Awesome GitHub RepositoriesDNS Responders

Sing-box is a universal proxy engine and traffic router designed to manage complex network connectivity across multiple operating systems. It functions as a configuration-driven core that intercepts system-level traffic, allowing for transparent proxying through encrypted tunnels. By normalizing diverse network protocols into a unified interface, the engine enables consistent traffic forwarding and protocol translation regardless of the underlying environment. The project distinguishes itself through a declarative configuration pipeline that validates and merges modular settings into a unifie

Webhook.site is a web-based tool that captures, inspects, and debugs incoming HTTP requests and emails sent to a unique URL, without requiring any server setup. It also functions as an API mocking and response modification tool, capable of generating mock APIs from OpenAPI specifications and altering HTTP responses, headers, and status codes for testing purposes. Beyond inspection, it serves as a platform for webhook automation and workflow orchestration, triggering multi-step automations—including database queries, SSH commands, and HTTP calls—when a webhook is received. The service distingu

Responder is a network penetration testing tool that intercepts and spoofs link-local name resolution queries, including LLMNR, NBT-NS, and mDNS, to redirect traffic to an attacker-controlled host. It hosts rogue protocol servers for over 15 protocols, capturing authentication credentials during challenge-response handshakes, and stores captured hashes and cleartext credentials in a SQLite database for structured offline analysis. The tool distinguishes itself through its ability to relay captured NTLM authentication challenges to target services for lateral movement without cracking the hash

Fluxion is a wireless security auditing framework that tests WPA/WPA2 networks by capturing handshakes and deploying rogue access points with captive portals. It operates by deauthenticating clients from legitimate access points, forcing them to reconnect to a cloned network where a fake authentication page collects the network passphrase. The tool distinguishes itself through a plugin-based attack lifecycle with mandatory hook functions for consistent execution, multilingual metadata scripts that load attack descriptions based on locale, and a handshake verification pipeline that validates c

Responder is a man-in-the-middle framework and network protocol spoofing tool designed to intercept network name queries and impersonate requested resources. It functions as a poisoner for LLMNR, NBT-NS, and MDNS, redirecting network traffic from clients to a controlled listener. The project serves as a credential capture tool that runs rogue servers for SMB, HTTP, and LDAP to collect NTLM hashes and clear text credentials. It enables the harvesting of encrypted authentication tokens and the interception of usernames and passwords sent without encryption. Its broader capabilities include int

Maskphish is a comprehensive security toolkit that integrates capabilities for digital forensics, network vulnerability scanning, open-source intelligence, penetration testing, and social engineering. It functions as a multi-purpose framework for automating reconnaissance and executing security audits across diverse network environments. The project features a specialized phishing and social engineering toolkit used for cloning websites, masking URLs, and deploying deceptive pages to capture user credentials. It also includes a remote access Trojan builder for generating platform-specific exe
