Reverse engineering is the process of analyzing and modifying software without having access to its source code. It can be used for various purposes such as understanding how a program functions, finding vulnerabilities or bugs, removing limitations or restrictions, enhancing features or performance, creating new versions or variants, etc.
Reverse engineering is not only useful but also fun and challenging. It requires a combination of technical skills, creativity and curiosity. It can also open up many opportunities and possibilities for personal or professional development.
However, reverse engineering is not easy. It can be daunting and frustrating for beginners who don't know where to start or what to do. That's why you need a good guide that can teach you the basics of reverse engineering in an easy and fun way.
One of the best guides available online is Lenas Reversing for Newbies. It is a collection of 40 tutorials that cover various topics and techniques in reverse engineering. Each tutorial comes with a video, a text file and a sample program to practice on. The tutorials are divided into four levels: basic, intermediate, advanced and expert.
In this article, we will give you an overview of Lenas Reversing for Newbies and show you how to use it to learn reverse engineering. We will also highlight some of the benefits of learning from this guide.
Lenas Reversing for Newbies: An Overview
Lenas Reversing for Newbies was created by Lena151, a female reverse engineer who wanted to share her knowledge and passion with others. She started making these tutorials in 2007 and uploaded them on her website (which is no longer active). Since then, her tutorials have been downloaded by thousands of people around the world who want to learn reverse engineering.
The tutorials are designed for beginners who have little or no background in reverse engineering or programming. They start from the very basics such as installing tools, understanding assembly language, patching programs, etc. They gradually progress to more complex topics such as encryption/decryption, self-modifying code, polymorphism, obfuscation, etc.
The tutorials are organized into four levels:
Basic: This level consists of 10 tutorials that introduce you to the essential tools and concepts of reverse engineering. You will learn how to use OllyDbg (a popular debugger), PEiD (a program identifier), LordPE (a hex editor), SmartCheck (a Visual Basic decompiler) and DeDe (a Delphi decompiler). You will also learn how to patch programs (modify their code), remove nags (annoying messages), bypass checks (such as serial number verification), etc.
Intermediate: This level consists of 10 tutorials that teach you more advanced techniques and methods of reverse engineering. You will learn how to use API's (application programming interfaces), inline patching (modifying code within a function), diversion code (redirecting code execution), keygenning (generating valid serial numbers), etc.
Advanced: This level consists of 10 tutorials that deal with some of the most challenging aspects of reverse engineering. You will learn how to handle packers and protectors (tools that compress or encrypt programs), imports rebuilding (restoring missing functions), API redirection (changing function calls), stolen bytes (replacing code with jumps), etc.
Expert: This level consists of 10 tutorials that show you how to tackle some of the most difficult programs and scenarios in reverse engineering. You will learn how to deal with debugger detection (techniques that prevent debugging), anti-anti-debugging (techniques that bypass debugger detection), unpacking (extracting original code from packed programs), polymorphic code (code that changes itself), obfuscation (code hiding) and algorithm hiding (logic hiding).
The tutorials are very detailed and clear. They explain each step with screenshots, comments and tips. They also provide some background information on each topic and some references for further reading. They also challenge you to apply what you learned by giving you some exercises or tasks at the end of each tutorial.
How to Use Lenas Reversing for Newbies
If you want to use Lenas Reversing for Newbies to learn reverse engineering, here are some steps you need to follow:
Download the tutorials: You can download all the 40 tutorials from the official website or other sources such as this blog . The download size is about 500 MB. The files are in ZIP format so you need to extract them using a tool such as WinRAR or 7-Zip.
Install the required tools: You need some tools to follow along with the tutorials. The most important tool is OllyDbg which is a debugger that allows you to analyze and modify programs. You can download it from its official website. You also need some other tools such as PEiD which identifies programs by their signatures; LordPE which edits program headers; SmartCheck which decompiles Visual Basic programs; DeDe which decompiles Delphi programs; HIEW which edits binary files; etc. You can find these tools online or in some of the tutorial folders.
Follow the instructions in each tutorial: Each tutorial comes with three files: a video file (.swf), a text file (.txt) and a sample program (.exe). You need a Flash player such Continuing the article: as Adobe Flash Player or Ruffle to play the video files. You can also use a tool such as SWF Decompiler to convert the video files to other formats such as MP4 or AVI. You can use any text editor such as Notepad or Notepad++ to read the text files. You can use OllyDbg or any other debugger to open and run the sample programs.
Try to understand the logic behind each step: Don't just blindly follow the instructions in each tutorial. Try to understand why each step is done and what effect it has on the program. Use the comments and tips provided in the text files and the videos to help you. You can also use online resources such as this article to learn more about reverse engineering methods and principles.
Experiment with different programs and scenarios: Don't limit yourself to the sample programs provided in each tutorial. Try to find other programs that you can reverse engineer using the same techniques. You can use tools such as PEiD or GitHub to find programs that are suitable for reverse engineering. You can also try to modify the sample programs in different ways and see what happens. For example, you can change some strings, numbers, colors, images, etc.
Challenge yourself to find new solutions: Don't settle for the solutions given in each tutorial. Try to find alternative or better solutions that achieve the same goal. For example, you can try to patch a program with fewer bytes, use a different plugin or tool, find a different way to bypass a check, etc. You can also try to solve some of the exercises or tasks given at the end of each tutorial.
