Had this sitting around and thought I'd see what happens w/it here! Goal is to remove the kernel based protection, from inside the kernel (driver must be loaded). Or make any of the functions in the picture work.Any solution w/driver loaded is valid - patching, custom driver to unload protection, etc. X86.sys or X64.sys must be loaded.REQUIREMENTS:- Vista x86/x64 & newer (no xp) - Admin Privs - Test Mode Enabled INSTRUCTIONS: This requires driver test mode enabled. Before running, from an admin cmd prompt type the following, then restart -bcdedit /set TESTSIGNING on bcdedit /set loadoptions INTEGRITY_CHECKS_DISABLEDGood luck! MY_NAME_IS_LOADER.rar

Hi guys, here's a quite simple crackme and packed with enigma. Let's see if you can unpack it & crack it The "License scheme" Is very simple and only contains numbers. The goal is not to write the License denied message, but the other one Why is it ++? Because I tried to use Enigma as deep as possible I used markers, vm and some more. There are a few stuff which I couldn't figure out how to use, but I think it should be harder than simply unpacking an enigma. Link to download: http://ge.tt/1nlum7F2/v/0?c Good luck guys. Edit: Added file to the post Modified description a bit EnigmaCrackMe_protected.7z

Hi , Unpack The PEncrypt 4.0 Protector Youtube https://www.youtube.com/watch?v=pV7d9Rec-2M Tool : gunpacker GUnPacker.rar

Good luck UnpackMe.rar

it uses Qt5.4 GUI. the key validation algorithm is not difficult to analyze. but this Keygenme uses a lot of classes and templates which would be a great challenge for reverse engineering. have fun! OOKeyGenMe.7z

This is a simple keygenme designed to show a new feature in C# 6.0 (VS2015): catch-when exception filters. It's a part of my blog post. .NET Framework version: 2.0 Obfuscation: none, written in pure C# Difficulty: 2/10, should not take more than 30 minutes for a skilled reverser; Rules: #1 - It's a keygenme, so valid solution is a keygen (or valid username/pass, if you're really lazy). #2 - Please, please spend few minutes describing how you solved it. It will help everyone else to learn. #3 - Don't waste your time patching few bytes - you will not learn anything that way. #4 - Have fun! Cheers, kao. CatchMeWhen.zip

The objective is to unpack and crack this application and make it rune whithout error. Crack me_enigma.rar
