Buffer Overflow Example
This is an example of a very bad coding practices that introduces a buffer overflow. The purpose of this code is to serve as a demonstration and exercise for The Art of Hacking Series and live training
#include <stdio.h>
void secretFunction()
{
printf("Omar's Crappy Function\n");
printf("This is a super secret function!\n");
}
void echo()
{
char buffer[20];
printf("Please enter your name:\n");
scanf("%s", buffer);
printf("You entered: %s\n", buffer);
}
int main()
{
echo();
return 0;
}
The char buffer[20];
is a really bad idea. The rest will be demonstrated in the course.
