legba
The fastest and more comprehensive multiprotocol credentials bruteforcer / password sprayer and enumerator. 🥷
Legba is a high-performance multiprotocol credentials bruteforcer and password sprayer built in Rust that can be integrated as an AI agent skill. Security researchers and penetration testers can install this skill into AI coding assistants like Claude Code, Cursor, or Copilot to enable the agent to construct legba commands, write authentication recipes, and configure its REST API or MCP server. The tool supports over 20 protocols including HTTP, SSH, FTP, SMTP, RDP, databases, LDAP, and Kerberos with async architecture for maximum performance.
