URL Guard - AI-Assisted Malicious URL Detection

Tue, 20 Jan 2026 00:00:00 +0300

A self-training, locally hosted phishing and malicious URL detector that combines machine learning, rule-based analysis, threat intelligence and AI into a single decision engine.

The problem it solves

Most URL checkers either look only at a blocklist — blind to fresh attacks — or return a single black-box score with no stated reasoning. URL Guard does both, and adds the judgement of a SOC analyst on top: it reads every piece of evidence, resolves the contradictions between them, and produces a reasoned verdict with a confidence score.

Fake Extension Builder

Sun, 25 Aug 2024 09:53:42 +0200

This project is a lightweight utility developed to obfuscate .exe file extensions by inserting the Braille Pattern Blank character (Unicode U+2800) just before the .exe suffix. The primary objective is to disguise the true nature of executable files in environments where basic file extension spoofing is relevant for educational, research, or cybersecurity awareness purposes.

Ryuk Ransomware

Sun, 25 Aug 2024 09:53:42 +0200

This project was developed to safely simulate and analyze how real-world ransomware operates within a controlled environment. Written in C#, this simulation uses AES encryption to lock files and places itself in system startup, accurately modeling the behavior of actual ransomware and providing a reliable test environment.

Note: This project was created solely for academic and educational purposes and must never be executed on real systems.
