Tutorial Hacking with GDB Breakpoints

MeSailesh7 · August 22, 2018

just a noob question..... As I can remember Laxus told me we can use write(set) also in GDB but I haven't tried it ...if it works it might be more easier then tweak inject..so to use to write do I need to do aslr-slide for that also?

This is from shmoo's github page:

- add-aslr-set: a command to automatically add the ASLR slide to the expression in the set command. To use, set add-aslr-set on. Since memory addresses already have ASLR accounted for, we need an upper bound to know when to not add the ASLR slide. Use 0x103000000 if you know you aren't going to be modifing memory and only instructions, otherwise, use IDA Pro to find out where main code segment ends (Ctrl+S)

Got it Boss...thanks for the clarification , highly appreciated

but I Think GNU debugger has some problem in ios 11.3.1 because when when I attach PID and continue and enter it doesn’t show (gdb) in terminal it only says continue and then I can’t enter any command and have to force close terminal aka “X” button. Anyway I will ask shmoo about it...

Interesting topic, I'm glad that I found it. This might be a great theme for assignment writing and click for more information to know how to do this. Hacking with GDB breakpoints is a hot topic nowadays so this should be an interesting assignment writing for me. At least this topic is interesting to read and I hope to find more opinions on this issue.
