Client-Side Attack: An attack that targets vulnerabilities in client software that interacts with a compromised server or processes malicious data. Common examples include attacking a user’s web browser via malicious web pages, email clients via phishing emails, or software applications via malicious data files. These attacks often rely on the execution of malicious scripts or the exploitation of vulnerabilities in the client software. The aim is often to gain unauthorized access, steal sensitive data, or establish a persistent presence on the victim’s system.
