Ad-hoc File System Forensics Load image into analysis software. ▫ Analyze! Image: Hewlett Packard .. see Brian Carrier: „File System Forensic Analysis“. Request PDF on ResearchGate | File System Forensic Analysis | The Definitive Guide to File System Analysis: Key Concepts and Hands-on TechniquesMost. PDF | Digital forensics is the identification, extraction, analysis and documentation of digital evidence from storage media. It is relatively new technology which is.
I would open up an Open source tool X, because there is usually a detailed documented process that would make it easier for me as an investigator to explain how I acquired the related information.
Moreover, I would also be able to explain the various tools and techniques I used which in turn helps with the integrity and helps back up my statements, especially for court purposes. Based on the Request for Analysis pdf document, come up with five keywords that would be good to search for in this investigation.
Please provide a justification for each choice. Barzini-This is the name of the crime Family that Mr. Lawless was believed to be working with. Emilio-This is the first name of the head of the crime family Mr. Lawless was working with.
New Jersey- This is the location that the family is based out of. This could potentially lead to clues for crime activity. Research and provide an overview of the Locard Exchange Principle. How is this principle relevant to digital forensics analysis? According to Marilyn T. This principle is of significant importance to digital forensics because individuals always seem to leave some type of trace of where they have been in the digital world.
What is a raw image? From data acquisition point of view, raw images are easier to manage. A raw image is the most purist image possible. RAW or DD images just contain the data from the original source, and nothing else. Any hash data etc is usually stored in a separate log file that is generally stored with the image file. You have the image at the best state possible.
RAW files will allow a forensic specialist to adjust the image to obtain the best possible representation of that scene or evidence image for analysis. Find a file of interest to this investigation from the image drive by exploring the image in Autopsy and explain why you believe the file is of interest in the investigation.
The following file might be of interest for the investigator as it relates to this investigation. Though the file does not directly link the two individuals of interest, it does produce evidence that Mr.
Lawless did research utilization of Cyber Technology for extortion tenacities. Under this file I am able to see what Joey did while using this laptop.
I can search his cookies to see where he frequented on the internet, I can check his documents that he may have been working on, as well as his most recent history. Find a deleted file of interest to this investigation from the image drive by exploring the image in Autopsy and explain why you think the file is of interest in the investigation.
The following deleted Outlook files can be utilized to analyze the type of communication between Mr.
Laweless and Mr. The deleted file below shows Mr.
Lawless researching activity of two IP addresses, The emails are carefully crafted to ensure the anonymity of the sender and receiver. There are more to the e-mail traffic I just did not wanted to use too many screen shots.
The email goes on to say " Once I have that I can begin scanning the inside to entrench myself further. I usually look for large sheep that have a high value and are often easier to get out of the fence line since that have a public facing presence".
What type of file system was the forensic image evidence collected from? The file system type that was selected for this forensic image was New Technology File System NTFS as stated on part 19 of the lab instructions as well as under the file system details page.
What is this useful for? Investigators should take notes during an investigation because it helps them remember when they find useful information that can help with an investigation. Carrier begins with an overview of investigation and computer foundations and then gives an authoritative, comprehensive, and illustrated overview of contemporary volume and file systems: Crucial information for discovering hidden evidence, recovering deleted data, and validating your tools.
Along the way, he describes data structures, analyzes example disk images, provides advanced investigation scenarios, and uses today's most valuable open source file system analysis tools—including tools he personally developed. Coverage includes. When it comes to file system analysis, no other book offers this much detail or expertise.
Whether you're a digital forensics specialist, incident response team member, law enforcement officer, corporate security specialist, or auditor, this book will become an indispensable resource for forensic investigations, no matter what analysis tools you use. He has authored several peer-reviewed conference and journal papers and has created publicly available testing images for forensic tools.
There already exists digital forensic books that are breadth-based and give you a good overview of the field and the basic concepts.
This book complements those books and gives you more details of file and volume systems. I started this book because there was a large void with respect to documents and books describing file systems.
While developing The Sleuth Kit , I frequently had to use source code and trial and error to determine how the data were laid out. The lack of public documents made it difficult to explain, for example, why file recovery is not the same for all file systems and that each NTFS file has at least three sets of timestamps.
It also makes it difficult for an investigator to testify how her analysis tool works and where it found the evidence. There are two target audiences for this book.
