Scripting radare2 with python for dynamic analysis - TUMCTF 2016 Zwiebel part 2
In part 1 we reverse engineered the algorithm, now we implement a radare2 script in python to recover the flag and defeat the encrypted code.
The code zwiebel.py: https://gist.github.com/LiveOverflow/3bd87ba4ffc48bda07d82eb4223911fa
