    MalwareSourceCode

    MalwareSourceCode

    Collection of malware source code for a variety of platforms

    ...Collections include proof-of-concept samples, older malware families, analysis-related libraries, phishing pages, and web panels. The structure makes it easier for security researchers to locate examples from different eras and ecosystems. Because the repository contains potentially dangerous code, it is intended to be handled only in controlled research environments with appropriate security precautions.

    BoringSSL

    BoringSSL

    Mirror of BoringSSL

    ...The project prioritizes security, simplicity, and maintainability over backward compatibility. Unlike OpenSSL, BoringSSL provides no guarantee of stable APIs or ABIs, meaning third-party projects depending on it may frequently break. Google products that use BoringSSL ship their own copies and update them as needed, enabling faster iteration without legacy constraints.

    Swift Crypto

    Swift Crypto

    Open-source implementation of a substantial portion of the API

    Swift Crypto is a cross-platform, open-source implementation that mirrors a substantial portion of CryptoKit so server and Linux/Windows ARM64 apps can share one modern crypto API. It exposes high-level, misuse-resistant primitives with Swift ergonomics while delegating to well-vetted backends under the hood. The repository maintains active releases and issue tracking for enhancements like PEM handling and ecosystem compatibility. High-level, misuse-resistant primitives and key handling....

    gVisor

    gVisor

    Application Kernel for Containers

    ...Written in Go, it implements a Linux-compatible system call interface that runs entirely in user space, creating a secure sandboxed environment for containers. Unlike traditional virtual machines or lightweight syscall filters, gVisor follows a third approach that offers many of the security benefits of virtualization while maintaining the speed, resource efficiency, and flexibility of containers. Its key runtime, runsc, integrates seamlessly with container ecosystems such as Docker and Kubernetes, making it easy to deploy sandboxed workloads using familiar tools. By intercepting and safely handling syscalls from applications, gVisor reduces the attack surface of the host kernel, mitigating risks associated with running untrusted or potentially malicious code in containerized environments.

    Capslock

    Capslock

    Tool to remap Caps Lock key behavior on Windows systems

    ...Rather than detecting vulnerabilities, Capslock focuses on identifying capabilities — permissions implied by calls to sensitive or privileged standard library functions, such as file system access, networking, or process control. By following transitive call graphs, it classifies which security-sensitive operations each package can reach, giving developers visibility into what their dependencies are capable of doing. This helps apply the Principle of Least Privilege to Go software, guiding audits, supply chain reviews, and trust assessments. Capslock aims to make security posture analysis more proactive by surfacing capability-based risk signals before malicious or overly powerful code is introduced into production.

    malware_training_vol1

    Materials for Windows Malware Analysis training (volume 1)

    ...It is designed to help learners understand common malware techniques through programming, reverse engineering, and Windows internals concepts. The material focuses on analysis rather than active misuse, making it useful for students, security researchers, and defenders building foundational skills. It includes exercises that explain how malware-like behaviors can be recognized and studied in a controlled lab context. The project also demonstrates how analysis tools can be used to inspect binaries, understand execution behavior, and reason about malicious code. Its main value is giving learners structured practice with real malware-analysis concepts while keeping the content oriented toward research and defense.
