| Category | Count | Source File | Description |
|---|---|---|---|
| Benign | 50,000 | Benign_list_big_final.csv | Legitimate, safe URLs |
| Phishing | 20,000 | phishing_dataset.csv | Phishing attack URLs |
| Spam | 5,000 | spam_dataset.csv | Unwanted/spam URLs |
| Defacement | 7,000 | DefacementSitesURLFiltered.csv | Defaced websites |
| Malware | 5,530 | Malware_dataset.csv | Malware hosting URLs |
| Other | 3,530 | malicious_phish.csv | Additional malicious URLs |
| TOTAL | 87,530 | - | Combined Dataset |
Equal representation: 9,000 URLs per class (45,000 total)
Why Balance?
- Prevents bias toward majority class (benign)
- Improves model generalization
- Better performance on minority classes
- More reliable confidence scores
Algorithm: Extreme Gradient Boosting (XGBoost)
Model Parameters:
- Algorithm: Gradient Boosting Classifier
- Objective: Multi-class classification (softmax)
- Estimators: 100 boosting rounds
- Random State: 42 (reproducibility)
- Max Depth: Default (6)
Why XGBoost?
- Excellent performance on tabular data
- Fast training and inference
- Handles feature importance well
- Robust to outliers
- Production-ready
Features are extracted from URL structure and content:
- use_of_ip - Contains IP address instead of domain name
- url_length - Total length of the URL (in characters)
- hostname_length - Length of the hostname/domain
- fd_length - Length of first directory in path
- tld_length - Length of top-level domain (.com, .org, etc.)
- count. - Count of dots (.) in URL
- count@ - Count of @ symbols (suspicious)
- count% - Count of percent (%) signs (URL encoding)
- count- - Count of hyphens (-) in domain
- count= - Count of equal (=) signs (parameters)
- count-https - Count of HTTPS in URL
- count-http - Count of HTTP in URL
- count-www - Count of WWW in URL
- count_dir - Count of directory levels
- count_embed_domain - Count of embedded domains
- sus_url - Contains suspicious keywords (update, verify, account, login, etc.)
- abnormal_url - Abnormal URL structure patterns
- short_url - Uses URL shortening service (bit.ly, tinyurl, etc.)
- count-digits - Count of digits in URL
- count-letters - Count of letters in URL
Feature Rationale:
- Phishing URLs use IP addresses instead of domains
- Phishing URLs tend to be unusually long
- Malware sites use suspicious keywords
- Spam uses URL shorteners
- Each feature helps distinguish categories
