SeedCrackerX
Minecraft mod designed to reverse-engineer
SeedcrackerX is a Minecraft mod designed to reverse-engineer and determine a world’s seed by analyzing in-game structures and environmental data. It operates by collecting information from structures such as shipwrecks, temples, and monuments, then using that data to progressively narrow down possible seeds until the correct one is identified. The mod automates much of this process, initiating cracking procedures once sufficient data has been gathered, often requiring only exploration of specific structures. It includes a graphical configuration interface that allows users to control which structures are used and how data is collected. The system can also integrate with a shared database to contribute discovered seeds, enabling collaborative data gathering across users. Advanced features include brute-force algorithms that refine seed candidates based on structural patterns and hashed seed calculations. -

Masscan
Mass IP port scanner
Masscan is an Internet-scale port scanner, able to scan the entire Internet in just 6 minutes or less. It's considered the fastest port scanner and is similar to the famous port scanner nmap, and like port scanners scanrand and unicornscan it uses asynchronous transmissions. However, it is more flexible when it comes to arbitrary port and address ranges. Masscan not only detects when ports are open, it can also check banners. And while it is useful for smaller, internal networks, it's designed with the entire internet in mind. Do take note however that Masscan uses its own custom TCP/IP stack, so anything other than a simple port scan could cause conflict with the local TCP/IP stack unless certain configurations are done. -

fsociety
Modular CLI framework for managing penetration testing tools
fsociety is a modular penetration testing framework designed to provide a unified interface for running and managing a wide range of security tools. It focuses on simplifying penetration testing workflows by integrating multiple external security utilities into a single command line environment. Instead of implementing its own security scanners, the framework acts as a wrapper and orchestrator that helps users discover, install, and execute tools from various GitHub repositories. Its modular architecture organizes tools into categories such as information gathering, networking, web application security, and password testing. This structure allows users to quickly navigate through different security tasks while maintaining a consistent interface. fsociety can automatically clone and manage required tools, reducing the manual effort typically needed to set up a penetration testing toolkit. fsociety is distributed as a Python package. -

OSINT Framework
OSINT Framework
OSINT-Framework is a web-based intelligence resource map designed to help investigators and researchers quickly locate free open-source intelligence tools and data sources. Rather than functioning as an automated scanner, it organizes hundreds of OSINT resources into a structured, navigable interface grouped by investigation type, such as usernames, email addresses, domains, and social media. The project was originally created from an information security perspective but has since expanded to support journalists, analysts, and digital investigators across many disciplines. Its value lies in curation and discoverability, allowing users to pivot rapidly between relevant intelligence tools during investigations. The framework includes indicators showing whether a resource requires registration, manual editing, or local installation, improving workflow planning. -

Vuls
Agentless vulnerability scanner for Linux/FreeBSD
Vuls is open-source, agent-less vulnerability scanner based on information from NVD, OVAL, etc. Vuls uses multiple vulnerability databases NVD, JVN, OVAL, RHSA/ALAS/ELSA/FreeBSD-SA and Changelog. Vuls v0.5.0 now possible to detect vulnerabilities that patches have not been published from distributors. Remote scan mode is required to only setup one machine that is connected to other scan target servers via SSH. If you don't want the central Vuls server to connect to each server by SSH, you can use Vuls in the Local Scan mode. Fast scan mode scans without root privilege, no internet access, almost no load on the scan target server. Deep scan mode scans in more detail. It is possible to acquire the state of the server executing some commands. Vuls v0.5.0 warns not-restarting-processes which updated before but not restarting yet. And detect processes affecting software update in advance.
