SharpStrike - A Post Exploitation Tool Written In C# Uses Either CIM Or WMI To Query Remote Systems

SharpStrike is a post-exploitation tool written in C# that uses either CIM or WMI to query remote systems. It can use provided credentials or the current user's session.

Note: Some commands will use PowerShell in combination with WMI, denoted with ** in the --show-commands command.

Introduction

SharpStrike is a C# rewrite and expansion on @Matt_Grandy_'s CIMplant and @christruncer's WMImplant.

SharpStrike allows you to gather data about a remote system, execute commands, exfil data, and more. The tool allows connections using Windows Management Instrumentation, WMI, or Common Interface Model, CIM ; well more accurately Windows Management Infrastructure, MI. CIMplant requires local administrator permissions on the target system.

Setup:

It's probably easiest to use the built version under Releases, just note that it is compiled in Debug mode. If you want to build the solution yourself, follow the steps below.

Load SharpStrike.sln into Visual Studio
Go to Build at the top and then Build Solution if no modifications are wanted

The Build will produce two versions of SharpStrike: GUI (WinForms) & Console application. Each version implements the same features.
