## What it is
A penetration testing tool that intercepts SSH connections by running a patched OpenSSH v7.5p1 server as a proxy between a victim and their intended SSH server. It logs plaintext passwords, shell sessions, and SFTP sessions to disk, relying on users ignoring host key change warnings.

## Use cases
- intercept ssh connections during a penetration test
- capture ssh passwords on a lan with arp spoofing
- log ssh shell and sftp sessions of targets
- demonstrate ssh man-in-the-middle attack risks
- find potential ssh targets on a local network
- audit whether users ignore ssh host key warnings

## When to choose
- you are an authorized auditor testing ssh credential exposure on a lan
- you need a ready-made dockerized ssh mitm proxy with session logging
- you want to demonstrate host-key-warning fatigue to clients

## When to avoid
- you need a general-purpose ssh proxy or bastion for production use
- you want a maintained tool with recent updates and broad platform support
- you are not authorized to test the target network
- you need a pure-python or easily extensible mitm framework
