AegisLink is a Python/FastAPI backend API that analyzes suspicious URLs, explains possible risks in simple language, stores analysis history, and generates Markdown-style security reports.

✨ O

AegisLink is a defensi backend project designed to help users understand why a link may be risky.

Instead of simply saying safe or unsafe, AegisLink breaks down the URL into understandable signals:

The goal is not to prove that a website is malicious.
The goal is to provide static, educational, defensi that helps users make safer decisions.

🧠 Why I Built This

Many people click links without understanding what makes a URL suspicious.

I built AegisLink because I wanted to create a backend system that explains security risks clearly. This project helped me practice backend architecture, API design, database modeling, cybersecurity logic, and AI-style explanation generation.

AegisLink is also part of my hackathon portfolio. It shows that I can build a real backend service with practical security use cases, clean documentation, and a working API flow.

🦋 Butterfly Architecture Scheme

AegisLink is designed like a butterfly:
the left wing receives and analyzes the URL, the center performs the core risk decision, and the right wing stores results and generates reports.

🔥 Core Features

| Feature | Description |
|---|---|
| URL Analysis | Parses and normalizes submitted URLs |
| Static Security Checks | Detects suspicious URL patterns without the website |
| Risk Scoring | Calculates a 0–100 risk score |
| Risk Levels | Classifies links as LOW, MEDIUM, HIGH, or CRITICAL |
| Human Explanation | Generates clear AI-style explanations |
| Safe Recommendations | Suggests defensive user actions |
| History Storage | Stores previous analysis results |
| Markdown Reports | Generates readable security reports |
| OpenAPI Docs | FastAPI-powered interactive API documentation |

🛡️ Detection Rules

AegisLink uses rule-based static analysis.

| Rule | What it Detects |
|---|---|
| Missing HTTPS | Links that do not use secure HTTPS |
| Missing Scheme | URLs submitted without http:// or https:// |
| Suspicious Keywords | Words like login, , password, payment, bank, wallet |
| Long URL | URLs that are unusually long |
| Very Long URL | URLs that may hide suspicious content |
| IP Address Domain | URLs using an IP address instead of a domain |
| Too Many Subdomains | Domains with suspiciously deep nesting |
| Suspicious TLD | TLDs such as .zip, .mov, .click, .top, .xyz, .loan |
| URL Shortener | Services like bit.ly, tinyurl.com, t.co |
| Brand Impersonation Hint | Brand-like names used in suspicious contexts |

> AegisLink does not claim that a URL is definitely malicious. It only identifies static risk signals.

🧠 What This Project Demonstrates

AegisLink demonstrates:

---

🎯 Hackathon Relevance

AegisLink is built as a hackathon-ready backend project.

It shows that I can take a real-world security problem, design a clean backend system, implement useful API endpoints, generate readable explanations, and document the project clearly.

This project is not just a script.
It is structured like a real backend service.

---

🔐 Safety Note

AegisLink is defensive and educational only.

It does not:

AegisLink only performs static URL pattern analysis to help users understand possible risk signals.
