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. -

The package checks locally available tools and can bootstrap supporting scripts, MCP servers, and utilities when needed. Scope gates, case initialization, timelines, evidence chains, reports, and field journals encourage repeatable and auditable work. It supports clients such as Claude Code, Codex CLI, Cursor, and Cline across Windows, Linux, macOS, and Kali Linux. The repository also preserves reusable lessons so later investigations can avoid previously documented mistakes. -

Naeon
The safest way to store private data in untrusted (cloud) environments
Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the encryption key and part of the data — and multiple equal-sized public chunks, each renamed to its SHA-512 hash and given a uniform timestamp to prevent metadata inference. A private filename conversion table preserves the concatenation order needed for restoration. Together these measures guarantee confidentiality, integrity, and availability regardless of storage provider trustworthiness. Threshold Key Sharing extends this further by splitting the private key, eliminating the single point of failure. -

GUN
Cybersecurity protocol for syncing decentralized graph data
GUN is a small, easy, and fast data sync and storage system that runs everywhere JavaScript does. The aim of GUN is to let you focus on the data that needs to be stored, loaded, and shared in your app without worrying about servers, network calls, databases, or tracking offline changes or concurrency conflicts. This lets you build cool apps fast. When a browser peer asks for data, it'll merge the reply with its own data using a CRDT, then cache the result. GUN is fully decentralized (peer-to-peer or multi-master), meaning that changes are not controlled by a centralized server. A server can be just another peer in the network, one that may have more reliable resources than a browser. You save data on one machine, and it will sync it to other peers without needing a complex consensus protocol. It just works. GUN can be used in both browsers and servers. We have made it easy to install in many different environments. -

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. -
