Pintool

This tool can be useful for solving some reversing challenges in CTFs events. Implements the technique described here:

Configuration

You must configure your pin PATH inside of script

PIN = "./pin-2.13-62732-gcc.4.4.7-linux/pin"
INSCOUNT32 = "./pin-2.13-62732-gcc.4.4.7-linux/inscount0.so"
INSCOUNT64 = "./pin-2.13-62732-gcc.4.4.7-linux/source/tools/ManualExamples/obj-intel64/inscount0.so"

Help

$python pintool.py 
usage: pintool.py [-h] [-e] [-l LEN] [-c NUMBER] [-b CHARACTER] [-a ARCH]
                   [-i INITPASS] [-s SIMBOL] [-d EXPRESSION]
                   Filename

positional arguments:
  Filename       Program for playing with Pin Tool

optional arguments:
  -h, --help     show this help message and exit
  -e             Study the password length, for example -e -l 40, with 40
                 characters
  -l LEN         Length of password (Default: 10 )
  -c NUMBER      Charset definition for brute force (1-Lowercase, 2-Uppecase,
                 3-Numbers, 4-Hexadecimal, 5-Punctuation, 6-All)
  -b CHARACTER   Add characters for the charset, example -b _-
  -a ARCH        Program architecture 32 or 64 bits, -b 32 or -b 64
  -i INITPASS    Inicial password characters, example -i CTF{
  -s SIMBOL      Simbol for complete all password (Default: _ )
  -d EXPRESSION  Difference between instructions that are successful or not
                 (Default: != 0, example -d '== -12', -d '=> 900', -d '<= 17'
                 or -d '!= 32')
