Furthermore, major software are analysed using the same way,but just get a bit complex in the methodology. This tutorial is intended for those who are new to reverse engineering and disassembling.

GNS 3 Tutorial – Basic Router password Configuration

Hi folks..I have started my first steps into Cisco, & would be sharing my small experiments in it. Actually , this time I am  covering the basics using GNS3 which is a powerful open source network simulator to simulate a simple topology of 2 routers with their basic configuration & commands. I assume you have worked with GNS3 or atleast know how to load IOS & make a simple topology..
So, firstly download GNS3 & install it. Get IOS images from and load them (if you are really not sure of this step, mail me, I will expand the basics more)
The topology I created is this -

Create a Zip Bomb - Zip of Death

A zip bomb, also known as a Zip of Death, is a malicious archive file designed to crash or render useless the program or system reading it. It is often used by virus writers to disable antivirus software, so that a more traditional virus sent afterwards could get into system undetected. A zip bomb is usually a small file (up to a few hundred kilobytes) for ease of transport and to avoid suspicion. However, when the file is unpacked its contents are more than the system can handle.You can make your own zip bomb to annoy your friends or just out of curiosity (or wilderness) to experiment with it. Make sure you don't detonate it on yourself.

A simple tutorial on Remote File Inclusion (RFI)

RFI stands for Remote File Inclusion, and it allows the attacker to upload a
 custom coded/malicious file on a website or server using a script. The vulnerability  exploit the poor validation checks in websites and can eventually lead to code execution on server or code execution on website (XSS attack using javascript). This time, I will be writing a simple tutorial on Remote File Inclusion and by the end of tutorial, i suppose you will know what it is all about and may be able to deploy an attack or two.
