bettercap
Network reconnaissance and assessment framework for 802.11, BLE, HID, and CAN bus security assessments with modular extension support.
Technical Architecture & Overview
Bettercap is a network reconnaissance and assessment framework for 802.11, BLE, HID, and CAN bus. It can scan networks, capture packets, and run scripted modules for WiFi, Bluetooth, and Ethernet protocols. The framework is extensible through modules and a JavaScript-based module API.
Targeted Technical Use Cases
Use Bettercap to audit wireless and wired networks, capture protocol traffic, and validate the security of Bluetooth and CAN bus devices.
Evaluation & Trade-offs
Core Strengths
- +Supports many wireless and wired protocols in a single framework.
- +Has a modular architecture and a JavaScript API for custom modules.
- +Runs on Linux, macOS, and Windows with pre-built binaries.
Trade-Offs & Limitations
- -Some wireless features need specific adapters with monitor mode support.
- -Misconfigured modules can disrupt network traffic and nearby devices.
Defensive Security Application
Use Bettercap during authorized wireless audits to identify weak protocols, rogue access points, and unencrypted traffic, then implement mitigation controls.
