    OWASP Juice Shop

    OWASP Juice Shop

    Probably the most modern and sophisticated insecure web application

    OWASP Juice Shop is probably the most modern and sophisticated insecure web application! It can be used in security trainings, awareness demos, CTFs and as a guinea pig for security tools! Juice Shop encompasses vulnerabilities from the entire OWASP Top Ten along with many other security flaws found in real-world applications! Juice Shop is written in Node.js, Express and Angular. It was the first application written entirely in JavaScript listed in the OWASP VWA Directory. The application contains a vast number of hacking challenges of varying difficulty where the user is supposed to exploit the underlying vulnerabilities. The hacking progress is tracked on a score board. Finding this score board is actually one of the (easy) challenges! Apart from the hacker and awareness training use case, pentesting proxies or security scanners can use Juice Shop as a "guinea pig"-application to check how well their tools cope with JavaScript-heavy application frontends and REST APIs.

    Flipper Zero Firmware

    Flipper Zero Firmware

    Flipper Zero firmware source code

    Flipper Zero is a portable multi-tool for pentesters and geeks in a toy-like body. It loves hacking digital stuff, such as radio protocols, access control systems, hardware, and more. It's fully open-source and customizable, so you can extend it in whatever way you like. Flipper Zero is a tiny piece of hardware with a curious personality of a cyber-dolphin. It can interact with digital systems in real life and grow while you use it. Explore any kind of access control system, RFID, radio protocols, and debug hardware using GPIO pins. The idea of Flipper Zero is to combine all the hardware tools you'd need for exploration and development on the go. Flipper was inspired by the pwnagotchi project, but unlike other DIY boards, Flipper is designed with the convenience of everyday usage in mind — it has a robust case, handy buttons, and shape, so there are no dirty PCBs or scratchy pins. Flipper turns your projects into a game, reminding you that development should always be fun.

    tfsec

    tfsec

    Security scanner for your Terraform code

    tfsec is a static analysis security scanner for your Terraform code. Designed to run locally and in your CI pipelines, developer-friendly output and fully documented checks mean detection and remediation can take place as quickly and efficiently as possible. tfsec takes a developer-first approach to scanning your Terraform templates; using static analysis and deep integration with the official HCL parser it ensures that security issues can be detected before your infrastructure changes take effect. Checks for misconfigurations across all major (and some minor) cloud providers. Applies (and embellishes) user-defined Rego policies. Supports multiple output formats: CLI, JSON, SARIF, CSV, CheckStyle, and JUnit. Configurable (via CLI flags and/or config file). Very fast, capable of quickly scanning huge repositories. Plugins for popular IDEs available (JetBrains, VSCode and Vim).

    UFONet

    UFONet - Denial of Service Toolkit

    UFONet is a powerful and controversial Python-based toolkit for testing and conducting Distributed Denial of Service (DDoS) attacks using unconventional methods, such as leveraging third-party web applications as attack vectors. It automates the discovery of vulnerable targets and enables attackers or researchers to launch large-scale amplification attacks without directly using botnets. While primarily intended for penetration testing and educational purposes, UFONet emphasizes anonymity through the use of proxies, TOR, and encrypted command channels.

    User Scanner

    User Scanner

    Scan usernames and emails across many platforms from the CLI

    user-scanner is a command-line OSINT tool designed to analyze the presence and availability of usernames and email addresses across many online platforms. It helps users quickly determine whether a specific username or email is already associated with accounts on social networks, developer platforms, creator communities, gaming services, and other sites. user-scanner is useful for security researchers, investigators, and analysts performing open source intelligence, as well as individuals or businesses looking for a unique username across multiple services. By scanning many platforms in a single command, it simplifies the process of checking account existence and identifying a digital footprint. user-scanner uses a modular architecture where each platform is implemented as a small validator module that determines whether a username exists or is available.

    Robin

    Robin

    AI-powered tool for dark web OSINT search and investigation

    Robin is an AI-powered open source tool designed to assist investigators and researchers in conducting dark web OSINT (Open Source Intelligence) investigations. It combines automated dark web search capabilities with large language models (LLMs) to analyze and summarize information discovered across hidden services and Tor-based search engines. The tool helps refine investigative queries, collect results from multiple dark web sources, and filter relevant intelligence using AI-driven processing. Robin also performs scraping of discovered pages through Tor sessions, allowing users to gather additional context from dark web sites while maintaining the required network routing. By integrating AI models, the platform can interpret results, highlight key information, and produce summaries that help analysts understand findings faster. The project provides a modular architecture separating search, scraping, and AI processing components so it can be extended with new data sources.

    https://github.com/The-Osint-Toolbox/Telegram-OSINT

    Telegram-OSINT is an extensive open source repository that compiles tools, techniques, and resources for conducting open source intelligence investigations on the Telegram platform. It serves as a central reference for analysts, researchers, and investigators who want to discover, analyze, and collect publicly available information from Telegram channels, groups, and bots. It organizes a wide variety of utilities that interact with Telegram’s API to gather data such as channel details, posts, and metadata, often exporting the results in formats like JSON for further analysis. The repository also includes utilities that help search for Telegram channels or process lists of channels from input files, making large-scale investigations easier to manage. In addition to direct data collection tools, it provides resources for channel discovery, similar channel analysis, and browser-based interfaces for interacting with Telegram data.

    Kraken is an online distributed brute force password cracking tool. It allows you to parallelize dictionaries and crunch word generator-based cracking across multiple machines both as a web app in a web browser and as a standalone electron-based client. Kraken aims to be easy to use, fault-tolerant and scalable. Kraken is a dockerized application using docker-compose which will launch the db (Postgres), s3-compliant file storage (Minio), the server and the browser client. You can find the docker-compose file in the root directory of the repository. To upload password lists or dictionaries, upload them to Minio Console at localhost:9001. View the steps explained for a detailed guide Otherwise, you can generate word lists dynamically using crunch. Window EXE portable client needs to run in the folder with its hashcat dependencies. Hashcat files can be downloaded from their home page.
