    ModSecurity

    ModSecurity

    Cross platform web application firewall (WAF) engine for Apache

    ModSecurity is an open-source, cross-platform web application firewall (WAF) engine for Apache, IIS and Nginx that is developed by Trustwave's SpiderLabs. It has a robust event-based programming language that provides protection from a range of attacks against web applications and allows for HTTP traffic monitoring, logging and real-time analysis. Libmodsecurity is one component of the ModSecurity v3 project. The library codebase serves as an interface to ModSecurity Connectors taking in web traffic and applying traditional ModSecurity processing. In general, it provides the capability to load/interpret rules written in the ModSecurity SecRules format and apply them to HTTP content provided by your application via Connectors. Before starting the compilation process, make sure that you have all the dependencies in place.

    Qtum

    Qtum

    Qtum Core Wallet

    Qtum is a decentralized blockchain project built on Bitcoin's UTXO model, with support for Ethereum Virtual Machine-based smart contracts, and secured by a proof of stake consensus model. It achieves this through the revolutionary Account Abstraction Layer which allows the EVM to communicate with Qtum's Bitcoin-like UTXO blockchain. Welcome to the Qtum Ignition Main Network. This is the main network where the tokens hold value and should be guarded very carefully. If you are testing the network or developing unstable software on Qtum, we highly recommend using either testnet or regtest mode. A Proof of Stake consensus system which is optimized for Qtum's contract model. Any user can stake and help to secure the network. There is no voting, master nodes, or minimum amount required. There have been transactions as small as 2 Qtum that have created blocks in the past. Staking from smart contracts is under development.

    Al-Khaser

    Al-Khaser

    Public malware techniques used in the wild: Virtual Machine, Emulation

    al-khaser is an open-source proof-of-concept security tool that deliberately implements techniques commonly used by real-world malware to test and evaluate the effectiveness of antivirus and endpoint detection and response (EDR) systems. It’s written in C/C++ and designed to execute a wide range of anti-analysis, anti-debugging, anti-virtualization, timing-based evasion, and sandbox detection routines so security researchers and defenders can see how well their tools detect or ignore these behaviors. The project includes checks for debugger presence, stealthy anti-dumping measures, various VM and sandbox artifacts, and process injection techniques, giving you a broad view of how defensive tools respond under stress. al-khaser isn’t malicious by intent — its purpose is to help security teams identify gaps in their detection logic and harden defenses by simulating evasive behaviors without actual payloads.

    Blackbone

    Blackbone

    Windows memory hacking library

    Blackbone is a powerful Windows-focused memory manipulation and process interaction library intended for developers needing deep access to system internals, reverse engineering, or dynamic analysis tools. It provides a comprehensive API in C++ that allows allocation and management of virtual memory in local and remote processes, reading and writing remote process memory, enumerating loaded modules, creating and controlling threads, and performing complex pattern searches—all with support for both 32-bit and 64-bit architectures. Beyond basic memory operations, Blackbone includes advanced functionality for remote code execution, function hooking, and manual map features that let developers inject and manage modules in foreign processes without relying on the operating system’s loader mechanisms. It supports intricate use cases like injecting DLLs into target applications, performing remote hooks with hardware breakpoints, and handling cross-session thread creation.

    BoringSSL

    BoringSSL

    Mirror of BoringSSL

    BoringSSL is a Google-maintained fork of OpenSSL, designed specifically to meet the security, performance, and maintainability needs of Google’s infrastructure and products. While fully open source, BoringSSL is not intended for general public use — it serves as a streamlined, heavily modified SSL/TLS and cryptography library optimized for Google’s internal ecosystem, including Chrome/Chromium, Android, and other Google services. 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. BoringSSL includes comprehensive API documentation, build instructions, and guidance for porting code from OpenSSL.

    Osquery

    Osquery

    SQL operating system instrumentation and monitoring framework

    Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive. Osquery exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.Osquery queries your devices like a database. Osquery uses basic SQL commands to leverage a relational data-model to describe a device. Frequently, attackers will leave a malicious process running but delete the original binary on disk. This query returns any process whose original binary has been deleted, which could be an indicator of a suspicious process.
