I have following code:
#include <stdio.h>
#include <stdlib.h>
int main()
{
int *ptr1 = malloc(16);
int val1 = 0x12345678;
printf(“stack: %p\nheap: %p\n”, &val1, ptr1);
return 0;
}

I’m doing a buffer overflow challenge, and I can’t understand what exactly I’m doing wrong. Through debugging, I managed to figure out how my input should look like such that I can force the program to return to a function. From gdb I figu… Continue reading Understanding why this buffer overflow attack isn’t working
Does C++ has something similar to Java BigInteger, or what is the best way to store arbitrarily big integers in C++? Java BigInteger claims support of Immutable arbitrary-precision integers and
support values in the range -2^Integer.MAX_VA… Continue reading big integer in C++ [closed]
I’m learning about format string exploits, and am attempting to use one on an example program to overwrite the .fini_array section in virtual memory with a stack address containing shellcode (and hence redirect execution to the shellcode o… Continue reading Writing to .fini_array
I was trying out a CTF called “buffer overflow 1” from picoCTF which for some reason doesn’t work. I found the offset and entered the address to which function should be executed as the return address, however, it always points to another … Continue reading simple buffer overflow does not work even though I give it the correct bytes as input in the EIP
What if a person say that I don’t want to be the drake of all trades. I just want to learn one language to be a cybersecurity professional that it can do anything from hardware to software to anything related to internet. Writing script al… Continue reading C or Python for cybersecurity of all kind?
I would like to know if a simple malware designed to execute commands received by a C&C will have the same result rate if programmed in :
lower-language like C++
high-language like Python (converted to executable with a Python conver… Continue reading Is malware programmed in high-level language will be more detected than malware programmed in low-level language?
I have an interview where I am expecting to have to review some vulnerable C code and point out the vulnerability(s). I am by no means a C developer, but I do know that the common vulnerabilities are primarily related to how developers man… Continue reading C Security Code Review
