Language: .NET Platform: Windows x32/x64 OS Version: Tested on Windows 10, with .NET 4.6.2 Packer / Protector: WinterStorm 0.1 (Personal Project) Description: Here is a project I've been working on for the last 6 months. It's a follow-up to my previous DynamicMethod attempts. This time I also included some simple JIT hooking. Everything here was written by myself, except a helper class for loading dlls from memory. I hope you'll find it entertaining. I can't wait to hear your thoughts. This is (arguably) the best iteration of the popular game, MineSweeper. Unfortunately, it's a demo, and it only allows for 5 moves. In order to keep playing you have …

Language : .NET Platform : .NET/Mono OS Version : All Packer / Protector : Custom Description : This is something I've stopped working on over the last few months, but if someone's interested in taking up the project with me I'll gladly accept.

Difficulty : 4-5 Language : .NET Platform : .NET/Mono OS Version : All Packer / Protector : Custom Description : This is a virtualizer I wrote over the last few days, basing most its protection on simple virtualization obfuscation, as well as constant local shuffling in order to make debugging a bit harder.

Difficulty : 9 Language : .NET Platform : Windows OS Version : 7 and above Packer / Protector : just dynamic methods (custom solution) Description : I learned a lot while building my original dynamic methods crackme so I decided to take it up a notch and created a new version. This one works the same: it asks for a name and a serial code, and if the serial is valid for the given name, it displays an ID calculated from the name. The goals are to either make the program calculate the ID without checking the serial, or build a keygen that creates valid serials. One pair of name and serial is provided. I tried to make it impossible to dump the dynamic …

Difficulty : 4 (I don't know) Language : C# .NET Platform : Windows OS Version : 7 and above Packer / Protector : Custom tool written from scratch and Obfuscar Description : Here is a project I've been working on for a few days. The protection algorithm is all written by myself (pretty basic though). I am basically a noob, so it might just be crap. However, I'd appreciate if someone could take a look at it, and provide some instructions on how to crack it. In the end, I ran the dlls through Obfuscar, for some simple renaming. The program takes two strings: a name, and a serial. Then it checks if the given serial is valid for the given name. If so…
