Could you build this?

Partial While wrapping the Microsoft Graph API is standard, building an in-memory Cobalt Strike User-Defined C2 (UDC) transport DLL with evasion considerations requires specialized offensive development expertise.

What it would actually take: The tool consists of a client-side C/C++ Beacon plugin adhering to Cobalt Strike's External C2 / UDC specification and an external server handler. The hard part is writing native C code that authenticates silently against Microsoft Graph without touching disk, polls OneDrive folders asynchronously, and avoids behavioral detection from enterprise EDR solutions.
