Challenge of Reverse Engineering

hey guys, as some of you may already know, I've been working on an obfuscator for quite a long time. https://www.disguiser.net/ There is still a lot of stuff to improve, but I' like to know, how long it takes an experienced reverser to code a Keygen for this. All features are present in normal mode, so I still have something harder in case this is too easy for you guys I'd rate it 6/10, let me know what you think PS. it might not be the best nor innovative, but its mine! if you find my hidden messages, you will get something from me (yeah, plural! and PM me for your small gift, once you found them) greetz li0nsar3c00l [RTN] Keygen…

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.
