WinLicense v3.2.2 (Window Function Through an External Plugin) This is a WinLicense 3.2.2/sample, set by default, without adding an SDK in the source code, only adding a window function through an external plugin. I don't know if bypass can be cracked, I tested it and it doesn't. Shedding may be more complicated.Please use your own way to crack it. Whether it's molting, bypass, or keygen, they are all the best methods. No need to upload your proposal, posting a picture is the best answer. I will strive to learn towards your achievements.

Themida & VMProtect (Same Virtualized Code Sections) I want you guys who are capable of unvirtualizing and unpacking them to upload the final ones. These files are just the same part of the codes virtualized which are 2 lines of the original mfc source codes. So if you can unvirtualize them and unpack them, please upload the final ones. Any other protections are excluded absolutely. Give it a try and improve your skills. Best Regards. sean. File Information Submitter lovejoy226 Submitted 04/07/2025 Category UnPackMe View File

.NET KeyGenMe by Freddy #1 Hey there! I made this KeyGenMe because I enjoy playing chess. This challenge is written in .NET and involves some mathematical operations, mixed with a few chess-related twists. Your task is to figure out the logic behind generating a valid serial key based on the username you enter. But be warned—it’s not as simple as just moving a pawn forward ( maybe a hint ) Protection used : None. Goals : 1. Provide valid combination for Username - Serial Key ( Bronze ) 2. Fully KeyGen it - every username with different serial key algorithm ( Silver ) 3. Full KeyGen plus EXPLANATION on what u did and how you figured o…

Eclipse Runtime Obfuscator Hey everyone, I’m sharing an UnpackMe challenge that combines VMProtect packing with runtime function obfuscation using Eclipse Runtime Obfuscator. This should be an interesting challenge for those who enjoy working with dynamic obfuscation and anti-debugging techniques. Protection Details: VMProtect is used for basic packing, with import protection and anti-debug enabled. Eclipse Runtime Obfuscator dynamically obfuscates function execution, making dumped analysis and debugging difficult. Function code is relocated to a new memory region at runtime and accessed through vectored exception handling (VEH) instead of…

BinaryShield (Custom VM) This is my first attempt at a binary protector. Currently, the VM has very little protection, so this should be good for those interested in learning about VM-based obfuscation. I intend on uploading new challenges that feature my protector as I add more features. GOAL: - You must find the correct key. Simply patching to get a goodboy message is NOT allowed. - Bonus points for devirt and explanation of your approach. - MOST IMPORTANTLY, have fun! :) File Information Submitter ra1n Submitted 09/23/2024 Category CrackMe View File
