPhone. Right now it has the ability to decode Microsoft wireless keyboards, but the Logitech pieces should be added soon.

Wireless Portable USB Tether

USB

[Pete] has put together a fairly simple writeup on building a wireless USB tether for your DSLR. He’s basically using a pair of USB wireless adapters and a battery pack. In his original version, he did some slight modification to the dock that powers the USB dongle, adding his own battery pack too. He notes that this whole project can be done without the effort he put into it, at a little more expense. The only improvement we think would be nice would be a better way to package it to keep it out of the way while you shoot.

D-Link Router Captcha Broken

d-link

We reported last week that D-Link was adding captchas to their routers to prevent automated login by malware. Unsurprisingly, it doesn’t work all time. The team from SourceSec grabbed the new firmware and began poking at it. They found that certain pages don’t require the authentication to be passed for access. One of these is WPS activation. WPS lets you do push button WPA configuration. Once activated, any nearby client can request the WPA key using a tool like WPSpy. Only user level credentials are needed to pull this off, so changing just the admin password won’t prevent it.

GPS Logger With Wireless Trigger

gpslog

[Matthew] sent us his group’s final project, where they built a nice GPS logging system. Not only can it simply log the GPS coordinates on a predetermined interval, it can also be triggered to make an entry by a wireless device. In this example, they use a camera. This allows them to then upload all the GPS information and pictures to places like Google Earth.

They are using an ATmega644, with an LCD, SD card, and GPS unit. They had to do a little hacking on their camera to add the wireless transmitter, which triggers the logger. You can see not only the cost break down and source code for the project, but also a map with lots of geotagged photos. This is the kind of thing we can almost see as a standard item in the future.

weather

This weather monitor can track pressure, temperature, and humidity and last several months on a pack of AA batteries. It has a PIC18f452 to control all the bits, as well as some fancy power management to get the most out of the batteries as possible. The screen displays the highest and lowest temperatures of the last 42 hours as well as having options to display all other sensor input, updated every minute or so. You can get the full schematic and parts list on the project site.

Linksys IP Cam Hacking

admin_password_extraction_2-300x216

GNUCITIZEN has posted information on linksys wireless IP camera hacking. It turns out that some models send the administrator user name and password to the computer when the setup wizard requests a connection. In theory, someone could send the request and harvest your passwords wirelessly. This seems like a pretty careless oversight. We would think that linksys will probably remedy this before too long.

Update: Part 2 has been posted.

RF Modem + 250mW Amplifier

April 2, 2009 by Caleb Kraft 37 Comments

[Trax] sent in his writeup on this RF modem with built in 250mW amplifier. The original power of the RF transceiver was around 10mW, his final results after testing were nearly 250mW. He was able to to easily transmit data over 1000 meters using his test setup. He states that he was actually able to achieve this without an antenna on the receiving side. That’s pretty impressive performance. It’s also worth noting that he soldered all of the components in place using a home clothing iron and some soldering paste. That must have been fairly tedious.
