\outl0\strokewidth0 \strokec2 function Invoke-Mimikatz\
.SYNOPSIS\
This script leverages Mimikatz 2.0 and Invoke-ReflectivePEInjection to reflectively load Mimikatz completely in memory. This allows you to do things such as\
dump credentials without ever writing the mimikatz binary to disk. \
The script has a ComputerName parameter which allows it to be executed against multiple computers.\
This script should be able to dump credentials from any version of Windows through Windows 8.1 that has PowerShell v2 or higher installed.\
Function: Invoke-Mimikatz\

License: http://creativecommons.org/licenses/by/3.0/fr/\
Required Dependencies: Mimikatz (included)\
Optional Dependencies: None\
Version: 1.5\
ReflectivePEInjection version: 1.1\
Mimikatz version: 2.0 alpha (2/16/2015)\
.DESCRIPTION\
Reflectively loads Mimikatz 2.0 in memory using PowerShell. Can be used to dump credentials without writing anything to disk. Can be used for any \
functionality provided with Mimikatz.\
.PARAMETER DumpCreds\
Switch: Use mimikatz to dump credentials out of LSASS.\
.PARAMETER DumpCerts\
Switch: Use mimikatz to export all private certificates (even if they are marked non-exportable).\
.PARAMETER Command\
Supply mimikatz a custom command line. This works exactly the same as running the mimikatz executable like this: mimikatz "privilege::debug exit" as an example.\
.PARAMETER ComputerName\
Optional, an array of computernames to run the script on.\
.EXAMPLE\
Execute mimikatz on the local computer to dump certificates.\
Invoke-Mimikatz -DumpCerts\
.EXAMPLE\
Execute mimikatz on two remote computers to dump credentials.\
Invoke-Mimikatz -DumpCreds -ComputerName @("computer1", "computer2")\
.EXAMPLE\
Execute mimikatz on a remote computer with the custom command "privilege::debug exit" which simply requests debug privilege and exits\
Invoke-Mimikatz -Command "privilege::debug exit" -ComputerName "computer1"\
.NOTES\
This script was created by combining the Invoke-ReflectivePEInjection script written by Joe Bialek and the Mimikatz code written by Benjamin DELPY\
