PHP OAuth 2.0 Server
A spec compliant, secure by default
league/oauth2-server is a standards compliant implementation of an OAuth 2.0 authorization server written in PHP which makes working with OAuth 2.0 trivial. You can easily configure an OAuth 2.0 server to protect your API with access tokens, or allow clients to request new access tokens and refresh them. The latest version of this package supports PHP 7.2, PHP 7.3, PHP 7.4, PHP 8.0. The openssl and json extensions are also required. All HTTP messages passed to the server should be PSR-7 compliant. This ensures interoperability with other packages and frameworks. The library uses PHPUnit for unit tests. We use Github Actions, Scrutinizer, and StyleCI for continuous integration. In order to prevent man-in-the-middle attacks, the authorization server MUST require the use of TLS with server authentication as defined by RFC2818 for any request sent to the authorization and token endpoints. The client MUST validate the authorization server’s TLS certificate as defined by RFC6125. -

Password Guessing Framework
A Framework for Comparing Password Guessing Strategies
The Password Guessing Framework is an open source tool to provide an automated and reliable way to compare password guessers. It can help to identify individual strengths and weaknesses of a guesser, its modes of operation or even the underlying guessing strategies. Therefor, it gathers information about how many passwords from an input file (password leak) have been cracked in relation to the amount of generated guesses. Subsequent to the guessing process an analysis of the cracked passwords is performed. In general though, any guesser that prints the password candidates via STDOUT can be used with the framework. The aforementioned password guessing / password cracking software is not part nor shipped with the framework and need to be installed separately. -

Tsunami
Network security scanner for detecting severity vulnerabilities
Tsunami is a general purpose network security scanner with an extensible plugin system for detecting high severity vulnerabilities with high confidence. When security vulnerabilities or misconfigurations are actively exploited by attackers, organizations need to react quickly in order to protect potentially vulnerable assets. As attackers increasingly invest in automation, the time window to react to a newly released, high severity vulnerability is usually measured in hours. This poses a significant challenge for large organizations with thousands or even millions of internet-connected systems. In such hyperscale environments, security vulnerabilities must be detected and ideally remediated in a fully automated fashion. To do so, information security teams need to have the ability to implement and roll out detectors for novel security issues at scale in a very short amount of time. Furthermore, it is important that the detection quality is consistently very high. -

s2n-quic
An implementation of the IETF QUIC protocol
s2n-quic is AWS’s open-source implementation of the IETF QUIC transport protocol, written in Rust and designed for performance, security, and modern usage. QUIC is a UDP-based, multiplexed, encrypted transport layer that underpins HTTP/3 and addresses issues such as head-of-line blocking and faster handshake times compared to TCP+TLS. This library integrates with AWS’s s2n-tls or rustls for the TLS 1.3 handshake and leverages Rust’s memory and thread safety guarantees to deliver a robust implementation. It is built with configurability in mind—you can tune congestion control (like CUBIC), pacing, packet size discovery, and other advanced network behaviors. Extensive testing (unit, fuzz, interop) ensures protocol compliance and interoperability with other implementations. Because it is open-source under Apache 2.0, organizations can integrate it into services where low latency, multiple streams, or mobility (connection migration) matter. -
23
sRDI
Shellcode implementation of Reflective DLL Injection
sRDI is a compact project that implements a shellcode form of Reflective DLL Injection, enabling DLLs to be converted into position-independent shellcode and loaded in memory by a small in-process PE loader. The codebase groups a C implementation of a reflective PE loader with multiple loader/wrapper components (native C loader, a .NET loader, Python and PowerShell conversion helpers) so authors can produce and embed sRDI blobs in different environments. The loader aims to behave like a proper PE loader: it preserves section permissions, supports TLS callbacks, performs sanity checks, and exposes flags to control behaviors such as header clearing, memory wiping, import obfuscation, and whether the shellcode receives the base address. The repository also provides utility scripts to convert DLL binaries into embedded blobs and to update static encodings used by the supplied loaders. -

secator
Automated framework for running pentesting tools and workflows
Secator is a task and workflow runner designed to streamline security assessments by integrating many well-known penetration testing and reconnaissance tools into a unified framework. It acts as a centralized automation platform that helps security professionals run tasks, workflows, and scans more efficiently from a single command-line interface. It supports dozens of established security tools and organizes them into structured workflows, enabling users to perform complex reconnaissance and vulnerability discovery processes with minimal manual effort. By standardizing input parameters and output formats across different tools, Secator simplifies how results are collected and processed during security testing. Secator is built to improve productivity for penetration testers, bug bounty hunters, and security researchers who frequently chain multiple tools together during assessments. -

tirith
Your browser catches homograph attacks
Tirith is a terminal security guardrail that inspects what you paste or run in your shell and blocks or warns on suspicious patterns before execution, addressing an area where terminals traditionally provide almost no protection. It targets real-world attack classes like Unicode homograph URLs (lookalike domains), terminal injection tricks (ANSI escape sequences and bidi overrides), and “pipe-to-shell” installation patterns such as curl | bash that attackers frequently abuse. The project emphasizes local-only analysis with no telemetry and no background daemons, so it can run offline and keep sensitive command context on-device. It integrates into popular shells via hooks (zsh, bash, fish, and PowerShell), including paste-aware protections so hidden characters or malicious rewrites get caught at the moment they enter the terminal.
