I’m trying to exploit a basic C program (below) which I’ve written:
#include <stdio.h>
#include <string.h>
void main()
{
char ch[10];
scanf("%s", ch);
if(strcmp("1235", ch))
printf("\nA… Continue reading Buffer overflow outside gdb
I’m new to buffer overflow exploitation. I’ve written a simple C program which will ask the user to input a string (as a password) and match that string with "1235". If matched then it will print "Access Approved", othe… Continue reading How to do string buffer overflow with scanf function?
I’m following this tutorial to create a buffer overflow demo. The article illustrates a 32-bit executable, but I’m feeling adventurous and decided to do a 64-bit one. Below is the deliberately vulnerable code, and our goal is to call secre… Continue reading Exploiting buffer overflow in 64-bit macOS executable
Code can be beautiful, and good code can be a work of art. As it so happens, artful code can also result in art, if you know what you’re doing. That’s the idea behind Programming Posters, a project that Michael …read more
RSA must be used at the beginning to securely exchange the session keys of
3DES between Alice and Bob.
3DES must be used for encryption/decryption of the exchanged data.
OFB should be used as a mode of operation to transfer the blocks of … Continue reading design and implement a hybrid crypto system that involves 3DES and RSA [closed]
I was trying to learn file I/O and related function in C, and thus tried to create a baby-version of a virus. Following is the exact code:
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
FILE *mod_host, *fin_host;… Continue reading Why does Kaspersky anti-virus not consider this executable as malicious?
Hi guys I’m pretty new to cyber security. Actually I have a bit knowledge around Network Security , CEH topics etc.
So today I decide to learn Win32 in C for Ethical Hacking because I know C and Python. But after few research I saw almost … Continue reading How to use Win32 in C for hacking?

I’m studying the source code of malware developed in c++ and I have two questions in the source code below
This is probably code that loads malicious dlls into memory.
typedef BOOL (WINAPI *VirtualFreeT)(
__in LPVOID lpAddress,
__… Continue reading The hidden meaning of the source code of the malware?
