Computer Forensics Investigation – A Case Study

Computer technology is the major integral part of everyday human life, and it is growing rapidly, as are computer crimes such as financial fraud, unauthorized intrusion, identity theft and intellectual theft. To counteract those computer-related crimes, Computer Forensics plays a very important role. “Computer Forensics involves obtaining and analysing digital information for use as evidence in civil, criminal or administrative cases (Nelson, B., et al., 2008)”. A Computer Forensic Investigation generally investigates the data which could be taken from computer hard disks or any other storage devices with adherence to standard policies and procedures to determine if those devices have been compromised by unauthorised access or not. Computer Forensics Investigators work as a team to investigate the incident and conduct the forensic analysis by using various methodologies (e.g. Static and Dynamic) and tools (e.g. ProDiscover or Encase) to ensure the computer network system is secure in an organization.

Spoofing Ports To Trick Bad Guys

Portspoof is meant to be a lightweight, fast, portable and secure addition to the any firewall system or security system. The general goal of the program is to make the reconessaince phase slow and bothersome for your attackers as much it is only possible. This is quite a change to the standard 5s Nmap scan, that will give a full view of your systems running services.

Web App Pentest - Part 5 XSS

In my previous article we have seen which are the different ways of fuzzing including suffix and prefix. We used those fuzzing techniques in order to find error messages in web application. Now as we know how to fuzz, we will use that skill to find XSS generally known as cross site scripting.

Testing For XSS

Without wasting much time, let us go to, Document viewer page under A3 Cross site scripting(XSS) module. In there are various method of exploiting XSS but first we will choose simple method which is HTTP attribute.

Web App Pentest - Part 4 Suffix & Prefix in Fuzzing

In this series of article, last time we talked about the fuzzing and various SQL statement special characters which can be used in fuzzing the web application. In this article I am going to focus on various prefixes and suffix of fuzzing in order to fuzz the target web application.

Web App Pentest - Part 3 Fuzzing

When We test the web application, we do not test a single page but we test lot of page of a single web application. So each page may have more than one variable so technically you will be engaging with ton of variables within your web application test. So when you inject anything to the input it is good to know what kind of effect your injection is making to the server. In this part of these article series we will look at the importance of simple alphabetic injection along with the web page encoding technology and how it does effect on our testing and result.

Web App Pentest - Part 2 Indentifying Injection Points

If your web page is static, you cannot test it as far as security concern. You can test it at some sort of view but you can’t play with it much as compare to dynamic page. Nikto scanner is a good utility which works best in testing static sites. There has to be some interaction between client and server via login panel, comment section, register page, contact us form and so on.

Web App Pentest - Part 1 Introduction

In this series of articles, I am going to demonstrate how you can manually exploit the vulnerability of a web application, compared to using any automation tool, in order to find vulnerabilities in the application. Almost all companies worldwide focus on manual testing of web application rather than running web application scanners, which limit your knowledge and skills and the scope of finding a vulnerability with your testing.

For the whole series I am going to use these programs:

Different Types of Wireless Attacks - Theory

As we all know that wireless networks are spread at each and every  part of the world starting from personal home to corporate business, schools/universities, cafes etc.. Major merit of wireless network is of eliminating the big and tidy cables which acquires space and not spoiling the look of your working area. But as we all know that each coin has two sides. There are demerits of wireless networks as well. It comes with high possibility of attacks on it. In this article I am going to describe different techniques of wireless attacks from the world and what we should do to prevent those attacks on wireless networks.
