Clickjacking

A type of attack in which the victim clicks on links on a website they believe to be a known, trusted website. However, they are actually clicking on a malicious, hidden website overlaid onto the known website.

Credential Stuffing

An attack that uses stolen username and password combinations from previous data breaches to attempt logins into other services. Since many people reuse passwords, attackers run automated tools that test millions of credential pairs against target websites.

Cross-Site Scripting

An attack performed through web browsers, taking advantage of poorly-written web apps. For example, an attacker can trick a user into clicking on a specially crafted, malicious hyperlink that appears to lead to an innocent site, but the site is actually the attacker's and includes embedded scripts.

Cyber Attack

A cyberattack is a deliberate attempt by an individual or group to compromise another party’s information system. Attackers typically aim to disrupt operations or gain unauthorized access to data for personal or organizational gain.
