A site offering lessons on the fundamentals of reverse engineering, binary analysis and software security. It describes hands-on tutorials, practical examples and real-world scenarios covering binary analysis, malware research, and static and dynamic analysis.
Binary Ninja offers two free ways to try the reverse engineering tool: Binary Ninja Cloud, a browser-based tool, and Binary Ninja Free, a downloadable app for local use. Cloud supports all architectures but requires uploading binaries; Free supports x86, x86_64, ARMv7 and ARMv8/AArch64 and is for non-commercial purposes or evaluation.
Reverse Engineering challenges is a collection of reverse engineering exercises contrived by Dennis Yurichev. The challenges are organized by level, type, architecture and operating system, with levels ranging from 1 to 3. The site also offers an about page.
A beginner's guide to capture the flag (CTF) hacking competitions. It explains what a CTF is, describes jeopardy-style CTF categories such as reverse engineering, Pwn, crypto and web, and covers logistics, finding CTFs and reverse engineering resources.
ImHex supports reverse engineering, malware analysis, file inspection, or security research workflows.
LemmeDebug supports reverse engineering, malware analysis, file inspection, or security research workflows.
TweetedAt is a tool that extracts the date and time from a tweet ID by reverse-engineering Twitter Snowflake. It also offers Reverse TweetedAt, which converts a timestamp to a tweet ID prefix.
ImHex Web is a free and open source hex editor for reverse engineers, developers and data analysts. It runs directly in the web browser with the help of Emscripten and WebAssembly. A native version is also available.
CyberArsenal is a forum focused on computer and network security and reverse engineering. Content requires signing up to view and participate. The site states there is no payment, credits system, or reply-to-reveal. Sections include general discussion, requests for installer or setup files, requests related to security or reversing, and red team tools and techniques.
APK Editor Studio is a free, open-source, cross-platform APK reverse-engineering tool for Windows, macOS, and Linux. It allows users to extract, edit, or replace APK resources, including changing the app icon and title, removing unwanted permissions, signing and installing APKs, and viewing signatures. It includes many built-in tools such as a code editor, manifest editor, and APK cloner.
Apktool is a tool for reverse engineering Android apk files. It can disassemble resources to nearly original form and assemble rebuilt folders, including changing an app's permissions. It can also analyze by ripping apart resources and the manifest for inspection.
Bytecode Viewer is a Java reverse engineering suite with a GUI that includes Java and APK decompilers, bytecode editors and a compiler. It supports loading classes, jars and Android APKs, and is released as free and open source under GPL v3.
CheckFileType is a free online tool that determines a file's true type, extension and MIME type from its contents rather than its extension. Users upload a file without registration, and the tool can look inside archives such as ZIP files to report the type of each contained file. Files are stored temporarily and removed after one hour.
ColorHexa is a free color tool that provides information about any color and generates matching color palettes, such as complementary, analogous, triadic, tetradic and monochromatic schemes. Users enter a color value and it offers a detailed description and converts it to equivalent formats including Hexadecimal, RGB, CMYK, HSL, HSV and CIE-LAB.
Crackmes.one is a site for downloading crackmes to practice reverse engineering skills. Submitting a crackme or a solution requires registration. Downloads are password-protected. The site lists counts of users, crackmes and writeups, and offers auto-validated crackmes that earn points.
CrackMy.App is a community site for sharing crackmes and solving reverse engineering challenges. Users can upload crackmes, solve challenges from other users, earn points and climb a leaderboard, with sections for latest and popular crackmes and recent solutions.
Cutter is a free and open-source reverse-engineering platform powered by Rizin, using Rizin as its core engine. It is built with Qt and C++ and provides access to Rizin features through a GUI or an integrated terminal. Its releases integrate the native Ghidra decompiler, and it includes a graph view, debugger (beta), hex editor, Python scripting engine and plugins.
HexEd.it is a free hex editor that runs in a web browser using HTML5 and JavaScript technology. It is intended for Windows, MacOS, Linux and other modern operating systems, and lets users analyse hexadecimal binary dumps and files and read, manipulate, write, import and export byte as well as bit data.
A collection of guides and post-setup resources for homebrew on several game consoles, including Switch, Vita, 3DS, PS4, Wii U, Wii, DSi, PS3, Xbox 360, PS2 and GameCube. It also links to reverse engineering and CFW writeup material.
JavaDecompiler provides an online interface for extracting source code from .class and .jar binary files. It presents several Java decompilers, including CFR, JD, Procyon, Fernflower and JAD, with notes on each. The site also links to an APK decompiler and a knowledge base. JAD is listed for historical reasons only.
Nightmare is an introductory course on binary exploitation and reverse engineering built around CTF challenges. Its materials are structured linearly and include documented write-ups for each challenge, with most modules offering multiple problems per topic so learners can apply an attack technique to different iterations. The course uses only free and open source tools, and its static site is built with mdbook.
Online disassembler for inspecting executable files and assembly output during reverse engineering.
OverTheWire is a community offering wargames intended to help people learn and practice security concepts through games. Its suggested order begins with Bandit for Unix/Linux basics, followed by a choice among Natas for web security, Krypton for cryptography or Leviathan for reverse engineering, then binary exploitation games. Each shell game uses its own SSH port.
Pretendo Network is a free and open source replacement for Nintendo's servers for the 3DS and Wii U, built through clean-room reverse engineering. It aims to preserve online functionality for those consoles, and Cemu 2.1 officially supports it under network account options. Connecting on consoles requires hacks such as Aroma for Wii U and Luma3DS for 3DS, though Wii U also has a limited hackless SSSL method.
