New Process Parameter Poisoning Technique Targets Windows EDR Solutions

• •Process Parameter Poisoning (P³) allows shellcode injection via Windows startup parameters.
• •The technique can evade detection by four major EDR solutions.
• •No active exploitation has been confirmed, but a proof of concept exists.

A new technique called Process Parameter Poisoning (P³) has been documented, allowing attackers to inject shellcode into legitimate Windows processes by manipulating startup parameters. This method enables attackers to bypass detection by four leading Endpoint Detection and Response (EDR) solutions. The P³-Shellcode Loader proof of concept demonstrates how this technique can reduce the visibility of malicious activities that traditional remote-process injection methods expose. While the specific impact scope and affected systems are not detailed, the technique poses a significant risk to organizations relying on EDR tools for threat detection. Currently, there are no confirmed reports of in the wild, but the existence of a proof of concept raises concerns for potential future attacks.
