Definition
DNS spoofing is an attack where a user is sent to the wrong IP address when they try to visit a real website. This can make a fake website appear to load from a trusted domain, even though the user has been redirected.

Why it matters
DNS spoofing matters because it can trick users into entering passwords, payment details, or personal information on a fake site. It can also be used to intercept traffic, spread malware, or disrupt access to legitimate services.

Example use case
A user types their bank’s website address into a browser, but DNS spoofing sends them to a fake login page. The page looks real, and the attacker attempts to capture the user’s credentials.
