WMI Based Agentless Post-Exploitation PowerShell RAT: WMImplant
WMI Based Agentless Post-Exploitation PowerShell RAT
WMImplant is a PowerShell based tool that leverages WMI to both perform actions against targeted machines, but also as the C2 channel for issuing commands and receiving results. WMImplant will likely require local administrator permissions on the targeted machine. It is designed to run both interactively and non-interactively. When using WMImplant interactively, it’s designed to have a menu of commands reminiscent of Meterpreter.
