...Assignment 4 Computer Forensic Tools Derek Jackson Computer Crime Investigation Professor: Dr. Jessica Chisholm 03/06/2016 When purchasing computer forensics tools and resources for a company, you always want to make sure you are doing the necessary research and determining which of these programs are the best options for the company. This is very important job in any company as you are in charge of not only protecting the company’s data with these tools, but also recovering any information that may have been lost or deleted. There are many programs that are available that can be used to recover deleted files. Two of the programs that you could use are the MiniTool Partition Recovery and PC Inspector File Recovery. The MiniTool Partition Recovery is a free program that has a wizard-based interface which makes it very easy and straightforward to use and understand. You can point the MiniTool Partition Recovery at the problem drive, specify the area to be searched, and it will scan for the missing partition. Then a report will generate that will let you know what the program has found, and you can then recover that partition in a few seconds typically. The only downfall is that you won’t get a bootable recovery disk, so if the partition is damaged then the MiniTool Recovery program won’t be able to recover the deleted partition. The PC Inspector File Recovery allows you to be able to recover a full set of missing files on both FAT and NTFS drives. They are clearly...

...growing danger from crimes committed against computers, or against information on computers, is beginning to claim attention in the India. The digital age has dramatically changed the scope of a crime by adding the electronic component and it comes a new form of science ≴Computer Forensic Science≵. Computer Forensic allows for the evidence of cyber crime to be admissible in court when prosecuting the cyber criminal. In most countries, existing laws are likely to be unenforceable against such crime. Cyber laws, as it stand today, gives rise to both positive & negative consequences. The main negative consequences is the digital soup so vague that many refer to it as the dark sides of technology and that cyber criminal currently have upper hand. The applicability and effectiveness of our existing laws need to be constantly reviewed to face the risk coming from the cyber world. In this paper we are going to firstly describe the computer forensic, cyber crimes, cyber laws of nation & technology challenges. Aim of this paper is to act as a catalyst to raise awareness regarding computer forensic which continues to grow as one of the most important branch of science and help in investigation of cyber crime which continues to grow as one of the most potent threats to the Internet and computer users of the cyber society of 21st century in India Introduction The rapid change occurring in the present era of Information Technology and the computer has gained popularity in every aspect of...

...Computer Forensics I (FOR 240-81A) Project #3 Case Background The Suni Munshani v. Signal Lake Venture Fund II, LP, et al suit is about email tampering, perjury, and fraud. On December 18, 2000, Suni Munshani (Plaintiff) filed a suit against Signal Lake Venture Fund. Mr. Munshani claimed that he was entitled to warrants in excess of $25 million dollars from Signal Lake. In February 2001, Signal Lake Venture Fund II, LP, et al. (Defendant) became privy to the court filings in this case. Within the filings there was an email provided by Mr. Munshani from Hemant Trivedi, CEO of one of the portfolio companies, stating he was indeed entitled to the warrants. Mr. Trivedi denied any knowledge of the email, or any such communication with Mr. Munshani. In an effort to prove their innocence, Signal Lake hired a computer forensic group to conduct a private investigation. The investigation did not show any evidence of the supposed email provided to the court by Mr. Munshani. Mr. Trivedi filed an affidavit stating that the email was forged, while Mr. Munshani filed an affidavit stating the email was real. In March 2001, a computer forensics expert, Kenneth R. Shear, was appointed by the court to perform a forensic examination on the questioned message (the message provided by Mr. Munshani) and the comparative message (a second message from Mr. Trivedi found on Mr. Munshani’s computer). Mr. Shear worked for a company called Electronic Evidence Discovery, Inc. (EED). Mr. Shear’s forensic...

...International Journal of Digital Evidence Fall 2007, Volume 6, Issue 2 Computer Forensic Analysis in a Virtual Environment Derek Bem Ewa Huebner University of Western Sydney, Australia Abstract In this paper we discuss the potential role of virtual environments in the analysis phase of computer forensics investigations. General concepts of virtual environments and software tools are presented and discussed. Further we identify the limitations of virtual environments leading to the conclusion that this method can not be considered to be a replacement for conventional techniques of computer evidence collection and analysis. We propose a new approach where two environments, conventional and virtual, are used independently. Further we demonstrate that this approach can considerably shorten the time of the computer forensics investigation analysis phase and it also allows for better utilisation of less qualified personnel. Keywords: Computer Forensics, Virtual Machine, computer evidence. Introduction In this paper we examine the application of the VMWare (VMWare, 2007) virtual environment in the analysis phase of a computer forensics investigation. We show that the environment created by VMWare differs considerably from the original computer system, and because of that VMWare by itself is very unlikely to produce court admissible evidence. We propose a new approach when two environments, conventional and virtual, are used concurrently and independently. After the images...

...Digital Forensics is an important aspect to computer systems security. I mean we are talking about Identifying, Collecting, Preserving, Analyzing, and Presenting evidence digitally. Therefore, preserving electronic evidence is important. Investigating Data Theft is a malice act towards a company/ organization (Kruse, 2001). Such theft is made by an employee that is either terminated or resigning. Motives for data theft include setting up a competing business, using the information at a new job, sense of ownership of what was created, and revenge against the employer, among other things. Common Theft include, customer information, financial records, software code, email lists, strategic plans, process documents, secret formulas, databases, research and development materials, and employee records. Now, with such theft around, we often wonder how is such theft achieved. Knowing how technology is always advancing each year, the millennium era grows with fascinating knowledge on the know how to working a computer, hard drives, etc. Tools like flash drive, which can hold thousands of documents that can be copied to the flash drive, and taken anywhere. Then you have Dropbox, remote desktop connections, personal email accounts, smart phones, CD’s/DVD’s, and FTP ( File Transfer Protocol ) (Kruse, 2001) There is always this saying, that personnel who steal data often leave a trail of digital evidence that proves invaluable when investigating data theft.

