I use hopper disassembler to disassemble iOS apps. It works fine for most of the apps.
However today I just got curious to understand a banking app so I tried to disassemble it. So, I moved the app from my jailbroken device to my mac and when I tried to disassemble it with hopper it just gives me some useless stuff.
Why is this happening? Is the binary of this banking app encrypted? If yes then how can I decrypt it?
What do they exactly do to obfuscate code ? How does their code differs from other applications code ?
I used iFunbox to get executable of app from my iPhone to my mac. All apps exported in this way have no problem while disassembling. So i think iFunbox does DRM removal. Only this particular banking apps does n't work.
I even tried class dump and it gave me only one file named CDStructures.h with nothing in it.
