Build a Phishing Website Detection System Using Machine Learning

Create a machine learning-based system that identifies and blocks phishing websites by analyzing URL patterns and website features — a crucial project to bolster web security.

Why Develop a Phishing Detection System?

Phishing attacks are a prevalent threat in cybersecurity, tricking users into revealing sensitive information through deceptive websites. Traditional blacklists can't keep up with the rapid creation of new phishing sites. A machine learning-based detection system can analyze patterns and features to identify malicious websites in real-time, providing a proactive defense mechanism.

Core Features of the System

The system analyzes URLs and website content to extract features indicative of phishing. It employs machine learning models trained on datasets of legitimate and phishing websites to classify and detect threats. Users can input URLs to receive immediate risk assessments.

Key Features to Implement

URL Feature Extraction

Analyze URLs for characteristics common in phishing sites, such as length, use of symbols, and domain age.

Website Content Analysis

Inspect website elements like forms, scripts, and text to identify deceptive content.

Machine Learning Classification

Train models like Random Forest or SVM to classify websites based on extracted features.

Real-time URL Assessment

Allow users to input URLs and receive instant evaluations on their legitimacy.

How the System Works

The system processes input URLs by extracting relevant features and feeding them into a trained machine learning model. Based on the analysis, it classifies the URL as legitimate or phishing. This approach enables the detection of new and evolving phishing threats that traditional methods might miss.

Users input a URL into the system.
The system extracts features from the URL and associated website content.
Extracted features are processed by the machine learning model.
The model outputs a classification: 'Legitimate' or 'Phishing'.
Users receive the result with an explanation of the risk factors identified.
