Bettercap is an extensible framework for network security testing that provides a unified interface for performing man-in-the-middle attacks, network reconnaissance, and traffic manipulation across WiFi, Bluetooth, and wired networks. It operates through a modular attack module system that loads and executes interchangeable offensive or diagnostic modules, supported by event-driven session management and multi-protocol network spoofing capabilities.
The framework distinguishes itself by covering a broad range of network domains, including Bluetooth Low Energy scanning and enumeration, CAN-Bus network analysis for automotive security testing, IPv4/IPv6 host and service discovery, and WiFi security assessment with tools for deauthentication, rogue access points, and packet injection. It also includes wireless HID attack simulation for injecting keystrokes into target computers over wireless connections.
Bettercap provides packet-level traffic manipulation through raw socket access and protocol-aware injection, along with network identity spoofing to redirect traffic through an attacker-controlled system. A real-time web UI dashboard streams live attack data and module outputs to a browser-based interface using WebSocket and REST APIs.
