bettercap is a powerful, easily extensible and portable framework written in Go which aims to offer to security researchers, red teamers and reverse engineers an easy to use, all-in-one solution with all the features they might possibly need for performing reconnaissance and attacking WiFi networks, Bluetooth Low Energy devices, wireless HID devices and Ethernet networks.

• WiFi networks scanning, deauthentication attack, clientless PMKID association attack and automatic WPA/WPA2 client handshakes capture.
• Bluetooth Low Energy devices scanning, characteristics enumeration, reading and writing.
• 2.4Ghz wireless devices scanning and MouseJacking attacks with over-the-air HID frames injection (with DuckyScript support).
• Passive and active IP network hosts probing and recon.
• ARP, DNS and DHCPv6 spoofers for MITM attacks on IP based networks.
• Proxies at packet level, TCP level and HTTP/HTTPS application level fully scriptable with easy to implement javascript plugins.
• A powerful network sniffer for credentials harvesting which can also be used as a network protocol fuzzer.
• A very fast port scanner.
• A powerful REST API with support for asynchronous events notification on websocket to orchestrate your attacks easily.
• A very convenient web UI.
• More!

bettercap is made with ♥ by the dev team and it's released under the GPL 3 license.
