Windows Forensics and Security

By Adrian Leon Mare

The world we live in today is a technologically advanced world. While on one hand, commercialization of IT (Information technology) revolutionized our modern day lifestyle, it has raised a big question mark about the confidentiality and privacy of the information shared and managed using advanced means of communication. As computer technology continues to evolve, the task of managing and handling private and sensitive information is becoming more and more challenging with each passing day. Increased rates of cyber crimes leading to unsolicited invasions of privacy have resulted in the emergence of a new field of computer science known as cyber forensics. With the increasing demand of computer security in recent times, it has become more important than ever to understand the digital forensic technology.

What is Digital Forensics/Cyber Forensics?

Also known as cyber forensics, computer forensics involve the application of acquiring and analyzing digital information (as a part of structured investigation) to be used as evidence in the court of law.

The primary goal of Digital Forensics is to carry out an organized and structured investigation in order to preserve, identify, extract, document and interpret digital information that is then utilized to prevent, detect and solve cyber incidents.

A typical forensic investigation consists of the following main steps:

1. Preserving the data.

2. Acquiring the data.

3. Authenticating the data.

4. Analyzing the data.










Figure 1: Steps involved in a Forensic Investigation Process

1. Preserving and acquiring the data-The first and foremost step of a digital forensic investigation is to preserve and acquire the data from a computer. The step involves creating a bit by bit copy of the hard drive data.

2. Authenticating the data- The next process involves verifying the data seized. To ensure that the acquired data is an exact copy of the contents of the hard drive, the md5/sha1 of the original and copied data are checked and matched.

3. Analyzing the data-This is perhaps the most important part of the investigation process which involves careful examination and analysis of the data using forensic tools.

The process mainly involves:

– Recovering deleted files /Data Recovery

– Tracking or identifying hacking activities

Digital Forensics and Windows

21st century is the century of revolution and change. The transformation of the analog world into a digital world has raised new challenges and opportunities for technology lovers.

New forensic challenges arise with the introduction of newly released and latest operating systems. While on one hand, these newly released versions of Windows are aimed at making things easier for users, many of the functions (such as auto play, file indexing) performed by your operating system for your convenience can actually be used against you.

If you look at the current cyber crime statistics, you will notice that the highest percentage of cyber crimes is committed in the United States of America. 23% of the total cyber crimes take place in U.S. This calls for increased security measures to protect your confidential information from being misused.

The average user is mostly unaware of the fact that their newly upgraded operating system is leaving tracks of their activity. It is essential for users to know that valuable pieces of sensitive and confidential information is stored in Windows Artifacts. These artifacts can be used to recreate and restore the account history of a particular user.

Digital Forensics and Windows-The Windows Artifacts

Some of the artifacts of Windows 7 operating system include:

– Root user Folder

– Desktop

– Pinned files

– Recycle Bin Artifacts

– Registry Artifacts

– App Data Artifacts

– Favorites Artifacts

– Jump lists

Information collected from any of these artifacts can be used to recreate the account history of a user. To gain a better understanding of how these artifacts can be used to access or retrieve valuable information, it is essential to briefly discuss some of the most important Artifacts of Windows 7.

1. Root User Folder artifacts

The Root User Folder gives access to the complete operating system. The Root User reserves the right to delete and modify files on the operating system besides having the rights to generate new users and award them some rights. Nonetheless, these rights cannot exceed the rights of a root user.

The Windows Folder is specified by %SYSTEMROOT%. The Folder can be accessed through Start\Run\%SYSTEMROOT%\System32.

2. Desktop Artifacts

All the files present on the desktop of a user are stored in the desktop folder of the operating system. Typically, the desktop is populated either,

– By the user, or

– By programs that automatically create files and place them on the desktop.

The Desktop can be accessed using the following link;


3. Pinned Files/Jump Lists Artifacts

Pinned Files or Jump lists is a relatively new feature introduced in Windows 7 released by Microsoft. Using the Jump lists all the pinned files can be accessed. Additionally, these lists also maintain a record of recently or last visited files relative to a particular software. Pinned files can be accessed from the jump list using the following link,


4. Recycle Bin Artifacts

The Recycle Bin stores the recently deleted files temporarily. These files can be restored easily. You can only view the Recycle Folder after un-checking the hide\protect system files option using the following link;


5. Registry Artifacts

Registry is the location where the configuration information of Windows is kept and stored. It can be used to obtain information related to historical and current use of applications in addition to obtaining valuable pieces of information about option preferences and system settings. It can be accessed using the following link;


6. App Data Artifacts

Application data or App data is a junction designed to provide backward compatibility. A junction can roughly be defined as a shortcut that serves to redirect programs and files to different locations. All the information related to settings configuration (of various apps) is stored in this folder. Furthermore, information related to the Windows address book and recently accessed files are also stored in this folder. The junction can be accessed through:

C: User\ (username)\AppData\Roamingfolder

7. Favorite Artifacts

The folder contains valuable bits of information related to Windows Explorer and Internet Explorer favorites. The folder can be accessed using the following link;


8. Send To Artifacts
