Table of Contents

Description

Windows forensics is an essential skill in the cybersecurity world. This course covers a broad spectrum of aspects of the forensic investigation process performed on Windows OS. Participants will learn how different computer components work and how to investigate after a cyber-incident. The training will focus on developing hands-on capabilities of forensics teams or individual practitioners in these areas:

  • Searching the hard drive for evidence
  • Processing hidden files that are invisible or inaccessible containing past-usage information
  • Performing a forensic analysis on a computer to reveal usage details, recover data, and accomplish a full inspection after the machine has been defragged or formatted

How to make the most of this course?

In order to succeed in the course, the following requirements must be met:

  • Participation in all practical laboratories
  • Self-work at home between lessons
  • Repetition of materials, self-learning, performing tasks, etc…

In addition to regular classroom studies, the participant is required to practice at least 10 hours a week in order to gain practical experience in the field.

Real Cases Studies

Case Study #1 (WF001)
A small finance company named Bitsafe has suffered from a collision attack. The incidents caused the loss of $130,000, by exploiting and forging the digital signature of a transaction between clients, allowing the attacker to break the communication encoded with the SHA-1 algorithm.
Reference
Case Study #2 (WF002)
Cellebrite, a company that provides digital forensics tools and software, was hacked. The hacker managed to extract 100 GB of photos containing law enforcement investigations evidence. The hacker has not yet publicly released anything from the stolen data archive, which includes customers' information, databases, and other technical data.
