This article studies the Browser-in-the-Middle (BITM) attack, a modern form of man-in-the-middle (MitM) attack in which an attacker controls or blocks web traffic by exploiting browser vulnerabilities and user’s web browsing. We delve deeper into the mechanics of the BITM attack, examining how malicious actors can inject scripts, hijack sessions, and manipulate data to gain unauthorized access and exfiltrate data. Using the Browser Exploit Framework (BeEF) tool, we simulated the BITM attack to demonstrate its impact and effectiveness in a controlled environment. To combat this threat, we propose a robust solution that involves the development of a browser extension designed to detect and mitigate BITM attack vectors. This extension uses real-time monitoring, traffic analysis, and user alerts to improve browser security, thereby providing an additional layer of protection against malicious activities such as So. Our findings highlight the importance of proactive security measures to protect user data and maintain the integrity of web communications.
