## What it is
Evil Clippy is a cross-platform C# command-line assistant for crafting malicious MS Office documents with hidden or stomped VBA macros. It abuses MS-OVBA specifications to evade macro analysis tools and antivirus detection, and is intended for authorized testing and education.

## Use cases
- hide VBA macros from the Office GUI editor
- stomp VBA code via P-code to bypass antivirus
- confuse maldoc analysis tools during red team engagements
- serve VBA stomped templates over HTTP
- set or remove VBA project locked/unviewable protection
- test macro detection capabilities of security tools

## When to choose
- you are a red teamer or security researcher building test maldocs
- you need a cross-platform (Linux/OSX/Windows) macro evasion tool
- you want to evaluate antivirus and macro analysis tooling against VBA stomping

## When to avoid
- you want to create legitimate Office documents or macros
- you lack authorization for offensive security testing
- you need a maintained tool with binary releases or recent feature development

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: security, cli, developer-tools
- domain: security, penetration-testing
- platform: windows, cli, cross-platform
