## What it is
changeme is a Python CLI tool that scans networks for devices and services using default or backdoor credentials. Credential definitions are stored in YAML files, and it supports HTTP/HTTPS, SSH, databases, SNMP, FTP, and other protocols, with targets loadable from IPs, subnets, host lists, nmap XML, or Shodan queries.

## Use cases
- scan a subnet for devices with default passwords
- find default credentials on network services before a pentest
- check ssh and database servers for factory-set logins
- audit my network for backdoor credentials
- run a default credential scan from shodan results
- detect default logins on routers and appliances

## When to choose
- you need to detect default or backdoor credentials across many protocols
- you want to add new credential checks without writing code, just YAML
- you want to feed targets from nmap XML or Shodan queries

## When to avoid
- you need general brute-forcing of common or weak passwords rather than defaults
- you need a supported platform other than Linux without using Docker
- you need a full commercial-grade vulnerability scanner
