DMitry vs SET vs Responder: Which Discord Bot tool is Best in 2025?

DMitry is a command-line utility included in Kali Linux for passive information gathering during penetration testing and ethical hacking. Written in C, it collects public data about a target host, including subdomains, email addresses, uptime information, open TCP ports, and whois details for domains and IP addresses. DMitry also retrieves Netcraft data, such as operating system and web server details. Its lightweight design, with a 50 KB installed size, makes it ideal for quick reconnaissance, reducing the need for multiple tools. Key features include customizable TCP port scanning with TTL settings, filtered port reporting, and banner grabbing.

SET, or Social-Engineer Toolkit, is a leading open-source framework pre-installed in Kali Linux (version 8.0.3), designed for ethical hackers and penetration testers. This social engineering toolkit for cybersecurity automates attacks like phishing, credential theft, and payload delivery, making it a premier penetration testing tool for social engineering assessments. With a 30.40 MB footprint and over 10 attack vectors, SET empowers red teams to simulate real-world threats, integrating seamlessly with Metasploit for robust security testing.

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.
