## What it is
A curated collection of PowerShell scripts demonstrating various Antimalware Scan Interface (AMSI) bypass and avoidance techniques gathered from security blog posts. It serves as a reference for red teamers and security researchers testing Windows AMSI defenses.

## Use cases
- bypass AMSI during penetration tests
- learn how AMSI evasion techniques work
- test endpoint detection against AMSI bypasses
- find a working AmsiScanBuffer patch technique
- study scriptblock smuggling and CLR hooking methods
- evaluate Windows antimalware logging bypasses

## When to choose
- you are a red teamer needing a reference of AMSI bypass techniques
- you are researching Windows AMSI internals and evasion
- you want to test whether your EDR detects known AMSI bypasses

## When to avoid
- you need production security tooling with support or a license
- you want guaranteed undetected bypasses - most scripts are signatured and need manual modification
- you are not working on Windows or with PowerShell
