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. -

FlareSolverr
Proxy server to bypass Cloudflare protection
FlareSolverr is a proxy server to bypass Cloudflare and DDoS-GUARD protection. FlareSolverr starts a proxy server, and it waits for user requests in an idle state using few resources. When some request arrives, it uses puppeteer with the stealth plugin to create a headless browser (Firefox). It opens the URL with user parameters and waits until the Cloudflare challenge is solved (or timeout). The HTML code and the cookies are sent back to the user, and those cookies can be used to bypass Cloudflare using other HTTP clients. Web browsers consume a lot of memory. If you are running FlareSolverr on a machine with few RAM, do not make many requests at once. With each request, a new browser is launched. It is also possible to use a permanent session. However, if you use sessions, you should make sure to close them as soon as you are done using them. It is recommended to install using a Docker container because the project depends on an external browser that is already included. -

BlockTheSpot
Video, audio & banner adblock/skip for Spotify
BlockTheSpot is an open-source modification tool designed to block advertisements and bypass certain limitations in the Spotify desktop application for Windows. It works by patching the Spotify client and injecting custom logic that prevents audio, video, and banner ads from being displayed or played during usage. The tool focuses primarily on performance and ad suppression rather than cosmetic changes, ensuring that playback remains uninterrupted. It includes configurable options that allow users to enable or disable features dynamically, often through developer settings or configuration files. The project operates at a low level by modifying application components, which makes it effective but also susceptible to breaking when Spotify updates its software. It has gained popularity as a workaround for ad-supported tiers, though it requires manual installation and maintenance. -

HiJackThis
A free utility that finds malware and other threats
-- WARNING -- HiJackThis is an inactive project and it is not updated anymore. You may want to look at the existent unofficial forks though: https://github.com/dragokas/hijackthis/ -- HijackThis is a free utility that generates an in depth report of registry and file settings from your computer. HijackThis scan results make no separation between safe and unsafe settings , which gives you the ability to selectively remove items from your machine. In addition to scan and remove capabilities, HijackThis comes with several useful tools to manually remove malware from your computer. However, HijackThis does not make value based calls between what is considered good or bad. It is important to exercise caution and avoid making changes to your computer settings, unless you have expert knowledge. Source code is available SourceForge, under Code and also as a zip file under Files. -

mkcert
Zero-config tool to make locally trusted development certificates
mkcert is a simple tool for making locally-trusted development certificates. It requires no configuration. Using certificates from real certificate authorities (CAs) for development can be dangerous or impossible (for hosts like example.test, localhost or 127.0.0.1), but self-signed certificates cause trust errors. Managing your own CA is the best solution, but usually involves arcane commands, specialized knowledge and manual steps. mkcert automatically creates and installs a local CA in the system root store, and generates locally-trusted certificates. mkcert does not automatically configure servers to use the certificates, though, that's up to you. The CA certificate and its key are stored in an application data folder in the user's home. You usually don't have to worry about it, as the installation is automated, but the location is printed by mkcert -CAROOT. -

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. -

FLARE VM
A collection of software installations scripts for Windows systems
FLARE VM is a security-focused Windows workstation distribution designed for malware analysis, reverse engineering, penetration testing, and threat hunting. It bundles a curated set of tools—disassemblers, debuggers, decompilers, virtualization, forensics utilities, packet capture tools, exploit frameworks, and hex editors—preconfigured to work together. The environment configures paths, dependencies, environment variables, and common tool integrations so analysts can focus on tasks rather than setup. Updates and modular installation let users include only the tools that match their workflow, keeping the VM lean and current. Because security toolchains often clash (DLL versions, signing, privileges), FLARE VM’s packaging handles compatibility issues ahead of time. For investigations involving malware unpacking, sandboxing, static analysis, or code reversing on Windows, the platform dramatically accelerates readiness and consistency across analysts. -
