Analysing binaries with Binwalk

Wed, 12 Oct 2011 16:24:50 +0000

I came across an interesting tool today called Binwalk.
Binwalk is a firmware analysis tool that scans a given binary file for embedded files and executable code.

Binwalk requires a Linux machine, I used the Backtrack VM I used from my article about WEP keys.

Note there is no binary distribution of Binwalk so you will need to compile it but this is a breeze.

RNS 510 Startup Logo–My thoughts

Tue, 27 Sep 2011 22:13:44 +0000

If you have read my earlier blogs about the RNS 510 then you may know I have been working on creating custom startup logo’s for some time.

For some time now I know how the images are encoded and decoded between Windows bitmap and the native RNS 510 image format.

Recently I identified the checksums in the image data, and the differing parameters for the Seat, Skoda and VW versions of the RNS 510 firmware.

RNS 510 Checksum Calculator

Fri, 20 May 2011 16:42:27 +0000

About a year ago I wrote a checksum calculator for the Volkswagen RNS 510 navigation unit.

The checksum is a variant on Crc16 and is present either at the end of certain files (eg #CRC16:db1d) or as a special file with the name CRC.16.
