Mastering Reverse Engineering

Identification and Extraction of Hidden Components

Today, the most common use for reverse engineering is in targeting malware. Like any other software, malware has its installation process. The difference is that it does not ask for the user's permission to install. Malware does not even install in the Program files folder where other legitimate applications are installed. Rather, it tends to install its malware file in folders that are not commonly entered by the user, making it hidden from being noticed. However, some malware shows up noticed and generates copies of itself in almost all noticeable folders such as the desktop. Its purpose is to get its copies executed by users, be it by accidental double-click or by curiosity. This is what we usually call malware persistence.

Persistence is when malware consistently runs in the background. In this chapter, we will be pointing...

Technical requirements

The operating system environment

Doing reverse engineering requires the analyst to understand where the software being reversed is being run. The major parts that software requires in order to work in an operating system are the memory and the filesystem. In Windows operating systems, besides the memory and the filesystem, Microsoft introduced the registry system, which is actually stored in protected files called registry hives.

The filesystem

The filesystem is where data is stored directly to the physical disk drive. These filesystems manage how files and directories are stored in the disk. Various disk filesystems have their own variation of efficiently reading and writing data. 

There are different disk filesystems...

Typical malware behavior

Malware is simply defined as malicious software. You'd expect bad things to happen to your system environment once malware has entered. Once typical malware enters the system, it does two basic things: installs itself and does its evil work. With the intent of forcing itself to be installed in the system malware does not need to notify the user at all. Instead, it directly makes changes to the system.  

Persistence

One of the changes malware makes in the system is to make itself resident.  Malware persistence means that the malware will still be running in background and, as much as possible, all the time. For example, malware gets executed after every boot-up of the system...

Tools

Identifying the registry entry, files dropped, and running processes that are related to the malware requires tools. There are existing tools that we can use to extract these objects. There are two analysis events we should consider: analysis after the malware has been executed and analysis before the malware executes. Since our aim for this chapter is to extract components, we will discuss the tools that can help us find suspected files. Analysis tools that are used after we have extracted our suspected malware will be discussed in further chapters.

When a system has already been compromised, the analyst would need to use tools that can identify suspected files. Each suspected file will be analysed further. To start off, we can identify it based on persistence.

  1. List down all processes and their respective file information
  2. From the list of known registry persistence paths...

Summary

In the first chapter, we learned about reverse engineering and its importance when analyzing malware. To begin with our reverse engineering adventures, we have to learn the system we are analyzing. We discussed the three main areas in the Windows operating system environment: memory, disk, and the registry.  In this chapter, we aimed to find malware from a compromised Windows system by extracting suspected files. To do that, we listed common startup areas in the system that we can search into. These areas include the registry, task schedules, and startup folder.  

We learned that typical malware behaves by installing itself and runnng code that harms the system. Malware installs itself basically for persistence which results in the malware file triggering most of the time the system is online. We then listed a few behaviors as to why malware was called malicious...

Description

If you want to analyze software in order to exploit its weaknesses and strengthen its defenses, then you should explore reverse engineering. Reverse Engineering is a hackerfriendly tool used to expose security flaws and questionable privacy practices.In this book, you will learn how to analyse software even without having access to its source code or design documents. You will start off by learning the low-level language used to communicate with the computer and then move on to covering reverse engineering techniques. Next, you will explore analysis techniques using real-world tools such as IDA Pro and x86dbg. As you progress through the chapters, you will walk through use cases encountered in reverse engineering, such as encryption and compression, used to obfuscate code, and how to to identify and overcome anti-debugging and anti-analysis tricks. Lastly, you will learn how to analyse other types of files that contain code. By the end of this book, you will have the confidence to perform reverse engineering.

Who is this book for?

If you are a security engineer or analyst or a system programmer and want to use reverse engineering to improve your software and hardware, this is the book for you. You will also find this book useful if you are a developer who wants to explore and learn reverse engineering. Having some programming/shell scripting knowledge is an added advantage.

