Here is the bof program

Code

#include <string.h>

void do_something(char *Buffer)
{
     char MyVar[8];
     strcpy(MyVar,Buffer);
}

int main (int argc, char **argv)
{
     do_something(argv[1]);
}

being learning about bof but got stuck here
tried to insert the address in hex but it kept reading it as asci like EX: AAAAAAAABBBB/*55/*99..
Can someone overwrite the EIP address in here making it point to another location of my choice
thanks
Ironic enough after 5 hours I solved it but you could think of it as challenge to overwrite the EIP in this program

I would expect 5 hours minimum for someone new to stack-based buffer overflows. Congratulations on figuring it out for yourself. If you want to learn more advanced methods on the subject, might I suggest the Corelan Blog. Shellcoder's Handbook and Hacking: The Art of Exploitation are also good books to study it more in-depth.
