What is a drive-by download?

A drive-by download refers to a situation where a program or file is automatically downloaded onto a user's device without their explicit consent or knowledge when they visit a compromised or malicious webpage. This type of attack typically exploits vulnerabilities in the user's browser or any plugins, allowing malware to be installed seamlessly, often without any interaction from the user.

This method of attack is particularly dangerous because it can occur without the user realizing it, making it difficult to defend against. Users may simply navigate to a website that appears harmless yet hosts malicious code capable of executing a download silently in the background. Once downloaded, the malicious program may perform various harmful actions, such as stealing personal information, allowing unauthorized access to the device, or further spreading malware.

Understanding the concept of drive-by downloads is crucial in the context of information security, as it emphasizes the importance of maintaining updated software, using security features in browsers, and practicing safe browsing habits to minimize the risk of such attacks.
