Darik’s Boot and Nuke (“DBAN”) is a self-contained boot disk that securely wipes the hard disks of most computers.

DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.

DBAN is a means of ensuring due diligence in computer recycling, a way of preventing identity theft if you want to sell a computer, and a good way to totally clean a Microsoft Windows installation of viruses and spyware.

From cyberguerrilla.info This is a guide with which even a total noob can get high class security for his system and complete anonymity online. But its not only for noobs, it contains a lot of tips most people will find pretty helpfull. It is explained so detailed even the biggest noobs can do it^^ :

=== The Ultimate Guide for Anonymous and Secure Internet Usage v1.0.1 ===

By the time you are finished reading and implementing this guide, you will be able to securely and anonymously browse any website and to do so anonymously. No one not even your ISP or a government agent will be able to see what you are doing online. If privacy and anonymity is important to you, then you owe it to yourself to follow the instructions that are presented here.

In order to prepare this guide for you, I have used a computer that is running Windows Vista. This guide will work equally well for other versions of Windows. If you use a different operating system, you may need to have someone fluent in that operating system guide you through this process. However, most parts of the process are easily duplicated in other operating systems.

I have written this guide to be as newbie friendly as possible. Every step is fully detailed and explained. I have tried to keep instructions explicit as possible. This way, so long as you patiently follow each step, you will be just fine.

In this guide from time to time you will be instructed to go to certain URLs to download files. You do NOT need TOR to get these files, and using TOR (while possible) will make these downloads very slow.

This guide may appear overwhelming. Every single step is explained thoroughly and it is just a matter of following along until you are done. Once you are finished, you will have a very secure setup and it will be well worth the effort. Even though the guide appears huge, this whole process should take at the most a few hours. You can finish it in phases over the course of several days.

It is highly recommended that you close *ALL* applications running on your computer before starting.

Introducing Sandboxie

Sandboxie runs your programs in an isolated space which prevents them from making permanent changes to other programs and data in your computer.

The red arrows indicate changes flowing from a running program into your computer. The box labeled Hard disk (no sandbox) shows changes by a program running normally. The box labeled Hard disk (with sandbox) shows changes by a program running under Sandboxie. The animation illustrates that Sandboxie is able to intercept the changes and isolate them within a sandbox, depicted as a yellow rectangle. It also illustrates that grouping the changes together makes it easy to delete all of them at once.

Benefits of the Isolated Sandbox

  • Secure Web Browsing: Running your Web browser under the protection of Sandboxie means that all malicious software downloaded by the browser is trapped in the sandbox and can be discarded trivially.
  • Enhanced Privacy: Browsing history, cookies, and cached temporary files collected while Web browsing stay in the sandbox and don’t leak into Windows.
  • Secure E-mail: Viruses and other malicious software that might be hiding in your email can’t break out of the sandbox and can’t infect your real system.
  • Windows Stays Lean: Prevent wear-and-tear in Windows by installing software into an isolated sandbox.

TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data is automatically encrypted right before it is saved and decrypted right after it is loaded, without any user intervention.

No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc).

Files can be copied to and from a mounted TrueCrypt volume just like they are copied to/from any normal disk (for example, by simple drag-and-drop operations). Files are automatically being decrypted on the fly (in memory/RAM) while they are being read or copied from an encrypted TrueCrypt volume. Similarly, files that are being written or copied to the TrueCrypt volume are automatically being encrypted on the fly (right before they are written to the disk) in RAM.

Note that this does not mean that the whole file that is to be encrypted/decrypted must be stored in RAM before it can be encrypted/decrypted. There are no extra memory (RAM) requirements for TrueCrypt. For an illustration of how this is accomplished, see the following paragraph.

Let’s suppose that there is an .avi video file stored on a TrueCrypt volume (therefore, the video file is entirely encrypted). The user provides the correct password (and/or keyfile) and mounts (opens) the TrueCrypt volume. When the user double clicks the icon of the video file, the operating system launches the application associated with the file type – typically a media player.

The media player then begins loading a small initial portion of the video file from the TrueCrypt-encrypted volume to RAM (memory) in order to play it. While the portion is being loaded, TrueCrypt is automatically decrypting it (in RAM). The decrypted portion of the video (stored in RAM) is then played by the media player. While this portion is being played, the media player begins loading another small portion of the video file from the TrueCrypt-encrypted volume to RAM (memory) and the process repeats. This process is called on-the-fly encryption/decryption and it works for all file types (not only for video files).

Note that TrueCrypt never saves any decrypted data to a disk – it only stores them temporarily in RAM (memory). Even when the volume is mounted, data stored in the volume is still encrypted. When you restart Windows or turn off your computer, the volume will be dismounted and files stored in it will be inaccessible (and encrypted).

Even when power supply is suddenly interrupted (without proper system shut down), files stored in the volume are inaccessible (and encrypted). To make them accessible again, you have to mount the volume (and provide the correct password and/or keyfile).

Anti-Forensics is a community dedicated to the research and sharing of methods, tools, and information that can be used to frustrate computer forensic investigations.

Subscribe via RSS or Feedburner RSS (Google tracked) and stay up to date on issues and news of interest for the computer forensics and anti-forensics community.

In a nutshell, anti-computer forensics, in the realm of digital forensics or computer forensics, involves the hiding, destroying, and disguising of data.

A major goal of some anti-forensics software, and the focus of Anti-Forensics.com, is to make the analysis and examination of digital evidence as difficult, confusing, and time consuming as possible.

There are numerous uses of anti-forensic tools and techniques. These methods can be used to protect the privacy and the confidentiality of data. This is especially true with disk encryption and disk and file wiping software. Using software to securely delete or wipe data is a method used by criminals, businesses, government agencies, and many individuals concerned in protecting confidential or private data alike.

The most commonly used anti-forensic methods involve:

  • Data Deletion (Wiping)
  • Network Protocol Encryption
  • Data Encryption
  • Physical Destruction of Digital Media
  • Anonyminity Software and Techniques
