If we could plot the lifespan of URLs, we could see that the oldest website has been online since Nov 7th, 2008, while the most recent phishing websites appeared as

If we could plot the lifespan of URLs, we could see that the oldest website has been online since Nov 7th, 2008, while the most recent phishing websites appeared as late as July 10th, 2023.

As we can see, there's no correlation between `not_indexed_by_google`, `is_malicious` and the columns `meta_percentage`, `mouseover_changes`, `right_click_disabled`, and `popup_window_has_text_field` as of July, 2023, contrary to some [analyses of researchers in 2013 on phishing detection](./Phishing_Websites_Features.docx).

The majority of features have very weak correlations with `is_malicious`, while a minority has a weak correlation. Is this problematic for training? Not really.

I split the classification task into two stages in anticipation of the limited availability of online phishing websites due to their short lifespan:
|

+
1. a small multilingual BERT model to output the confidence level of a URL being malicious to model #2, by finetuning on 2,154,175 legitimate and malicious URLs
|
12 |
+
2. (probably) LightGBM to analyze the confidence level, along with roughly 19 extracted features
|

|

This way, I can make the most out of the limited phishing websites avaliable.
