Disk-based analysis is the cornerstone of cyber forensics, whether it be to track what a suspect was doing or simply to recover accidentally deleted files. This lab introduces students to the process of imaging and forensically analyzing disks, including finding artifacts such as deleted files. The free Autopsy® forensic browser will be used in addition to command-line programs from the open-source Sleuth Kit® tool set.
Prerequisites
In order to get the most out of this lab, you should be comfortable with cyber forensics best practices (chain of evidence, etc.) and be comfortable with a Linux/Unix command line.
Expected Duration

GRR Rapid Response is an open source live forensics tool originally created by Google. GRR allows an investigator to collect data about running systems on a network, anywhere from one system to thousands. In this lab, students will perform live remote forensic investigations against running systems. Without having to take the systems offline for imaging, students will examine running processes and network connections, files and disk artifacts, and registry keys across multiple target machines in a forensically-sound manner.
Prerequisites
You should have a basic familiarity with computer forensics processes and tools in order to get the most out of this lab.

Introduces students to the process of investigating usage of peer-to-peer (P2P) file sharing services for trading illicit content. Students learn what artifacts of P2P file sharing usage are left on a suspect’s hard drive, as well as how to extract forensically-relevant information from the raw data. Students then use Architecture Technology Corporation’s P2P Marshal™ software in a hands-on practical, gathering evidence from provided forensic disk images using Microsoft Windows®.
A copy of the P2P Marshal software is available free of charge to anyone enrolled in this course.
Prerequisites
Basic cyber forensics knowledge and best practices are recommended.

Analyzing a suspect system “live”, before disconnecting it and imaging the disks, often yields valuable forensic evidence. Further, it can help you determine whether a crime has been committed at all, or whether the system contains evidence at all, thereby avoiding time-consuming examination of irrelevant machines. The Volatility® framework is the dominant open-source memory analysis framework, examining RAM snapshots from a large variety of operating systems in multiple formats. This lab introduces students to the process of capturing a live RAM image and analyzing it using Volatility. Students will learn about several Volatility plugins for analyzing a Windows memory image, then analyze actual RAM images, including one with active malware, and view the results.
Prerequisites
In order to get the most out of this lab, you should be familiar with cyber forensics best practices (chain of evidence, etc.) and be comfortable with a Linux/Unix command line.
This lab does not directly discuss the process of acquiring a RAM image. There are several free tools available on-line for this purpose.

Analyzing a suspect system “live”, before disconnecting it and imaging the disks, often yields valuable forensic evidence. Further, it can help you determine whether a crime has been committed at all, or whether the system contains evidence at all, thereby avoiding time-consuming examination of irrelevant machines. Rekall is an advanced, open-source memory capture and analysis framework that has expanded to include a variety of live incident response tools. This lab introduces students to the Rekall framework, both for extracting evidence from memory images and for analyzing the current live state of the system. Students will learn about several Rekall tools, both on the command line and via the interactive console, for analyzing memory images. Students will then analyze several images of Windows systems with in-memory malware.
Prerequisites
In order to get the most out of this lab, you should be familiar with cyber forensics best practices (chain of evidence, etc.) and be comfortable with a Linux/Unix command line. An understanding of operating systems concepts, such as processes and network connections, is also required.
While this lab makes use of Rekall's "live" mode, which generates a virtual RAM image on the fly, this lab does not directly discuss the process of acquiring a RAM image. There are several free tools available on-line for this purpose.

A security analyst will likely be asked some time in his or her career to conduct a forensic analysis of a Windows workstation or server. In this lab the student will learn about forensic artifacts commonly found on Windows computers. Forensic artifacts are traces of user activity left behind on a computer even after the user logs out or the computer is shut down.
In this lab, students will investigate a suspected data breach by an employee of an organization. They will be given a disk image of the employee's Windows workstation. They will learn where to look for forensic artifacts and the use of tools such as Autopsy®, Registry Editor, RegRipper, LECmd, JumpList Explorer, RecentFileCacheParser, PECmd, and ShellBags Explorer to extract information from these artifacts.
Prerequisites
Basic cyber forensics knowledge and best practices are recommended, as is familiarity with the Windows command prompt.
