Phishing URL Detector (XGBoost)

Live demo: https://phishing-website-detector-k5mb3cndcjkvrkcfaypexz.streamlit.app/ Source code: https://github.com/6305-0026-1762/phishing-website-detector

MSc Dissertation model: A Deep Learning Framework for Phishing Website Detection Using URL and HTML Features. Student: Sushma Singahalli Parashuramappa (250638286). Supervisor: Bo Wei.

XGBoost classifier trained on a combined dataset of 21,260 URLs from two independent sources (Hannousse & Yahiouche + an independent 835k-URL corpus, deduplicated across sources). Uses 37 lexical features extracted from the URL string alone (no HTML content or live page data) — see feature_names.joblib for the exact feature order and the companion url_features.py extractor.

Test set performance

Accuracy: 0.9104
F1-score: 0.9100
ROC-AUC: 0.9657
False positive rate: 8.5%

Files

xgboost.joblib - the trained model.
scaler.joblib - StandardScaler fitted on the training split; apply before prediction.
feature_names.joblib - exact feature order the model expects.

Usage

python

from huggingface_hub import hf_hub_download
import joblib, numpy as np

model = joblib.load(hf_hub_download("Twinkytuffy/phishing-url-detector-model", "xgboost.joblib"))
scaler = joblib.load(hf_hub_download("Twinkytuffy/phishing-url-detector-model", "scaler.joblib"))
feature_names = joblib.load(hf_hub_download("Twinkytuffy/phishing-url-detector-model", "feature_names.joblib"))

# feats = extract_url_features(url)  # see url_features.py
# x = scaler.transform([[feats[n] for n in feature_names]])
# proba_phishing = model.predict_proba(x)[0, 1]

Known limitation

The training data's legitimate class skews toward short, bare domains rather than www.-prefixed global brands, so some well-known root-domain-only URLs can land close to the 50% decision boundary. This is a dataset-composition limitation of the lexical-only feature set, not a bug — see the dissertation's overfitting/underfitting analysis (Section 5.6) for a full discussion.
