PRTK is widely used worldwide by law enforcement, intelligence agencies, and private corporations such as large financial institutions. In the Q&A below, we get a closer look inside PRTK and the encryption it aims to break.

One of the premier decryption tools on the market is Password Recovery Toolkit (PRTK) from AccessData. Decryption tools are one weapon we can bring to the fight. As such, we must be prepared to deal with encrypted data. Q & A With Nephi Allred, Cryptanalyst with AccessData, the Maker of Password Recovery Toolkit (PRTK)īy now it should be clear that encryption is a major concern to the digital forensics community. Success depends largely on the quality of the tool and the skills of the user. Using these tools is no guarantee that the data can't be recovered. If we want to donate our old computers we certainly don't want our e-mails and other personal information going with it to Goodwill. Privacy is a major concern for everyone, and wiping utilities can help. These tools do have a legitimate use and are available at many technology stores such as Best Buy. They can target specific files and folders as well as potentially incriminating system values like those found in the Windows Registry. Operating system files, for example, could be left intact. They can be somewhat surgical in their application, wiping only specified files while leaving others untouched.
Using these tools is not an “all or none” proposition. Examples of these tools include “Darik's Boot and Nuke,” “DiskWipe,” “CBL Data Shredder,” “Webroot Window Washer,” and “Evidence Eliminator.” Unfortunately, these same utilities can be used for other, less honorable purposes. Most of these applications are promoted and/or intended to keep personal or corporate information private. Drive Wipingĭrive wiping utilities are used to overwrite data on a hard drive in such a way as to make them unrecoverable. Defragmenting or reformatting a drive is frequently attempted, but often delivers limited results. Much of its effectiveness rests with the quality of the software, how it is used, and the number of “wipes” that are made.

Drive wiping software is commercially available and can be effective in destroying potential evidence. Using utilities such as these can leave telltale signs of their use, providing substantial evidence even without the original data in question.ĭata destruction can be accomplished or attempted in several ways. In contrast, many drive wiping tools can be very effective. As we've seen, this approach is not effective because the “deleted” data remain on the media and are easily recovered. The uninitiated may simply hit the delete key, assuming that the data no longer exist. Actually destroying the data is a little more complicated than many people think. Sometimes hiding data isn't enough, and perpetrators try to destroy the data instead. John Sammons, in The Basics of Digital Forensics, 2012 Data Destruction
