Part 1 - We are in a situation in which one of our employees is allegedly sending inappropriate photos via email within attachments. This employee has been compressing these photos using a zip utility program. When doing a forensics analysis of the employee's hard drive, we find a file named orkty.zip, but when the file is displayed, the message indicates it is corrupt. Typically, zip files are also called archive files and may be thought of as a container, a large file folder in which to place the "real information" for later retrieval. The purpose of these zip files is to allow larger amounts to be stored inside the folder for easier transporting. Just because the file says "corrupt" when attempting to open it does not mean that the data, or the proof needed, cannot be recovered. A zip file format, which is open source, has a specific structure that is defined in a zip application note. It is quite possible to receive or find a zip file that has a simple head issue; a mistake caused by the application or the process used to create the zip file. Despite this, any inaccuracies will give us a report back saying the zip file is corrupt. Typically, this can be fixed using a zip file fix routine: Click Start, click All Programs, and click Accessories Right click HYPERLINK "http://kb.winzip.com/kb/entry/283" "_blank" Command Prompt and choose Run as administrator (Windows XP: Left click Command Prompt) HYPERLINK "http://kb.winzip.com/kb/entry/289" l "CD" "_blank" Change
Files can be created in applications in a number of standard formats. You can tell which format is being used by looking at the last part of the full file name, known as the file name extension. For example, the filename dogs.bmp has the filename extension .bmp, which tells us that this is an image file stored in bitmap format.
Good file names can provide useful cues to the content and status of a file, can uniquely identify a file and can help in classifying files.
Specialized techniques for data recovery, evidence authentication and analysis of electronic data far exceeding normal data collection and preservation
Run the file above file as an administrator by right clicking and then choosing run as administrator. Click yes if there is a UAC prompt.
When was the file created, when was it accessed, was it sent and or received and by what accounts. These aspects are important because otherwise the case that the forensic scientist is working can’t be solved.
Objective 3 – A system that can ensure the safety of data from other possible circumstances that may result to corruption and loss of data.
Someone could have possibly seen if anyone other than the suspect has been seen on her computer. If I feel to proceed further I would do an audit on the computer in question and see what day and time these files
Two weeks ago, Omega experienced a significant loss of proprietary data (estimated value $550,000.00) that was stored electronically in an Oracle database in their main office in Reston. The data was unrecoverable and backups were not being routinely maintained, so no restoration was possible. Although he has no hard evidence, Omega’s CTO believes that the loss resulted from deliberate deletion of files by a systems administrator from the

Dennis sent a floppy disk with information on a Microsoft word document to the police. This is where digital forensics comes in. They found that the owner of the file was named
For this reason, it is imperative that the information gathered is reliable and accurate to ensure the evidence collected can be utilized by the digital forensic investigator for the current case (Ingalls & Rodriguez, 2011). Additionally, cyber incidents require digital forensic investigators to interview various individuals regarding the information needed for the case. According to the National Institute of Justice (2004), interviewing the system administrator, users, and employees of an organization regarding a cyber incident would provide investigators with valuable information; for example, user accounts, email accounts, network configuration, logs, and passwords. Furthermore, for digital forensic investigators to conduct an effective interview, they must have the proper tools and training to employ the interview process. For instance, formal procedures or instructions should be developed and implemented to ensure that the investigator follows a standard during all investigations. Additionally, training should be provided to ensure that digital forensic investigators comprehend by what means to prepare, conduct, and evaluate an interview. Furthermore, resources should be made available for digital forensic investigators to accomplish their tasks; for example, recording devices and references. Also, definitions should be provided to the digital forensic investigators for
Mr. Joey I. Lawless, an alleged associate of Emilio Barzini, who is the head of the Barzini crime family, was apprehended for racketeering, money laundering, and potential cybercrimes. John Fox from the XYZ Corporation requested the performance of forensic analysis of the suspect’s imaged drive (lab1_2007-1001a.img) annotating items of value and any digital evidence regarding the alleged infractions.
I would inform the employee that I can recover the files and the employee would need to fill out a form letting me know the exact names of the files missing. The first step in data recovery is to question the client. It is important to find out what operating system the employee is using and if it was a laptop or a desktop. By asking what programs/applications the
Paladin and Helix are two of the leading open-source Digital Forensics tool suites on the market. Agencies need forensic tools like these to conduct the analysis of digital systems. The systems can contain hidden information that is vital to solving a case or recovering lost files. The tools are also good for determining the effects of malicious software. Many different agencies use both tools, and they both have amazing features. But which one is better. This paper will discuss the features of both tools and determine the best choice.
In simple terms, computer or digital forensic evidence analysis is the scientific collection of data that is either retrieved or held by a computer storage device that can be used against a criminal in a court of law. For the information to be used in court it should be collected before it is presentation; therefore, there are a number of recommendations proposed to make sure that information collected meets the intended integrity.
