Anti-Analysis: Analyzing Smokeloader
In this lab, you'll practice reverse engineering and defeating anti-analysis techniques in low-level languages (C / ASM). When you're finished with this lab, you'll have an understanding for how malware mangles, manipulates, and prevents disassembly and debugging through certain techniques. You'll also identify what these techniques look like through reverse engineering and how to remove/patch them to complete your analysis.

Challenge
Initial Extraction (Stage 1)
SmokeLoader is a advanced sample that contains several embedded payloads. Our goal for this first challenge is to identify the first stage of shellcode and extract it.
-
Challenge
Stage 2
This challenge will focus on debugging the extracted shellcode from Stage1 and extracting the heavily obfuscated Stage2 shellcode stub. This version of SmokeLoader contains two different shellcode stubs that perform the decryption and loading of Stage2 into memory.
-
Challenge
Final Stage
We will focus on the final two stages of SmokeLoader in this challenge. The heavily obfuscated Stage2 shellcode with opaque predicates, encrypted functions and anti-debugging techniques. Then, we will be extracting the final Stage3 shellcode and extracting its RC4 encrypted configuration.

The Last Challenge
Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that flittered into existence just for you.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
Learn by doing
Engage hands-on with the tools and technologies you’re learning. You pick the skill, we provide the credentials and environment.
Follow your guide
All labs have detailed instructions and objectives, guiding you through the learning process and ensuring you understand every step.
Turn time into mastery
On average, you retain 75% more of your learning if you take time to practice. Hands-on labs set you up for success to make those skills stick.
