This is a simple UnpackMe using VMProtect Ultimate v2.13.5. I also used vmp's licensing system in this UnackMe, and locked one function with key. I have provided 3 different keys for this bin. A blocked key ,a valid key locked with a hwid(which i suppose no one has th same hwid) and an expire key. I also added 2 anti-debug thread to this file. Using VMProtectIsDebuggerPresent(if you have sod, i guess you can bypass this one pretty easy) and VMProtectIsValidImageCRC(crc). Didn't use VMProtectDecryptString feature. Several things I expect from this UM: Simply unpack it. Bypass the blacklist key. Bypass the expired situation. Patch hwid. Better create a …

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.

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
