Detect It Easy
Program for determining types of files for Windows, Linux and MacOS
Detect It Easy (DiE) is a tool for determining the type and internal features of binary and other file formats. It is widely used by malware analysts, digital forensics investigators, reverse engineers, and security researchers to quickly inspect unknown files and infer their type, architecture, compiler/packer used, and internal structure. DiE supports a large variety of file formats — from common executables (Windows PE, Linux ELF, macOS Mach-O) to archives, mobile packages (APK, IPA), legacy binaries, compressed or packed files, and more — making it a versatile first step in analysis or triage workflows. The tool offers both a graphical user interface as well as a command-line interface, allowing flexible use across environments (desktop, servers, automation). Its detection engine is signature-based, but also includes heuristics that help when signatures are missing or obfuscated. This helps when analyzing packed, compressed, or partially corrupted files. -

uBlock Origin
An efficient blocker for Chromium and Firefox
An efficient blocker add-on for various browsers. Fast, potent, and lean. uBlock Origin is not an "ad blocker", it is a wide-spectrum blocker, which happens to be able to function as a mere "ad blocker". The default behavior of uBlock Origin, when newly installed, is to block ads, trackers and malware sites through EasyList, EasyPrivacy, Peter Lowe’s ad/tracking/malware servers, Online Malicious URL Blocklist, and uBlock Origin's own filter lists. uBlock Origin (or uBlock₀) is not an ad blocker; it's a general-purpose blocker. uBlock Origin blocks ads through its support of the Adblock Plus filter syntax. uBlock Origin extends the syntax and is designed to work with custom rules and filters. Furthermore, the advanced mode allows uBlock Origin to work in default-deny mode, which mode will cause all 3rd-party network requests to be blocked by default unless allowed by the user. -

OSINT Framework
OSINT Framework
OSINT-Framework is a web-based intelligence resource map designed to help investigators and researchers quickly locate free open-source intelligence tools and data sources. Rather than functioning as an automated scanner, it organizes hundreds of OSINT resources into a structured, navigable interface grouped by investigation type, such as usernames, email addresses, domains, and social media. The project was originally created from an information security perspective but has since expanded to support journalists, analysts, and digital investigators across many disciplines. Its value lies in curation and discoverability, allowing users to pivot rapidly between relevant intelligence tools during investigations. The framework includes indicators showing whether a resource requires registration, manual editing, or local installation, improving workflow planning. -

OWASP Juice Shop
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 scoreboard. Finding this scoreboard is actually one of the (easy) challenges!

RedAmon
AI-powered framework for automated penetration testing and red teaming
RedAmon is an AI-powered red team framework designed to automate offensive cybersecurity operations from reconnaissance to exploitation and post-exploitation. It combines artificial intelligence with traditional penetration testing tools to create a fully autonomous pipeline capable of discovering vulnerabilities and executing security assessments without human intervention. It begins with a multi-phase reconnaissance engine that maps the entire attack surface of a target, collecting information such as subdomains, open ports, services, and potential vulnerabilities. RedAmon then uses an AI agent orchestrator to analyze this data, select appropriate tools, and perform exploitation steps such as credential brute forcing or CVE-based attacks. All discovered assets, relationships, and vulnerabilities are stored in a Neo4j knowledge graph, allowing the system to reason about the environment and make informed decisions during the attack process. -
