Dropper to DLL Injection: Red / Blue

*Dropper to DLL Injection: Red / Blue* This is part of a larger attack-chain that I am building out and wanted to share along the way. As usual, the simulation begins right after an initial access event has transpired but before execution of the dropper. The dropper (requirements.cmd) then goes ahead and starts the rdpclip.exe process in case it’s not active, parses for the process’s PID, setup.exe injects a DLL (Covenant C2 grunt) into process rdpclip.exe and that process then reaches out to the C2. Planning to add to this – some PrivSec, impairing defenses, persistence and an obfuscated C2 infrastructure.
 
Microsoft Defender for Endpoint (EDR+BlockMode+AutomtedInvestigations) vs Dropper->Start rdpclip.exe->Find PID->DLL Injection(Implant(Medium))->rdpclip.exe->CovenantC2==Zero alerts but there is always evidence…let’s have a look.
