I haven’t done anything exciting yet; but here are a few snaps of the innards of the beast.

I won’t mention names, but it seems certain providers seem to favour setting the WPA-PSK passphrase to the phone number of the customer by default.
I have noticed that the ESSID is sometimes a form of the customer surname too.

This is of course dismal security-wise.
Firstly, if I can somehow get the target’s phone number (e.g. looking it up in the phonebook DUH), I can probably just guess the passphrase.

Secondly, even if I have no idea what the phone number is, by using this ‘convention’ for passphrases, the providers have GREATLY reduced the keyspace – making brute force attacks not only possible but practical too.

Let’s take a look at HOT for example. Their phone number-space is 077-XXX-XXXX.
That’s only 10,000,000 possible keys!

The following benchmarks from the Pyrit project paint a pretty bleak picture:

Now I haven’t benchmarked my home system yet, but lets conservatively say that my Radeon HD 5670 can pull a modest 5k PMKs/s I could cover the entire keyspace in 2000s. Statistically speaking, I’d likely hit the key in under 17 minutes!

Pretty practical I’d say.

So basically, providers; please stop doing stupid things like this!

Basically it allows for mapping of the 12 keys to any other (single) keys from userspace.

The module is a bit dirty (and probably buggy), please feel free to improve it!

You can pull it off the GitHub repo: http://github.com/2of1/razer-drivers.

Once you’ve compiled the module you can insert it into a running kernel with ’sudo insmod hid-razer.ko’.

Before the kernel will load the module code when you plug in the device, you’ll need to compile a custom version of the hid module.
You basically need to add an exception for the Naga device to hid-core.c to cause the module to load the driver instead of defaulting to the regular HID code.

I simply added (on line 1290 of Ubuntu’s 3.0.0 kernel sources):

static const struct hid_device_id hid_have_special_driver[] = {
    { HID_USB_DEVICE(0x1532, 0x0015) },
    .
    .
    .
}

To change the key mappings from userspace, you can change the values of key1-key12 in the sysfs driver tree:

$ tree /sys/bus/hid/drivers/razer/0003\:1532\:0015.0004

You need to use key values as they appear in the kernel input device header <linux/input.h>.

I stupidly didn’t take photos during the construction and seriously messed up the paint job.

But anyway this is what it currently looks like without the electronics:

You can see the scale of it (that thing on the right is the gas stove).

After contacting Victor for some pointers (he’s extremely helpful), I’ve started the design for my Namco arcade machine (basically a GBA SP running ‘Namco Museum’ in a fancy housing).

It’s to be constructed out of 6mm MDF. I’ll need to send it in somewhere (probably a company the UK) for routing as I don’t have a CNC (does anyone know anywhere in Israel that can do this at a reasonable cost including the wood?).

I’ve already got the buttons, etc. and will post a few pics and specs in my next post.

Quite a few scrunched-up pieces of paper later, and here’s what I’ve got so far for the housing.

All the pieces for the housing



Control panel (joystick + controller buttons)



‘Coin door’ panel (select and start buttons)



Back panel (power and screen backlight buttons)

The hashtable uses char * for keys, allows any type of data to be stored, allows for an arbitrary size and uses linked-lists for collision handling.

Now of course you can install it in a VM, but what’s the point? A x86_64 can natively run 32-bit instructions can’t it?!

Getting IDA Pro up and running involves quite a few steps. Here’s how it’s done on Arch Linux.

32-bit chroot environment
This first thing to do is get a minimal 32-bit chroot environment going.
There are a number of ways of doing this (in fact, there are a number of ways of doing almost everything in this post).
The easiest is probably by installing the arch32-light package from the AUR:

pak -S arch32-light
sudo arch32initialize
sudo pacman32  -Sy bash coreutils filesystem grep gzip licenses sed
sudo pacman -S schroot

(NOTE: I use paktahn to install Arch Linux packages as to includes support for all repositories – including AUR – and has a ‘pacman’-esque command format feel to it; but please feel free to use whatever method/frontend you want)

You should now have a fancy, albeit minimal, 32-bit chroot environment set up.

Installing IDA Pro
Now you can go ahead and copy IDA Pro somewhere.

mkdir ~/tools/ida
tar xvf ida_XXXXXXXXXXXXX* -C ~/tools/ida

Getting IDA to execute using
We now need to install a number of 32-bit dependencies for IDA (./idaq) to run:

sudo pacman32 -S glib2 freetype2 ttf-dejavu libsm libxrender fontconfig libxext

IDA needs to connect to the host (64-bit) X-Windows server.
Access control is enabled by default, so simply give access to local clients:

xhost +local:

Give it a go!
You should now be able to take you IDA install for a spin:

schroot -p ./tools/ida/idaq

What you’ll notice is that idapython can’t dlopen() libpython2.6. Simply installing python2.7 in the chroot environment (with pacman32) or even installing python 2.6 from the AUR doesn’t seem to work (creating a symbolic link from 2.7 -> 2.6 is a no go either).
You can either compile a 32-bit, python2.7 version of idapython or ask/wait for one to be released.
