Drive By Download Attack Explained How Hackers Deliver Malware with JavaScript

In this lecture, we explore how hackers have historically used drive-by download techniques to deliver malware through malicious websites. Using a short JavaScript example, we break down how a webpage can automatically trigger the download of a malicious executable and attempt to run it on a victim’s system using older technologies like ActiveX and Windows Script Host. This video explains the purpose of each part of the code, how attackers tried to automate malware delivery in the past, and why modern browsers and security mechanisms now block most of these techniques. This lesson is intended for cybersecurity students, ethical hackers, and malware analysis learners who want to understand how client-side attacks work so they can better detect and defend against them.
