Reverse engineering for x86/ARM/MIPS binaries. Generate a more readable code (pseudo-C) with colored syntax.
Supported formats : ELF, PE, RAW.
The Makefile is used only for checking tests.
python >= 3.4
capstone + python bindings (see requirements.sh)
python-pyelftools
https://github.com/simonzack/pefile-py3k
terminal with 256 colors (if not use the option `--nocolor`)
For Python binding of Capstone engine, you can install it from PyPi, like followings:
sudo pip3 install capstone
You can also run requirements.sh which will retrieve all requirements.
For every int 0x80, the tool try to detect syscalls with parameters.
$ ./reverse.py --raw x86 tests/shellcode.bin
function 0x0 {
0x0: eax = 0 # xor eax, eax
0x2: al = '\x0b' # mov al, 0xb
0x4: cdq
0x5: push edx
0x6: push 1752379246 "n/sh"
0xb: push 1768042287 "//bi"
0x10: ebx = esp # mov ebx, esp
0x12: push edx
0x13: push ebx
0x14: ecx = esp # mov ecx, esp
0x16: int 128 ; execve(ebx, ecx, edx) # int 0x80
}
$ ./reverse.py tests/nestedloop1.bin
By opening d3/index.html (with the option --graph) you will be able to
see the flow graph :
$ reverse tests/server.bin --data -x 0x400ca0
.rodata [0x400ca0 - 0x400de5]
0x400ca0: 01 00 02 00
0x400ca4: 00 00 00 00
0x400ca8: "Could not create socket", 0
0x400cc0: "Socket created", 0
0x400ccf: "bind failed. Error", 0
0x400ce2: "bind done", 0
0x400cec: 00 00 00 00
0x400cf0: "Waiting for incoming connections...", 0

0x400d51: "accept failed", 0
0x400d5f: 00

0x400d89: 00 00 00
0x400d8c: 00 00 00 00
0x400d90: "Now type something and i shall repeat what you type \n", 0
0x400dc6: "Client disconnected", 0
0x400dda: "recv failed", 0
$ ./reverse tests/dowhile1.bin --vim
You can now run : vim dowhile1.bin.rev -S dowhile1.bin.vim
With the option -i you enter in the interactive mode. See help.
At the first run, reverse.py creates a new file custom_colors.py with
default values. Here you can set your own colors.
