Learn advanced reverse engineering techniques, from disassembling code to analyzing malicious software.
Start LearningReverse engineering is the process of analyzing software or hardware to understand its design and functionality. For software, it involves disassembling binaries, decompiling code, and using tools like debuggers to uncover vulnerabilities or hidden features. In hardware, it examines components and circuits to identify vulnerabilities. The goal is to find security flaws, recover source code, or investigate malware.

Obfuscation techniques make it difficult to understand the original logic of code. These techniques include code packing and encryption to hide the true purpose of software.
Code injection involves inserting malicious code into the program’s execution flow, often leading to arbitrary code execution or exploiting a vulnerability.
Anti-debugging techniques make it harder to reverse engineer software by detecting the presence of debuggers and preventing the analysis of code execution.
Analyzing the behavior of malware to understand how it spreads, how it interacts with the system, and how to defend against it.
Reverse engineering helps in developing exploits by understanding the vulnerabilities in binaries and crafting a way to trigger them to gain control of a system.
IDA Pro is one of the most popular disassemblers used by reverse engineers to analyze binaries and understand how they work.
Ghidra is a powerful open-source reverse engineering tool developed by the NSA, capable of disassembling and analyzing binaries across different platforms.
OllyDbg is a popular debugger used to analyze and reverse engineer Windows executables, focusing on dynamic analysis.
Static analysis involves analyzing the binary without executing it. Disassemblers and decompilers are used to inspect the code structure and uncover hidden functionality.
Dynamic analysis involves running the binary in a controlled environment, such as a debugger or virtual machine, to observe its behavior in real-time.
Reverse shells are used in reverse engineering to establish a connection from a compromised system to an attacker's system for remote control.
Binary patching allows reverse engineers to modify the code of a binary, fix bugs, or bypass anti-debugging protections.
Cryptanalysis involves reverse engineering cryptographic algorithms to break encryption or find vulnerabilities in their implementations.
