    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

    Hello, this is my first CrackMe, but I think is very hard because I haven't seen this method yet. Sorry for 2mb file, but linking is very much size. There is a function which returns true/false for Login, patch it to true and you did it. Might be super easy or super hard, idk! Good luck CrackMe.zip

Crack open your laptop and head to the dancefloor w/this latest challenge wooooo hoooooo yeaaahhhh!!Intro:The original project was done by a team who's coders I've learned a lot from and respect. When it gets broken I'll post the orig. credits + source + custom mods + toolsThere's some stupid stuff in there, not trying to be fancy/complicated. The original project was flagged by just about every AV, so I had to briefly change some things to drop the rates to 10/55.Despite false positives, there's nothing malicious about this, the code is easy to read - do confirm yourself.
