What are exploit kits primarily used for?

Exploit kits are primarily used for exploiting browser vulnerabilities through malicious code. These kits are collections of software tools that attackers use to identify and exploit weaknesses in web browsers and their associated plugins. When a user unknowingly visits a compromised website, the exploit kit can deliver malware to the user's system by leveraging these vulnerabilities.

The focus of exploit kits is to automate the process of identifying vulnerabilities and deploying the necessary code to execute an attack, often with the goal of gaining unauthorized access to systems or stealing sensitive information. Their effectiveness relies on the existence of unpatched vulnerabilities in the user's software.

In contrast, creating secure software, enhancing user privacy online, and developing encryption techniques for data are not the primary purposes of exploit kits. These activities are more aligned with defensive security measures and software development best practices, rather than the malicious activities associated with exploit kits.
