Overview of the Investigation

Title: Clowning About Again

In the state of Western Australia, it is illegal to access, own or distribute digital content relating to clowns. An allegation was been made to law enforcement whereby a witness claims to have seen an individual access clown related content within a place of work. Following the approval of formal warrants, the computer in question was seized from the work place. The computer was then forensically acquired using FTK Imager. Unfortunately, the junior investigator who obtained the ‘forensic image’ of the computer only performed a logical acquisition. To worsen the situation, the junior investigator forensically wiped the original hard drive from the computer. Fortunately, the logical acquisition was undertaken in a forensically sound manner. The suspect, Clark denies accessing clown content. However, Clark does confirm that the computer does belong to him. Clark stated that he does not always take the computer home or lock it when he is away from his desk.

You are a consultant who specialises in digital forensic investigations. You have been assigned the task of examining a ‘forensic’ image of the laptop, which was seized with correct warrants. It is currently unknown what Clark was doing with the clown content. In Clark’s opinion, the computer was infected with malware which resulted in any potential content appearing on the computer.

Your task is to investigate the supplied forensic image using appropriate tools and process and to develop and prepare a written report on your findings. You may use any tools to undertake the investigation but you must justify all of your actions!

Your report must follow the report structure shown below.

A detailed representation of all content identified, extracted and analysed in the investigation. All evidence must characterised, explained and examined. What is the value of the evidence to the investigation? What does each piece of evidence mean? Does evidence support or negate the allegations made?

Detail all information relating to possible use/ownership of the evidence identified and extracted. How can you link the evidence to a particular owner? Is there any digital evidence, which demonstrates ownership of the device or content?

Was the digital content purposefully accessed/used/downloaded/installed? Was it accidental? Was it a third party? Was it malicious software? Present all evidence to support your theory.

How many files of every type were present on the system? What percentage of these files relate to the offence? What does this mean for the overall investigation?

What applications are installed that relate to the investigation? What purpose do these applications serve? Have they been used/run? Dates/times the application was used. What impact do these applications have on the investigation?

Overview of the Investigation

Primary focus of this project is explore the progressed computerized legal sciences images by using reasonable tool. Basically, region of Western Australia does not offer access to modernized substance related to comedians since it is unlawful access, guarantee and circle the propelled substance related to jokesters. The comedians' automated substance are gotten to by malware. Thusly, this examination is prerequisites to look into the propelled substance related to the jokesters. Generally, the charge was make the law approval where by an eyewitness maintains to get to the jokesters related data inside a work put. In any case, some entertainer's substance are gotten to without the work put. Unfortunately, junior propelled operator got the advanced crime scene investigation image of the PC that is comedians substance played out an authentic anchoring. Along these lines, this condition the junior computerized criminology inspector wiped the primary hard drive from the PC. Since, the reliable anchoring is done by forensically strong way. Thusly, the lesser pro easily chose the legitimate picture. The suspect, Clark demies the getting to the entertainer content and moreover Clark does not attest that the PC has a place with him. The Clark says, he doesn't by and large take the PC home or jolt it. Thusly, senior analyst needs to assess the legitimate image of the lap which was seized with right warrants. Furthermore, also Clark express the PC was polluted with malware that achieved different potential substance appearing on the PC. This examination is done by using the autopsy forensics tool. The examination will be done and discussed in detail.

Here, client needs to give the presentation of substance relating to the offense. The gave logical examination communicated that the charge was make the law prerequisite where by an eyewitness pronounces to get to the comics related data inside a work put. Nevertheless, a few comedians substance are gotten to without the work put. Shockingly, junior analyst obtained the criminology image of the PC that is comedians substance played out a real anchoring. Thusly, this situation the junior automated criminology analyst wiped the main hard drive from the PC. Since, the intelligible acquiring is done by forensically stable way. Thusly, the junior analyst easily chose the criminological picture. Thusly, senior analyst needs to examine the quantifiable image of the lap which was seized with right warrants. This examination is done by using the autopsy forensics tool.

Tools and Process Used in the Investigation

Here, user needs to using the 7 zip extraction to open the all the provided case image and it converted into the single case file. To extract the provided case file by using the below steps. Fisrt, user needs to download and install the 7 zip software.After, open 7 zip and also open the provided case file. It is illustrated as below.

Once files are upload successfullly on the 7 zip, after right click the case file to clck the 7 zip to choose the extract to compressing the provided the case file into single case file. The compressing process is demostrated as below (Boddington, 2016).

After, all the case file are compresed into case file.7z. But, provided case file does not converted into single image otherwise it converted into one folder.Then, user requires to download and install the autopsy tool. The installation of autopsy tool is finished, after open the autopsy tool to click the new case.  After, user enter the case information and save the case file to browser the directory. It is demonstrated as below. Here, case name as digital forensics. Then, click the next button (Computer forensics, 2010). Then, enter the case number is digital forensics case 01. After, proceed the analysis by click the next button. Once new case created, after add the provided case file to choose the unallocated disk image then click the next button. Then, browse the forensics image folder to choose the appropriate folder and click the forensic image which is 182.7z.002. Then, click the next button. After, configure the forensic image to ingest modules and click the next button.  Finally, added the data source for created case by click the Finish button. Successfully data source is added into the case. Similarly, add the all the forensics images on the created case. The provided all the forensics image is successfully added to the digital forensics case.

Once, data sources are added into the created case after user needs to identify the evidence for digital forensics investigation. A detailed representation of all content identified, extracted and analysed in the investigation are discussed in below issues.

This issue is used to identify the information about the provided case file.
