# UACMe
* Defeating Windows User Account Control by abusing built-in Windows AutoElevate backdoor.

# System Requirements

* x86-32/x64 Windows 7/8/8.1/10 (client, some methods however works on server version too).
* Admin account with UAC set on default settings required.

# Usage

Run executable from command line: akagi32 [Key] [Param] or akagi64 [Key] [Param]. See "Run examples" below for more info.

First param is number of method to use, second is optional command (executable file name including full path) to run. Second param can be empty - in this case program will execute elevated cmd.exe from system32 folder.

* Several methods require process injection, so they won't work from wow64, use x64 edition of this tool;
* Method (4) unavailable in 64 bit edition because of Shim restriction;
* Method (6) unavailable in wow64 environment starting from Windows 8. Also target application unavailable in Windows 10;
* Method (11) implemented in x86-32 version;
* Method (13) implemented only in x64 version.

Run examples:
* akagi32.exe 1
* akagi64.exe 3
* akagi32 1 c:\windows\system32\calc.exe
* akagi64 3 c:\windows\system32\charmap.exe

# Warning
* This tool shows ONLY popular UAC bypass method used by malware, and reimplement some of them in a different way improving original concepts. There are exists different, not yet known to general public methods, be aware of this;  
* Using (5) method will permanently turn off UAC (after reboot), make sure to do this in test environment or don't forget to re-enable UAC after tool usage;
* Using (5), (9) methods will permanently compromise security of target keys (UAC Settings key for (5) and IFEO for (9)), if you do tests on your real machine - restore keys security manually after you complete this tool usage;
* This tool is not intended for AV tests and not tested to work in aggressive AV environment, if you still plan to use it with installed bloatware AV soft - you use it at your own risk;
* Some AV may flag this tools as HackTool, MSE/WinDefender constantly marks it as malware, nope;
* If you run this program on real computer remember to remove all program leftovers after usage, for more info about files it drops to system folders see source code.
