Utilising Machine Learning Against Email Phishing to Detect Malicious Emails

Abstract

Phishing is an identity theft evasion strategy used in which consumers accept bogus emails from fraudulent accounts that claim to belong to a legal and real company in the effort to steal sensitive information of the client. This act places many users’ privacy at risk, and therefore researchers continue to work on identifying and improving current detection instruments. Classification is one of the machine learning methods that can be used to detect emails received. Different classification algorithms such as Naïve Bayes and Support Vector Machine (SVM) are discussed and compared in the course of this study. In an integration of the monitored and unregulated strategies, a new method has been developed to detect phishing emails. The research also contrasts the collection classes for manual and automatic emails. Series of terms are used to acquire words to differentiate between malicious and non-malicious communications in this research. In predicting the class attribute, the exactness of the different classifiers has been compared. SVM approach has the most reliable classification and misclassification rates of malicious emails than the Naïve Bayes method. To date, 98% precision was achieved, but if a researcher has a big corpus of training data, it can also be increased further. This research aims to investigate whether email phishing during a pandemic has been accelerated and the proposed research highlights that the phishing sensitivity is focused on the protocols utilised in this research. The key purpose is to express a technique or algorithm for the dissection of mailbox information in order to identify it as phishing or to include a genuine email. Machine Learning is a part of Artificial Intelligence (AI), which uses the knowledge mining method to recognise new or current trends (or highlights) of a data set which is then used for characterisation purposes. This study will discuss the advancement and types of phishing attacks. It will examine the Machine Learning techniques and methods which are currently being utilised. The researcher will further analyse a structure on how to avoid phishing as well as recommending methods which can be improved upon for email phishing. Furthermore, the important role of human behaviour is highlighted i.e., working from home during the pandemic.
