Responder vs JD-GUI vs Bettercap: Which 3D Icons tool is Best in 2025?

Responder is a robust, open-source tool designed for network penetration testing, specializing in Link-Local Multicast Name Resolution (LLMNR), NetBIOS Name Service (NBT-NS), and Multicast DNS (mDNS) poisoning. Pre-installed on Kali Linux, Responder enables cybersecurity professionals and ethical hackers to intercept network authentication requests, capture NTLM hashes, and perform man-in-the-middle (MITM) attacks by mimicking legitimate servers. Developed by Laurent Gaffié, it targets Windows environments where LLMNR and NBT-NS are enabled by default, making it a powerful tool for credential harvesting and network security assessments.

JD-GUI is an open-source, standalone graphical Java decompiler, available on Kali Linux at /usr/bin/jd-gui, designed for reverse-engineering compiled Java applications by extracting readable source code from .class or .jar files. Developed by Emmanuel Dupuy and packaged for Kali by Sophie Brun, JD-GUI provides a user-friendly GUI to browse class hierarchies, view decompiled Java code, and save sources as .java files. Ideal for cybersecurity researchers, Android developers, and ethical hackers, it supports malware analysis, code auditing, and vulnerability research. Often paired with tools like Dex2Jar, JD-GUI simplifies Java bytecode analysis.

Bettercap is a powerful, open-source, and modular network security tool designed for penetration testers, security researchers, and ethical hackers. Pre-installed on Kali Linux, it serves as a Swiss Army knife for network reconnaissance, man-in-the-middle (MITM) attacks, and traffic manipulation across Wi-Fi, Bluetooth Low Energy (BLE), Ethernet, and IPv4/IPv6 networks. Written in Go, Bettercap offers a flexible framework with an intuitive web UI, scriptable proxies, and caplets for automating complex attack scenarios.
