Embedded Analysis CCC Wiki

I revived the Embedded Analysis wiki entry from 2010 and updated it for the 2014 31C3. The updated version includes some additional information:

  • Finding JTAG by hand Based on the electrical characteristics of contact points on a target PCB one can either reduce the number of pins required for brute force scanning with JTAGEnum or can determine the exact map of JTAG pins. This has reduce the amount of soldering I do for projects drastically.
  • Entropy Analysis of binary blobs Binwalk now includes it’s own entropy graphs. This is noted and show methods for using libdisorder with gnuplot. Also included are entropy graphs of various compression and encryption routines.
  • NAND Dumping code.
