Patch and PatchNet

AMSI Patching

Patch Command:

This command patches AMSI to allow scripts written in pure powershell language to execute without interference from AMSI.

Please Note: AMSI patching may fail against AV vendors other than Defender.

PatchNET Command

Some PowerShell scripts, like Rubeus, load .NET assemblies via [System.Reflection.Assembly]::Load(). AMSI can catch binaries loaded through this method, making traditional AMSI bypasses ineffective. To address this, run the Patch command first then the PatchNET command before loading them.

Please Note: AMSI patching may fail against AV vendors other than Defender.
