Demiguise is a Python CLI tool from NCC Group that generates HTML files containing RC4-encrypted HTA payloads, which are decrypted dynamically in the browser at runtime. It is designed for red team operations to bypass content/file-type inspection by security appliances and evade sandboxing via environmental keying.
Use cases
- encrypt an HTA payload inside an HTML page to evade proxy inspection
- generate HTA files for red team phishing simulations
- bypass security appliance file-type filtering
- use environmental keying to avoid sandbox detonation
- deliver payloads without plaintext HTA over HTTP
- test detection of encrypted HTA delivery techniques
When to choose
- you are a red teamer needing to deliver HTA payloads past content inspection
- you want encrypted, browser-decrypted payload delivery with environmental keying
- you need a lightweight Python tool for offensive HTA generation
When to avoid
- you need to author sophisticated HTA payload content itself
- you are building defensive tooling rather than offensive simulations
- you need a maintained tool with recent updates or broad platform support
