Quickpost: Linux Kernel Joke
A colleague challenged me, half jokingly, to perform a code review of the Linux kernel. I took his challenge: I downloaded the latest stable kernel sources and used a state of the art static code checker (grep -hEir “hack|crack|backdoor|keygen” *).
I located a couple of backdoors:
Some cracks:
And even some keygens:
And the number of hacks was countless (1000+), here is a selection:

A running light with a PIN
We all know the problem, you’ve set-up a running light as Christmas decoration, and then a kid starts changing the patterns you’ve programmed.
But not anymore, I’ve made a running light with security: you need a PIN to access the configuration switches!
The movie is hosted here on YouTube, and you can find a hires version (XviD) here.
Joking aside: I got a set of E-blocks from Matrix Multimedia for Christmas.
E-blocks are a suite of small circuit boards each of which contains a block of electronics that you would typically find in an electronic system. Each E-block performs a separate function as either an input sub-system, an output subsystem or a processing subsystem. E-blocks are connected together using 8 wire buses on 9 way D-type plugs and sockets.
My microcontroller is an ARM board. I develop the embedded programs on my laptop in C/C++, and then transfer the executable to the ARM’s flash memory via USB. Once programmed, the ARM executes the program independently, my laptop is disconnected.
To familiarize myself with the E-blocks, I started programming some simple applications, like a running light. And after that, just for fun, I added security…

Mitigating Risk
I came across an interesting picture while browsing my digital library.
As an IT security professional, you don’t often get a chance to say: “And in this picture, you see me mitigating risk”.

Wardriving on the Eurostar
No big surprise here, I didn’t get a WiFi signal in the Channel Tunnel today. I only logged packets: plenty enough in London, Lille and Brussels, but not in the tunnel.
