## What it is
Modlishka is an open-source penetration testing tool written in Go that acts as a transparent man-in-the-middle reverse proxy. It can proxy multi-domain TLS and non-TLS traffic over a single domain without client certificate installation, and was the first public tool demonstrating 2FA bypass via adversary-in-the-middle techniques.

## Use cases
- set up a reverse proxy for ethical phishing penetration tests
- demonstrate 2FA bypass weaknesses in security assessments
- wrap legacy websites with TLS
- transparently proxy arbitrary domains over HTTPS
- inject JavaScript payloads into proxied web traffic
- harvest credentials during authorized red team engagements

## When to choose
- you need a transparent AitM reverse proxy for authorized security testing
- you want to demonstrate 2FA weaknesses to clients or stakeholders
- you need to proxy multi-domain TLS traffic through a single domain
- you want a stateless proxy that scales via DNS load balancing

## When to avoid
- you need a general-purpose production reverse proxy like nginx or traefik
- you lack explicit authorization to test target systems
- you need a simple forward proxy or VPN solution
- your use case is defensive monitoring rather than offensive testing
