• Phishing isa form of cybercrime inwhich a target iscontacted via
email, telephone, or text message by an attacker disguising as a
reputable entity or person.
• XBNet (Extremely Boosted Neural Network), is combination of
tree-based models with neural networks to create a robust
architecture.
• It is trained by using a novel optimization technique, Boosted
Gradient Descent for Tabular Data which increases its
interpretability and performance.
INTRODUCTION

The purpose of this project is to help individuals identify these
phishing URLs in order to provide safer practices online.
A popular model for tabular data is boosted trees, a highly
efficacious and extensively used XBNet classifier, and it also
provides good interpretability compared to neural networks
AIM OF THE PROJECT

Types of Phishing Tactics
96% of phishing attacks arrive by email.
3% of phishing attacks is done over the telephone.
This is also known as vishing.
1% of phishing attacks is done via text message.
This is known as smishing.
Email
Telephone
Text
Message

EXAMPLE

30%of phishing emails
are opened by users
12%of these targeted
users click on the
malicious link or
attachment.
97%of the users are
unable to recognize a
sophisticated phishing
email.

Feature Extraction
Lengthof URL,domain, path, query,and fragment
are extracted.
Quantity of specific characters in URL, domain,
path, query, and fragment are extracted. These
characters include:

Feature Extraction
Using a function from urllib library, protocol, domain, path, query, and
fragment were extracted from the URL and respective columns were created.
The protocol column was dropped as more sophisticated phishing URLs are
labeled secure with https:/.

MODEL
SELECTION &
EVALUATION

This architecture consists two parts.
Firstly, instead of randomly initializing weights for gradient
descent in the first iteration, we train our tree first and the feature
importance given by the tree are used as weights in the first
iteration.
Secondly, we decrease the magnitude of the value of feature
importance as given in the algorithm during backward propagation
so that instead of creating a big change in the weights, it just
slightly nudges it, thus not disrupting the process.

CONCLUSIONS

How to Avoid Phishing Attacks
ST
AY INFORMED
Learn about new phishing techniques
that are being developed to avoid
falling prey to one.
UTILIZE ‘FISHING FOR PHISHERS’
When in doubt, use the ‘Fishing for
Phishers’ app to verify the
authenticity of a website.
THINK BEFORE YOU CLICK
Never click on hyperlinks
without examining the hidden
URL.

XBNet requires more time and resources for training as we train a gradient-boosted
tree in every layer.
Currently, XBNet only works on tabular data and is unable to process unstructured
data. If it is extended for usage in unstructured data, the number of parameters will
see a drastic jump, and hence care has to be taken with respect to it.
LIMITATION AND FUTURE WORK

Thank you!
Any questions?
