Counter-Forensic Privacy Tools a Forensic Evaluation
Counter-Forensic Privacy Tools A Forensic Evaluation Matthew Geiger, Lorrie Faith Cranor June 2005 CMU-ISRI-05-119 Institute for Software Research, International, Carnegie Mellon University School of Computer Science Carnegie Mellon University Pittsburgh, PA 15213-3890 Abstract Modern operating systems and the applications that run on them generate copious amounts of data about their users’ activity. Users are increasingly aware of their privacy exposure from these records and from digital artifacts that linger after files are “deleted” on computers they use. Efforts to redress this privacy exposure have spawned a range of counter-forensic privacy tools – software designed to irretrievably eliminate records of computer system usage and other sensitive data. In this paper, we use forensic tools and techniques to evaluate the effectiveness of six counter-forensic software packages. The results highlight some significant shortfalls in the implementation and approach of these tools, leading to privacy concerns about the exposure of sensitive data. The findings also raise questions about the level of privacy protection that is realistic to expect from these tools, and others that take a similar approach.

There has been the development of both commercial and freeware data erasing tools, which all claim complete file or disk erasure. This report analyzes the efficiency of a number of these tools in performing erasures on an electromechanical drive. -

Magnetic Data Recovery 1
Magnetic Data Recovery 1 Running head: MAGNETIC DATA RECOVERY – THE HIDDEN THREAT Magnetic Data Recovery – The Hidden Threat Joshua J Sawyer East Carolina University Magnetic Data Recovery 2 Abstract In presenting the dangers of magnetic data recovery, this paper gives the reader a descriptive, yet active view. The methods themselves are described, as well as possible avenues of action that can be used to prevent and mitigate this type of security breach via real-life examples from the field. The primary target of this paper is the business / corporate manager. However, the analysis given will also apply to the home user, and anyone else wanting to ensure that their sensitive data is not at risk. The concepts discussed here should be considered mandatory knowledge for those who seek to safeguard their personal information or that of their employers from unauthorized disclosure and abuse. Magnetic Data Recovery 3 Magnetic Data Recovery – The Hidden Threat The majority of today’s businesses rely in some way upon computer systems to handle the tasks of everyday commerce. These businesses are increasingly using computers to work with their internal and external documents, depending more and more on digital storage every day. Most attention has been focused on well-known problems such as viruses, exploits, etc. Attacks by intruders and insiders have led to billions of dollars in lost revenue and expended effort to fix these problems (Freeman, Long, Miller & Reed, 2001, ¶1). For the most part, these attacks have been focused on software based vulnerabilities, while perhaps the most devastating vulnerabilities lie in hardware devices which exist in the majority of all computer systems in use today. -

Truly Deleting Files Lorrin R. Garson
Truly Deleting Files1,2 Lorrin R. Garson NOTE: Thoughtful caution should be exercised before downloading, installing and running any software… perhaps extra caution with programs that purport to over-write files and/or “clean up” the Registry. Only download software from trusted sources and seek independent reviews of software before attempting to use. The author of this document has not tested any of the software cited, does not endorse any of these products and services and accepts no responsibility for their use. Background: When a file is deleted from a disk drive, even deleted from the Recycle Bin, data in that file remain on the disk drive. The deleted file is marked as “deleted” in the master file table (MFT) and clusters allocated to the deleted file are marked as “free” in the file $BitMap (each cluster being nominally 4 KB). Until these clusters are over-written by another file or process the data are recoverable in part or whole. Thus “deleted” personal or sensitive information may be accessible to those with less than honorable intentions. There are numerous programs and services available to recover “lost” data; for example, BringBack (see http://www.toolsthatwork.com/bringback.htm), Recuva (see http://www.piriform.com/recuva), R-Studio (see http://www.data-recovery-software.net/), Ontrack Data Recovery (see http://www.ontrackdatarecovery.com/), Data Recovery Services (see http://www.datarecovery.net/), and ABC Data Recovery (see http://www.abcdatarecovered.com/)3. Of course these tools and services can also be used by individuals seeking to acquire personal information for nefarious purposes. Baring completely overwriting a disk drive [for example Darik’s Boot and Nuke, see http://www.dban.org/; Shredit, see http://www.mireth.com/pub/siwe.html; and cyberCide Data Destruction, see http://www.cyberscrub.com/en/]—and/or physically destroying the drive—how can a user be reasonably assured that sensitive information has been truly deleted? Below are listed 11 programs that offer secure “cleansing” of deleted files.
