GhostTrack
Useful tool to track location or mobile number
GhostTrack is an open-source OSINT utility designed to help users gather publicly available intelligence related to IP addresses, phone numbers, and online usernames through a command-line workflow. The project is implemented in Python and targets cybersecurity researchers, ethical hackers, and investigators who need a lightweight reconnaissance tool for digital footprint analysis. It provides a menu-driven interface that allows users to select different tracking modes, making the tool accessible even to those with limited scripting experience. GhostTrack can be combined with complementary tools such as Seeker to enhance IP capture workflows and improve investigative coverage. Because it focuses on aggregating open data rather than exploiting systems, the tool positions itself within the information-gathering phase of security assessments and OSINT research. -

BerserkArch
A bleeding-edge, security-centric Arch-based Linux distribution.
BerserkArch is a security-focused, performance-tuned Linux operating system (OS) based on Arch Linux, designed for developers, hackers, and technical users. A bleeding-edge, security-centric Arch-based Linux distribution crafted for hackers, developers, and nerds alike. Following the Arch Linux philosophy, it is designed to be highly customizable, allowing users to build their environment with only the components they need, rather than having a lot of pre-installed software like some other security distributions (e.g., Kali Linux). As an Arch-based distribution, it benefits from the rolling release model, providing users with the latest software versions and kernel updates. BerserkArch is a dist "designed to make you powerful" for specific use cases like reverse-engineering binaries and automating exploits, rather than being an easy-to-use distribution for general beginners. -

SafeLine
Serve as a reverse proxy to protect your web services from attacks
SafeLine is a self-hosted WAF(Web Application Firewall) to protect your web apps from attacks and exploits. A web application firewall helps protect web apps by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web apps from attacks such as SQL injection, XSS, code injection, os command injection, CRLF injection, LDAP injection, XPath injection, RCE, XXE, SSRF, path traversal, backdoor, brute force, HTTP-flood, bot abuse, among others. By deploying a WAF in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a WAF is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server. A WAF protects your web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application. -

pyWhat
Identify emails, IP addresses, and more
pyWhat is a Python-based identification tool designed to figure out “what” a piece of text or file content represents, especially in security and OSINT workflows. Given inputs such as hex strings, URLs, email addresses, IP addresses, credit card numbers, cryptocurrency wallets, or entire .pcap capture files, it scans for structured patterns and tells you what it finds. The tool is recursive: it can traverse files and directories to extract meaningful entities, which is useful when analyzing malware samples, network captures, or code repositories at scale. It offers powerful filters called “tags” and distributions that let you narrow results to specific categories like bug bounties, cryptocurrencies, or AWS-related artifacts. For automation and integration, pyWhat provides a CLI with options for rarity filtering, sorting, and JSON export, as well as an API that can be imported into other Python programs. -

Network Enumeration Tool
Network Enumeration Tool for Host Exploration and Recon
N-ETHER (Network Enumeration Tool for Host Exploration and Reconnaissance) is a robust and highly automated Python script designed to streamline the critical initial phases of network security auditing and penetration testing. It’s core purpose is to perform fast, comprehensive, and consistent host and port discovery across single targets or large lists of IP addresses. N-ETHER functions as an intelligent, opinionated wrapper around the powerful nmap tool, bundling best-practice scanning techniques—including service versioning, NSE scripting, and intelligent port selection—into a single, easy-to-use utility. This significantly reduces auditor workload and potential for human error compared to manually executing multiple complex nmap commands. Read the README!!! -
