Subterfuge - An Automated MITM Attack Framework

Subterfuge is a very useful tool for hackers and security experts for automating the man-in-the-middle attacks. It provides a complete framework for automating different kinds of MITM attacks.

Subterfuge largely transforms the complexity of performing the man-in-the-middle attacks with the tools such as ettercap and makes it far more easier to launch various form of MITMs. Hence, even a general computer user can perform MITM using this tool. Subterfuge provides a very clear interface accessible over HTTP through browser through which we can view the intercepted authentication data. The tool also supports several other form of MITM attacks such as session injection, http code injection, fake AP, and DNS spoofing.

Currently, the 4.3 beta version of this tool is available as the latest release. You can download the tool and read about the tool at code.google.com/p/subterfuge.

Installation is straightforward. Download the tar file from the above link and then run the following commands in terminal:

samar@samar-Techgaun:~$ tar -xvf SubterfugePublicBeta4.3.tar.gz samar@samar-Techgaun:~$ python install.py -i

After a while, the installation will complete. Now you can run the subterfuge framework by typing subterfuge in your terminal. Enjoy hacking :)

Simple Sorting Algorithm Using DMA

This post provides the source code for simple and naive integer sorting algorithm by exploiting the dynamic memory allocation feature of C programming.

#include <stdio.h>
#include <stdlib.h>

int main()
{
 int *arr, i, j, n;
 
 printf("Enter the number of items: ");
 scanf("%d", &n);
 
 arr = malloc(n * sizeof(int));
 
 for (i = 0; i < n; i++)
 {
  printf("Enter the %dth item: ", i + 1);
  scanf("%d", &arr[i]);
 }
 
 for (i = 0; i < n - 1; i++)
 {
  for (j = 0; j < n - 1; j++)
  {
   int temp;
   
   if (arr[j] > arr[j + 1])
   {
    temp = arr[j];
    arr[j] = arr[j + 1];
    arr[j + 1] = temp; 
   }
   
  }
 }
 
 printf("The sorted array is:\n");
 
 for (i = 0; i < n; i++)
 {
  printf("%d\n", arr[i]);

Java 0-day In The Wild - Disable Java Plugin NOW

Security researchers have discovered yet another critical Java 0-day exploit being used by majority of the browser exploit packs such as Blackhole and Cool. Users are urged to DISABLE the Java plugin RIGHT NOW.

French researcher Kaffeine discovered that the java 0-day has been spotted to be making big hits daily, in a blog post. This particular exploit has proven to be very serious threat for the users. The folks at AlienVault Lab have also reproduced the exploit and it seems to work over all the java versions across all platforms which is a very serious threat.

As for now, the users are highly urged to disable their JAVA plugins right now so that they do not get hit by these 0-days.

So what are you waiting for?

Create Backup Of List Of Apps Installed In Ubuntu

When my laptop's HDD was near to death, I had created backup of the list of all applications and packages I'd installed in my Ubuntu so that I would be able to install them easily in my new system in new HDD. I had forgotten about it but today suddenly remembered and am sharing this simple technique. Fire up the terminal and type the following:

samar@Techgaun:~$ sudo dpkg --get-selections > installed_apps

Now the list of packages will be saved in the installed_apps file and you can use it for future reference. I hope this is useful ;)
