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. -

Scalytics Open Intelligence - OSINT
Open OSINT stack for monitoring, analysis, and risk detection
EUOSINT is the open-source edition of the OSINT pipeline built by Scalytics for real-world intelligence monitoring, situation analysis, and risk detection. It is not a toy dashboard or a loose script bundle. It is a packaged operational stack with a web interface, a Go-based collector runtime, configurable ingestion and refresh cadence, Docker-first deployment, and local or server installation options. The public release removes non-public and protected integrations while preserving the pipeline structure and deployment model that make the system usable in practice. EUOSINT is built for teams that need continuous monitoring, reproducible installs, and a base they can extend for their own intelligence and security workflows. -

Stegcore
A cross-platform crypto-steganography toolkit
Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there. Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible. Designed for journalists, security researchers, red teamers, digital forensics professionals, and CTF participants. -

tirreno
Open-source security framework for devs and product teams
tirreno is an open-source security framework. tirreno [tir.ˈrɛ.no] helps understand, monitor, and protect your product from threats, fraud, and abuse. While classic cybersecurity focuses on infrastructure and network perimeter, most breaches occur through compromised accounts and application logic abuse that bypasses firewalls, SIEM, WAFs, and other defenses. tirreno detects threats where they actually happen: inside your product. tirreno is a few-dependency, "low-tech" PHP/PostgreSQL application. After a straightforward five-minute installation, you can ingest events through API calls and immediately access a real-time threat dashboard. -

Naeon
The safest way to store private data in untrusted (cloud) environments
Naeon is a data encryption and sharding method designed to secure data in potentially untrusted off-site storage locations. It uses AES-256 encryption with a randomly generated passphrase, followed by obfuscation techniques to make the encrypted file unidentifiable. The data is then sharded into one private chunk containing the encryption key and part of the data, and multiple public chunks. Each chunk is renamed using its SHA-512 hash, and all chunks are timestamped equally. A filename conversion table is created to restore the concatenation order during a restore. The method aims to guarantee confidentiality, integrity, and availability of data, regardless of the trustworthiness of the chosen storage environment, while protecting against data breaches and unauthorized access. Threshold Key Sharing further enhances security and resilience by splitting the private key into parts requiring cooperation from multiple parties for reconstruction, thereby minimizing single points of failure. -
