Ghosting AMSI: Cutting RPC to disarm AV
published on 2025-04-25 17:45:30 UTC by /u/Echoes-of-TomorrowwContent:
🛡 AMSI Bypass via RPC Hijack (NdrClientCall3) This technique exploits the COM-level mechanics AMSI uses when delegating scan requests to antivirus (AV) providers through RPC. By hooking into the NdrClientCall3 function—used internally by the RPC runtime to marshal and dispatch function calls—we intercept AMSI scan requests before they're serialized and sent to the AV engine.
