Help/Support Error In GDB : Anti-debug trick detected

[Amol 0 11]

Hello Guys,

i am constantly getting this error after attaching gdb to the app

Kindly Help me to figure me a wayout.

 

 

i searched for ptrace/syscall in imports (ida) but i couldnt find it either.

Search for ptrace in strings (shift+f12) and if you find a function which has memset nearby, NOP the MOV ...0x1

 

I can't remember it fully.

 

Or get ptrace pwner.

i installed ptrace pwner but still i get the same error as above( anti-debug trick detected)

 

I can attach gdb to process but i dont get any address after setting watch-point

 

however, in ida i get sysctl in Ida but no ptrace or syscall

Zahir hacked it, and he probably used APK compare.
