Abstract

This study provides an in-depth exploration of malevolent attacks targeting Internet of Things (IoT)
devices and the associated security issues stemming from unauthorized access. It presents a detailed
examination of different types of attacks, including data theft, device malfunctions, and the
dissemination of false results. The study also addresses the security concerns raised by unauthorized
attacks and proposes effective solutions. Furthermore, it offers comprehensive insights into
safeguarding IoT devices and data, presenting advanced preventive measures to counter malevolent
and unauthorized attacks.
Keywords: Malevolent attack, unauthorized access, data breach, Man-in-the-Middle attack, botnet,
cyber-attacks
INTRODUCTION
The increased susceptibility of an Internet-of-Things network to malicious assaults is one of the main
difficulties. Numerous academics have noted that heterogeneity, operation in an open environment,
scalability, limitations of IoT devices, resource limitations, high-security deployment, and operational
expenses are the principal issues in the security of the World Wide Web of Things. The interconnected nature of an IoT network makes it extremely vulnerable to unwanted attacks and allows for easy data sharing and communication between devices [1]. These attacks can take several different forms, such as network hijacking to seize control of devices, getting unauthorized access to sensitive data, or data breaches where private information is made public due to insufficient security measures.
