The article discusses an advanced technique for bypassing the Anti-Malware Scan Interface (AMSI) using RPC hijacking through the NdrClientCall3 function. By intercepting the scan requests at the RPC level, this method manipulates the data before it reaches antivirus engines, allowing malware to evade detection without modifying AMSI itself. This approach operates deeper than traditional bypass methods, making it more effective against both signature and behavior-based detection systems.
