## What it is
MITMf is a Python framework for performing Man-In-The-Middle and network attacks, featuring built-in SMB, HTTP, and DNS servers, an SSLStrip-based proxy, and modular plugin support. The project is explicitly no longer maintained, with the author recommending Bettercap instead.

## Use cases
- intercept and modify HTTP traffic on a local network
- capture credentials from protocols like FTP, SMTP, and NTLMv2
- perform SSL stripping attacks with partial HSTS bypass
- spoof DNS and SMB responses during a pentest
- filter and manipulate arbitrary network packets on the fly
- build custom MITM attack plugins in Python

## When to choose
- you need a modular Python framework to prototype a custom MITM attack
- you are studying legacy MITM techniques or doing historical security research
- you must run an old pentest lab environment that depends on MITMf plugins

## When to avoid
- you want a maintained MITM tool - use Bettercap instead
- you need Python 3 support, since MITMf requires Python 2.7
- you need modern TLS/HSTS bypass capabilities
- you want long-term support or bug fixes