Contained the information necessary to go from casual malware analyst to occasional hero. The crux of the matter is developed when the author hits on key points necessary to repackage executables while coding out the malicious logic -- especially logic intended to ruin early-stage and mid-stage analysis efforts that are focused by the adversary towards the amateur reverser. Other books in this vein do not necessarily cover the the necessary steps to champion repatching. In the future, a serious book might cover more advanced topics, such as hot patching, but I think this book covers most of the subject matter well.The book may not have a lot for an average exploit developer, or for reversers who are not subject to the cat-and mouse game of anti-debugging, anti-tampering, anti-emulation, and vm-detection techniques. For those who want to up their skills and abilities in critical areas that key cybersecurity countermeasures such as FireEye, Palo Alto Networks, McAfee ATD, and Microsoft ATP/Defender might miss -- this is the right book at the right time. This book also has the ability to foresee malware intelligence as a future decisive area where cybersecurity decisions are made. You have to read into it a little bit. It's not obvious, so maybe give it a few reads, embellish the ideas and concepts by practicing them, and spend a little effort beyond what the book provides.You will find no better modern resource on the in-the weeds methods (not just the tools, but the techniques!) of malicious logic reversing. If you intend to do battle with a disassembler, debugger, or other related weapon of choice -- look no further than this written material on this topic.

TLDR:The title is misleading. This book is an excellent primer for Malware Analysis and I highly recommend it if you're new to it. However, expect to quickly move onto other books/resources once you need any sort of depth into any of the tools/techniques.Summary:The title makes it seem like a more in-depth book for people already familiar with the basics of reverse engineering and thus are looking for new techniques or ways to improve their existing skillsets. Instead, this book is an introductory book into Malware Analysis. If it's treated like that, I do recommend this book for anyone wanting a good primer into Malware analysis. I understand that there's a lot to cover (Ex: static analysis have entire textbooks dedicated to them) so don't expect an in-depth guide on the tools/techniques.Pros:- Touches on a good number of techniques and tools used for Malware Analysis. There were a couple the author mentioned that I was not yet aware of.- Touches on a good number of topics such as anti-debugging / anti-vm / metamorphism- Pretty easy to follow and not overly bloated. Gives enough information that one would be able to look up areas they aren't familiar with and expand their knowledge.- Explanations were easy to follow.Cons:- The title is misleading. This is really the biggest con. It really should be called "A Primer on Malware Analysis".- This book is far from comprehensive. If you were looking for a comprehensive textbook on Malware Analysis with an appropriate amount of exercises, this isn't the book for you. This is less of a con if you approach this book as a primer.- It's $45 on Amazon. I read mine thru Packt Publishing's site since I have an account there, but $45 is way too steep a price for this book. I feel it's worth more like $25, $30 at most. The only way I would justify $45 is if it had more exercises.

This would be the worst book I've read about reversing if it was about... reversing. Instead it is very brief peek into several available tools that aid in malware analysis. The chapter about MBR reversing with bochs is worst than one provided by IDA Pro authors available at Hex Blog site for free. IDA capabilities are not even scratched, all the code is targeting x86 32 bit platforms (with brief exception of tips how to run ARM base linux distro in QEMU). The book doesn't even explain how disassembler works hence the chapter about code obfuscation are a bit useless, especially considering the fact that there are very few examples being discussed. Anti debugging and anti emulation tricks are also very briefly discussed. x64 architecture is not discussed, just like ARM (with single exception above). Don't buy this book, there are many others great publication on this topic available today.

Der Text wird richtig gezeigt: es kann problemlos vergrößert werden aber die Bilder bleiben leider extrem klein: es ist schwer zu erkenne, was sie zeigen sollten.Das zweite Bild zeigt das Hauptfenster von Ollidbg: Ich habe es erkannt, nur weil Ich es regelmäßig benutze.Dazu, die Quelltexte werden mit einer Schriftart gezeigt, die extrem dünn ist, praktisch unleserlich (drittes Bild).Man fragt sich, warum solche Probleme niemandem aufgefallen sind.Komisch ist auch, dass „Blick ins Buch“ eine mackellose Darstellung der Seiten zeigt, auch derjenigen, die bei Kindle Windows die Darstellungsprobleme zeigen, die Ich beschrieben habe.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
