## What it is
Singularity of Origin is a DNS rebinding attack framework that includes a DNS server, a web server, a management UI, and sample attack payloads. It rebinds an attacker-controlled domain to a target machine's IP address to exploit vulnerable software, ranging from home page capture to remote code execution.

## Use cases
- perform DNS rebinding attacks against vulnerable web applications and APIs
- test whether internal network services are reachable from a browser
- demonstrate DNS rebinding risks on IoT devices
- serve custom attack payloads to exploit vulnerable software versions
- research browser protections like Local Network Access and DoH against rebinding
- run a demo DNS rebinding attack with a web-based manager UI

## When to choose
- you need a ready-made, actively maintained DNS rebinding framework with sample payloads
- you are a security researcher or pentester assessing browser-based attacks on internal networks
- you want to study or demonstrate DNS rebinding techniques including IPv6 and LNA bypasses

## When to avoid
- you need general-purpose penetration testing beyond DNS rebinding
- you want a defensive tool to block rebinding rather than perform attacks
- your target browsers enforce Local Network Access without the trial token, which blocks Singularity's techniques
