Panopticon: A libre, cross platform disassembler for reverse engineering
Great work. Therefore that's one more disassembler in the wide. Some of the great open source ones, reverse oriented, that I have been able to test are:Metasm: https://github.com/jjyg/metasm/Radare: http://radare.org/Capstone: http://www.capstone-engine.org/Capstone is based on LLVM, that you cannot beat in term of architectures and industrial quality, and has great plugins, which make it kind of my favorite.Of course, for non-scripting needs, you need decent graphical interfaces, as provided by these ones:IDA: https://www.hex-rays.com/products/ida/Hopper: http://www.hopperapp.com/IDA is clearly the best, but Hopper is a fair choice if you need it and you can't afford IDA license for personal use.[Edit: add forgotten IDA and Hopper...]
