This is the repository of the codes used in the sessions for Binary Exploitation 101. To compile any of the C source files, the following flags for gcc will be useful.
gcc -z execstack file.c
This remove the NX bit and allows the execution of shellcodes from the stack.
gcc -fno-stack-protector file.c
This removes stack canaries.
If you want to remove ASLR (Address Space Layout Randomization), edit the file
/proc/sys/kernel/randomize_va_space
to do that, execute:
sudo vi /proc/sys/kernel/randomize_va_space
press r0 and then :wq. Then hit Enter.
The python scripts will need pwntools.
To install the library, run pip install pwntools.
