Abstract

Phishing is the process of enticing people into visiting fraudulent websites and persuading them to enter their personal information. Number in phishing email are spread with the aim of making web users believe that they are communicating with a trusted entity or organization. Phishing is deployed by the use of advanced and harmful tactics like malicious or phishing URLs. So, it becomes necessary to detect malicious or phishing URLs in the present scenario. Numerous anti- phishing techniques are in vogue to discriminate fake and the authentic website but are not effective. This research, focuses on the relevant URLs features that discriminate between legitimate and malicious/phishing URLs. The impact of email phishing can be largely reduced by adopting an appropriate combination of all these features with classification techniques. Therefore, an Enhanced Malicious URLs Detection (EMUD) model is developed with machine learning techniques for better classification and accurate results.

Highlights

  • Over the last decade phishing attacks have grown considerably in the internet

  • The phishers are using numerous phishing URLs crafting tactics pointing to the same phishing website to bypass the detection techniques [1]

  • In this research paper, supervised machine learning techniques (i.e. Naïve Bayes (NB) and Support Vector Machine (SVM)) to detect malicious URLs with the Enhanced Malicious URL Detection (EMUD) algorithm has been used with EMUD model

Summary

Introduction

Over the last decade phishing attacks have grown considerably in the internet. E-mail Phishing is presently amongst the latest, very tricky and problematic of trends in network security threats. A system can be technically safe and secure enough against password theft, naive users may leak their sensitive information if an attacker lead them to update their sensitive information such as username, passwords via a given Hypertext Transfer Protocol (HTTP) link [4]. It could breach the security of the system, web vulnerabilities like obfuscated/phishing URLs can be used by phishers to craft far more influencing socially-engineered messages.
