Responder vs Edb-Debugger: Which Custom GPU Kernels 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.

Edb-Debugger, pre-installed on Kali Linux at /usr/bin/edb, is an open-source, cross-platform graphical debugger for x86 and x86-64 binaries, inspired by OllyDbg but designed for Linux, with ongoing ports to FreeBSD, OpenBSD, macOS, and Windows. Developed by Evan Teran, EDB (Evan’s Debugger) leverages the ptrace API and Capstone disassembly library to provide a modular, extensible platform for reverse engineering and malware analysis. With its intuitive GUI, plugin-based debugging core, and support for conditional breakpoints, it’s a vital tool for cybersecurity researchers, ethical hackers, and forensic analysts.
