Help/Support [HELP] Remote debugging iOS apps with debugserver and IDA PRO

[fjfc 0 31]

Hi, I'm trying to debug an iOS app with debugserver and IDA remote gdb debugger with no success, I managed to attach to it using lldb just fine, but when it comes to IDA it does not work, here are the steps I'm taking:

 

I dump the binary using Clutch, open it on IDA,

 

on iOS device run debugserver and attach to the runnig process: debugserver *:1234 --attach=pid

 

on IDA set debugger to remote gdb debugger and set ip and port of my idevice.

 

when I try to attach to the debugserver using IDA it is crashing with error:

 

 

Can any1 help please?

You need to use winscp or cyber duck to do the LLDB/GDB instead of IDA

 

Look in tutorial section

You can use WinSCP to transfer binaries, files, etc from your phone to your computer.

 

You should use PuTTy for debugging. The method you are trying to do does not work I think.

Are you 2 guys sure? I think this guy in this thread got IDA to work with gdb remote debugging:

Because its same thing. You just need to look at offset in gdb/lldb then search for it in IDA

Never tried it, so I don't know. always used PuTTy.
