Attackers can bypass application whitelisting and executable restrictions by converting managed .NET assemblies into JScript loaders that execute in memory via Windows Script Host. The technique demonstrated uses DotNetToJScript to run x64 Meterpreter shellcode over HTTPS, blending into trusted components and evading binary-focused defenses. #DotNetToJScript #Meterpreter
Keypoints
- Application control often blocks unsigned .exe files while allowing script execution for legacy and administrative workflows.
- DotNetToJScript converts a managed .NET assembly into JScript, enabling in-memory execution via Windows Script Host.
- An x64 Meterpreter reverse_https payload can be embedded as shellcode and executed without touching disk to evade endpoint detections.
- Correct architecture selection (x64) and a controlled tooling pipeline are required for reliable payload execution.
- Defenders must consider execution context and script-based controls in addition to binary restrictions to mitigate this attack vector.