...Computer Forensics The world of crime has expanded right along with the explosion of the internet. The modern cyber criminal has veritable global playground in which to steal money and information from unsuspecting victims. Computer forensics is a quickly emerging science against the increasingly difficult battle to bring criminals to justice who perpetrates crimes on others. The computer forensics field is a relatively new investigative tool but enjoys continual advances in procedures, standards, and methodology which is making the identification, preservation, and analyzing of digital evidence a powerful law enforcement apparatus. The job of the cyber forensic professional is to look for clues the attacker left behind on web sites, servers, and even the e-mail message itself that will unravel their sometimes carefully woven veil of secrecy. Attackers come in all forms and from a variety of different circumstances. For instance, an attacker can begin a phishing scam with only a web server they control with very little programming experience and a way to send a lot of e-mail messages. (Jones 4) In order to combat the waves of cyber-attackers, we must utilize Open Source Community applications to combat the continual onslaught of infections, exploitations, and trickery employed everyday against our systems and networks. Today's attacker uses a variety of technologies to employ their methods and understanding those abilities is integral to preparing for an investigation...

...Assignment 1: Computer Forensics Overview CIS 417 Computer Forensics Computer forensics is the process of investigating and analyzing techniques to gather and preserve information and evidence from a particular computing device in a way it can be presented in a court of law. The main role of computer analyst is to recover data including photos, files/documents, and e-mails from computer storage devices that were deleted, damaged and otherwise manipulated. The forensics expert’s work on cases involving crimes associated with internet based concerns and the investigations of other potential possibilities on other computer systems that may have been related or involved in the crime to find enough evidence of illegal activities. Computer experts can also use their professional knowledge to protect corporate computers/servers from infiltration, determine how the computer was broken into, and recover lost files in the company. Processes are used to obtain this information and some of the processes are as follows; * Investigation process: Computer forensics investigations will typically be done as part of a crime that allegedly occurred. The first step of the investigation should be to verify that a crime took place. Understand what occurred of the incident, assess the case, and see if the crime leads back to the individual. * System Description: Next step, once you verified the crime did occur, you then begin gathering as much information and data about the specific...

...responders need to recognize is that the computer was on when the suspect was arrested and there may be evidence that they need to collect right away. If data of apparent evidentiary value is in plain view onscreen. The first responder should seek out personnel who have experience and training in capturing and preserving volatile data before proceeding. First responders should also be alert to the crime scene environment. They should look out for pieces of paper with handwritten notes, passwords, usernames, and software and hardware manuals. These forms of evidence also should be documented and preserved in compliance with departmental policies. In this case the computer should also be checked for DNA so investigators can match the suspects DNA to the arson crime scenes. Also TimeFrame Analysis can be used to link any files of interest to the timeframes of the investigation. All these things can help link the suspect to the crimes, and in doing so can help tell the insurance company whether the claims are valid. 2. Case 4-4 (bomb threat) A list of what items should be included in an initial response field kit to ensure preservation if digital evidence. The initial response field kit should be lightweight and easy to transport. With this kit, you can arrive at a scene, acquire the data you need, and return to the lab as quickly as possible. * Small computer toolkit * Large-capacity drive * IDE ribbon cable * SATA cables * Forensic boot media containing an acquisition...

Forensics is the process of using scientific knowledge for collecting, analyzing, and presenting evidence to the courts. (The word forensics means “to bring to the court.”) Forensics deals primarily with the recovery and analysis of latent evidence. Latent evidence can take many forms, from fingerprints left on a window to DNA evidence recovered from blood stains to the files on a hard drive. Because computer forensics is a new discipline, there is little standardization and consistency across the courts and industry. As a result, it is not yet recognized as a formal “scientific” discipline.

...FORENSICS Forensics, by and large, is the application of science to the legal process. It is an emerging research domain in India. There are many different types of forensic sciences baring their vital presence possibly in every field of human endeavor. Of these, let us now discuss about the computational, cyber and the DNA forensics. COMPUTATIONAL FORENSICS: The development of computational methods or mathematical and software techniques to solve forensic issues is called computational forensics. These methods analyze the evidence beyond human cognitive ability. They scrutinize a large volume of data, which is at any case impossible for a human mind to figure out. In spite of this, we can’t say that these techniques alone would serve our purpose because computational forensics is a field which needs huge collaboration between recognition and reasoning abilities of humans combined with comprehension and analytic abilities of the tool or a machine, which is most of the times, a computer. Computational forensics aids us to model the uncertain. At the crime scenes, we usually get incomplete or broken evidences. These evidences are later on modeled by the computational forensic tool which gives us first clues from its largest biometric database (fingerprints, criminal histories, mug-shots, scar and tattoo, physical characteristics like height, weight, hair and eye color and aliases), which is a collection of significant information regarding the criminals, their criminal history...
