A high-performance DNS stub resolver for bulk lookups and reconnaissance (subdomain enumeration)

Framework for Man-In-The-Middle attacks

CryptoLyzer is a fast, flexible and comprehensive server cryptographic protocol (TLS, SSL, SSH, DNSSEC) and related setting (HTTP headers, DNS records) analyzer and fingerprint (JA3, HASSH tag) generator with Python API and CLI. (read-only clone of the original GitLab project)

A collection of tools developed by other researchers in the Computer Science area to process network traces. All the right reserved for the original authors.

A multi-protocol proxy server written in Rust (HTTP, SOCKS5, Vmess, Vless, Shadowsocks, Trojan, Snell, Hysteria2, TUIC v5, AnyTLS, Naiveproxy, XTLS)

Boringtun is a Rust-based library and userspace implementation of the WireGuard protocol. It provides the necessary logic to establish encrypted network tunnels and route secure traffic across different operating systems without requiring kernel-level administrative privileges. The project is designed for embedding VPN logic into other applications. It achieves this through a C-compatible binary interface and cross-platform native bindings, allowing other programming languages to incorporate tunnel operations and peer management into their own software.

Zero-Trust access management with true WireGuard® 2FA/MFA

testssl.sh is a suite of diagnostic tools and a network security auditor used to scan network ports for supported encryption protocols, ciphers, and vulnerabilities in TLS and SSL configurations. It functions as a security scanner that evaluates the cryptographic strength of a server by testing all available cipher suites. The tool analyzes server encryption strength and identifies security vulnerabilities or weak settings through TLS and SSL security auditing. It verifies that encryption is properly implemented on specific network ports and evaluates whether only strong and modern encryption

EasyTier is a decentralized peer-to-peer virtual private network and mesh networking tool. It functions as a layer 3 network overlay that establishes secure tunnels between devices without requiring a centralized server or coordinator. It also serves as a WireGuard-compatible VPN, capable of acting as a server for standard WireGuard clients. The project distinguishes itself through multipath latency-based routing and the use of KCP or QUIC proxies to mitigate packet loss and stabilize connections in high-loss environments. It provides a virtual networking manager featuring a web management co

FakeNet-NG - Next Generation Dynamic Network Analysis Tool

Stunner is a tool to test and exploit STUN, TURN and TURN over TCP servers. TURN is a protocol mostly used in videoconferencing and audio chats (WebRTC).

This project is a security utility for aggregating threat intelligence and automating the deployment of high-performance firewall rules. It functions as an aggregator that fetches and normalizes malicious IP address lists from multiple external security feeds and a management tool that deploys these lists into the Linux kernel using ipset for packet filtering. The system maintains network perimeter defense by using atomic kernel updates to swap IP sets, which allows firewall rules to be updated without interrupting active connections. It includes a range optimizer that simplifies network addr

Stenographer is a packet capture solution which aims to quickly spool all packets to disk, then provide simple, fast access to subsets of those packets. Discussion/announcements at stenographer@googlegroups.com

An engine to make Tor network your default gateway

Terminal UI for WireGuard and OpenVPN with real-time telemetry and leak guarding.

Evilgrade is a modular framework that allows the user to take advantage of poor upgrade implementations by injecting fake updates.
