Practical Windows Forensics

Overview of this book

Over the last few years, the wave of the cybercrime has risen rapidly. We have witnessed many major attacks on the governmental, military, financial, and media sectors. Tracking all these attacks and crimes requires a deep understanding of operating system operations, how to extract evident data from digital evidence, and the best usage of the digital forensic tools and techniques. Regardless of your level of experience in the field of information security in general, this book will fully introduce you to digital forensics. It will provide you with the knowledge needed to assemble different types of evidence effectively, and walk you through the various stages of the analysis process. We start by discussing the principles of the digital forensics process and move on to show you the approaches that are used to conduct analysis. We will then study various tools to perform live analysis, and go through different techniques to analyze volatile and non-volatile data.

Knowing Bro


Another tool to analyze network traffic is Bro. Bro is a very powerful tool, which is often positioned as an IDS, but the possibilities are much wider with Bro. Discussing all of them in a single chapter is almost impossible, so we will consider only some of them. One of the many advantages of Bro is the ability to use ready-made parsers different protocols.

For example, the following are some of them:

  • DHCP

  • DNS

  • FTP

  • HTTP

  • POP3

  • SMTP

  • SSH

The list of these protocols is constantly expanding.

By default, Bro applies the protocol analyzers to traffic, and it records the results in the log files that correspond to different protocols.

Bro also allows you to write your own handlers in a language called Bro. For each event that occurs during the processing of the event may be caused by its handler.

For example, consider the following simple event handler discovery file:

event file_new (f: fa_file) { 
local fname = fmt ("% s", f $ id) 
Files :: add_analyzer (f, Files :: ANALYZER_EXTRACT, [$ extract_filename...
