About:
The chaos-client is a command-line interface tool designed to interact with the Chaos DB API, a comprehensive dataset of subdomains and DNS records. It enables security researchers and developers to efficiently query the database for reconnaissance and attack surface mapping. This tool streamlines the process of discovering exposed assets and subdomains during security assessments.
Key Features:
  • Fast querying of the Chaos DB for subdomain enumeration
  • Seamless integration with other security tools and workflows
  • Simple and intuitive command-line interface
  • Supports filtering and custom output formats
Use Cases:
  • Performing reconnaissance for penetration testing engagements
  • Mapping an organization's external attack surface
  • Gathering subdomain data for vulnerability research
Alternatives:
  • subfinder – subfinder is a broader subdomain discovery tool that uses multiple sources, while chaos-client specifically queries the ProjectDiscovery Chaos database.
  • amass – amass performs extensive network mapping and OSINT, whereas chaos-client is a focused client for a single data source.
