Thank you for you're work. It is very cool and interesting information, but what about real program PWN?
in the real situation there is no such beautiful environment as in CTF's - we have 10 threads and buffer for 64 KB which will be copy to some of vmmap and override a lots of chunks. for example.
so my questions is: how to start study real exploration after i have quite good understanding how memory corruption work?
thank you
There is a typo in lecture 2
gcc -fno-stackprotector .c is wrong, you should write gcc -fno-stack-protector .c
by the way I really liked your lectures (;
Kindly correct typos in explanation of lectures . Thanks.
For some reason this code do not work for me :
for i in `objdump -d shellcode.o | tr '\t' ' ' | tr ' ' '\n' | egrep '^[0-9a-f]{2}$' ` ; do echo -n "\x$i" ; done
And I found that you can use the following code to extract hexadecimal shellcode from the objdump disassemble output :
for i in `objdump -d shellcode.o | tr '\t' ' ' | tr ' ' '\n' | egrep '^[0-9a-f]{2}$' ` ; do printf \\%c%b x $i ; done
