Presenting Keynterceptor at hack.lu [Luxembourg]

This week I presented my proof of concept USB HID attack called “Keynterceptor” at the hack.lu security conference in Luxembourg. It might not be ground-breaking research, but it’s showing a combination of vectors that have not been publicly disclosed yet. Classic key-stroke injecting devices like the RubberDucky are not very stealthy. With this attack, I intend to be less obvious to detect while being able to bypass known protection mechanisms like USG (hardware), DuckHunt (Windows) and USBGuard (Linux).

Since Keynterceptor is made up from very affordable, off-the-shelf electronic parts, it is likely that such an attack tool can be created and used by someone with few resources. The goal of this presentation it to raise awareness (like many other before me have also done) on the state of trust in our daily devices.

Performance at LMYU Album presentation

Lend me your underbelly (to some known as Christian) did a great job in presenting his awesome album “Hover” at the nice Mirliton theather. Please check out this album at his website www.lendmeyourunderbelly.com, or go to the iTunes store to buy it.


I was one of the lucky people that got an invitation to play at the album presentation. This time I felt like having a more interactive performance by doing some live electronic improvising (Which is only fun btw when your sound card actually works - yes I had some technical problems just before the performance).

Footage might follow later…

littleBits experimenting

I realy like the new DIY-like movement in electronics music that is going on right now

We first had the little Korg monotron synths and Teenage Engineering’s OP-1, now there is littleBits! (which is a bit like “Bloc-Tronic” from the eighties). Korg made a littleBits kit to play with the concepts of modular synthesizers. So I couldn’t resist, check this little experiment.

HITBager - Keysweeper

When Samy Kamkar released his KeySweeper project, I thought to myself… hey I’ve got a piece of hardware that can be reused to play with his code. The so called “Hack In the Box 2014 badge” (aka HITBadger), which has the nRF chip on it!


So I modified Samy’s code to my likes, just to demonstrate (at work) the risk one takes with a wireless keyboard. If you have such a HITBadger, you might try my modification keysweeper_mcu_src.tar.gz. Please note that, Samy’s code has more features.

Study trip CERN

Our study trip to CERN was impressive. I’ve seen one of the Next computer Tim Berners Lee used at CERN to mark the start of WWW (and tried the keyboard, which is a nice experience for a keyboard-nerd like me). We actually got a tour trough LHCb (Large Hadron Collide beauty) experiment and we got a presentation about cyber security from Stefan Lueders (Computer Security Officer).

Paragliding in Genève


This comes close to the real human-flying experience
I had a great time in Genève, like to go there once more…

Love Aphex Twin's Syro album

Check out Richards new Album Syro! It’s what you expect from him, but it has a nice fresh and modern feel to it. I’m so happy

3rd place at Revision 2014 - Oldskool Executable music competition

3rd place at Revision OldSkool executable music I had a lot of fun making “Muhinae-II”, a track for the Sega MegaDrive. The song consists of FM and PSG only sounds, so I didn’t use any samples. Oerg866 helped me out to get the executable to run on the real hardware. He is a great guy!

Revision 2014 was a AWESOME party

Listen here ^ to Muhinae-II

My Magnetic Core Memory module

I’ve got a Core Memory module from a colleague of mine, which is from way before my time
I really see the beauty of these things, so I thought. Let’s share it:

Wikipedia: Magnetic-core memory was the predominant form of random-access computer memory for 20 years (circa 1955–75). It uses tiny magnetic toroids (rings), the cores, through which wires are threaded to write and read information. Each core represents one bit of information. The cores can be magnetized in two different ways (clockwise or counterclockwise) and the bit stored in a core is zero or one depending on that core’s magnetization direction. The wires are arranged to allow an individual core to be set to either a “one” or a “zero”, and for its magnetization to be changed, by sending appropriate electric current pulses through selected wires. The process of reading the core causes the core to be reset to a “zero”, thus erasing it. This is called destructive readout.

SoundChip T-Shirt

"The things that define our style..."

I really felt like dedicating a T-Shirt to my favourite 80’s computer sound chips

SoundChip T-Shirt This is the result… like it?
Okay, it contains more then only sound chips… some machine brands as well!
