Hey everyone, I put together a small challenge for anyone interested in reversing .NET protections. This one is packed using .NET Reactor v7.5.9.1 with some pretty aggressive settings, along with a bit of custom anti-tamper logic on top. Your goal is to unpack the application and recover a clean, working assembly. Protections Enabled NecroBit String Encryption Obfuscation Anti ILDASM Hide Method Calls Code Virtualization Anti Tampering Anti Debug Merge Enums Control Flow Obfuscation (Level 9) Additional Protections Custom runtime anti-debug Anti-injection checks Integrity verification A background watchdog thread 🎯 Objectives 1. Primary: Unpack the application and produce a clean assembly that runs without errors 2. Bonus: Recover the correct password (completely optional)

hekliet keygemne #1

Mon, 16 Mar 2026 19:16:19 +0000

Not much to say there. Valid solution is a keygen that produces a valid key for any given name. Binaries for Linux and Windows are provided. Plain C, no symbols stripped, compiled with -O0, so should be fairly easy to follow. Difficulty is medium. Or perhaps easy for someone with some math knowledge. Here are some valid keys: Name: hekliet Key: 3fec806bc9ce82d4c00ee01af273a0b5 Name: Tuts 4 You Key: 40105e5bb69056bd3fdc1a4496fa9430 Name: Guybrush Threepwood Key: 400e09a63ee6d3a2bfd94d31f7369d10

Prometheus (12 Layers of Insanity)

Wed, 21 Jan 2026 06:41:49 +0000

A recruitment challenge for those who see what others cannot. The binary guards an encrypted message. To reveal it, you must provide the correct 28-character key. There is no backdoor, no shortcut, no unintended solution—only the key. The verification process spans twelve interconnected layers. Each depends on others. Disrupting one cascades through all. The binary knows its own shape and will notice if you change it. Some defenses are apparent through static analysis. Others manifest only at runtime. A few exist in the liminal space between instruction and execution—observable only through their effects, never their implementation. Difficulty 6/6 ## Rules - Standard crackme rules apply - The solution is the 28-character key - Picture of the solved challenge to be posted only 48h after completion. - No external services or network required - Linux x86_64 The reward prize and job offer will terminate in 24 hours.

CrackMe (Custom .NET JIT-Runtime)

Sat, 10 Jan 2026 11:50:08 +0000

The CrackMe I made has a special feature - custom jit. Bruteforce is not necessary. To launch, install .NET 10 To run the file, delete CrackMe.deps.json - this way the file will load the local runtime, and not from the root folder.

Cool Beans (License Challenge)

Good evening everyone, I’ve put together my first CrackMe using DNGuard 4.94 and its License Management feature. The application is called “Cool Beans.exe” - terrible name, I know 😄 Once cracked successfully, you’ll be taken to the main form, which displays a (slightly stupid) message. Hope you enjoy taking a look.

VMPLicenseProtector

Fri, 26 Dec 2025 06:10:06 +0000

This is a recently developed recreational utility. I'm unsure which forum section is appropriate, so moderators please feel free to move it if necessary. The tool implements a combined The Enigma and VMProtect protection scheme and is designed for applying VMProtect to Win32/Win64 executables and DLLs without requiring source code. It is not compatible with .NET assemblies. The interface supports Chinese/English language switching. To function, VMProtect_Con.exe must be placed in the tool's directory. Note that the tool itself is incompatible with Windows 7 and requires the DirectX 11 runtime to be installed. Software protected with it remains compatible with Windows XP/7/10. Trial Version Limitations: Only the anti-hijacking feature is enabled. All other functions are disabled. Uses a fixed RSA key. Please do not use it to protect commercial software. While some features are disabled, the tool may be sufficient for users with modest needs if patched. The trial license expires after one month, but functionality can be extended through patching. Archive Password: View by double-clicking the RAR file in WinRAR (check archive comment) or use: tuts4you. VMPLicenseProtector_Trial.rar

DNGuard HVM v4.94

Sat, 13 Dec 2025 13:13:03 +0000

Hey, Dropping my second UnpackMe challenge, made just for fun. This one’s a bit tougher than my first, but still very doable. The goal is to unpack and analyze the binary and reach the success message. Cracking it is extra, not required. It’s a simple .NET WinForms app that asks for a password and shows “Access granted” when the condition is met. The UI is trivial, the focus is on what’s happening once protections kick in. Protected with DNGuard HVM Enterprise. Source code, compiler-generated code, constructors, strings, managed resources, and blob heaps are encrypted. HVM and HVM II are both enabled at level 5, with proxy methods and additional runtime protections. Metadata is obfuscated, name heaps are destroyed, automatic renaming and dynamic control flow obfuscation are enabled, and basic anti-dump and anti-static measures are in place. The password is not stored in plaintext. Verification is done against a SHA-256 hex hash (PasswordSha256Hex). If you want to reverse or bypass that, that’s the crack portion and optional. Screenshots show the app and protection settings used.

Custom Python Obfuscator (CM)

Sat, 13 Dec 2025 04:10:25 +0000

Decryption doesn't involve modifying the Python interpreter; everything is done through code obfuscation. Password verification is performed via hash comparison—finding the correct hash to compare against counts as success. My custom obfuscator has just been released—come and give it a try! It includes techniques such as control-flow obfuscation, string encryption, virtualization, and C++ white-box implementation.

C++ x64 Protection

Mon, 03 Nov 2025 01:44:09 +0000

[ Crackme ] C++ x64 Protection Compiler: C++ (x64) Protection: Heavy obfuscation (control flow flattening, opaque predicates) Full code virtualization (custom VM with unique opcode set) Anti-tamper checks (integrity verification, debugger detection) Encrypted string/table storage Custom packer layering the entire binary Challenge: This is a server-client authentication system protected by a custom packer. The client executable performs login validation by communicating with a local/emulated server component. Goal: Patch the client to bypass authentication OR Emulate the server to allow successful login with any credentials You are free to choose either approach. Hint / Test Account: Username: testacc Password: testpass Notes: The packer is not a known public tool (e.g., ConfuserEx, KoiVM, VMProtect). It is fully custom-built. All network logic, crypto, and validation routines are virtualized and packed. Anti-debug and anti-analysis tricks are active. (it has fake section name called vmp2 that gives fake information to tools that looks like packed with vmp) Good luck, show your skills in unpacking, emulation, or clean patching!

r00t0 KeygenMe v4

Sat, 01 Nov 2025 20:01:22 +0000

Difficulty: 5 Language: C GCC Platform: x64 OS Version: Windows 10+ Packer / Protector : Selfmade Description : Implement keygenme that generate a serial derived from a nickname. Also demonstrate a generator that, given a nickname, produces the correct serial. I used my own tool that I've been developing for two years. It started as an optimizer, but I’m now experimenting with the reverse idea — using it to help with obfuscation and code retranslation.

AutoIt Custom Packer (Extract Image Files)

Sun, 10 Aug 2025 05:38:55 +0000

Hello everyone, I'm a AutoIt developer, and I've created a small portable program that uses a custom packer to protect some assets. The program is written in AutoIt and consists of two files: M-Dl.exe and assets.zip. I'm looking for skilled reverse engineers to test the security of my custom packer. The Goal: The challenge is to extract the image files that are contained within the custom packer. I've designed the packer with my own security techniques and would love to see how it stands up against the community's expertise. Repository & Download: You can find the project repository on GitHub, including the binary for download: https://github.com/yutijang/M-Dl I'm eager to learn from your findings and improve my security practices. Any feedback on the protection mechanisms, potential vulnerabilities, or how they were bypassed would be greatly appreciated. Thank you for your time and effort!
