In the future this will be possible through pypi.
Make sure you are using python 3.7.
pip install -r requirements.txt
If you have trouble getting thekeystone-enginedependency on Windows (as I did): 1. Clone their repository 2. Open a terminal inbindings/python3. Runpython setup.py install(Make sure you are using python 3.7) 4. Download theirWindows - Core enginepackage here for your python arch. 5. Put thekeystone.dllinC:\location_to_python\Lib\site-packages\keystone\.
3.run python deobf.py - the input ELF to remove obfuscate - output ELF - the trace file path of the target function, which contains the instruction trace, can be collect by ida trace break point.there is an example file tests/bin/data/ins-url.trc - the start offset of the target function - the end offset of the target function - 0/1 is the target function is thumb - <type> [optional] the detector type, not passing is ok for many case
python deobf.py tests/bin/libmakeurl2.4.9.so url.so tests/data/ins-url.trc 0x0000342C 0x00003668 1- This should deobf libmakeurl2.4.9.so JNIONLoad, you can see the output url.so JNIONLoad, has been simplified.
