How email in transit can be intercepted using DNS hijacking?

Email is one of the most popular methods of communication, but it's also one of the most vulnerable. Your email messages are stored on servers all over the world, and they pass through a complex network of computers before reaching their destination. This makes email an easy target for hackers.

One of the most common ways for hackers to intercept email is by DNS hijacking. DNS is the system that converts domain names (like www.example.com) into IP addresses (like 192.0.2.1). When you send an email, your computer looks up the IP address of the recipient's server using DNS.

If a hacker can hijack the DNS system, they can redirect your email to their own server. From there, they can read your messages, or even send messages in your name. DNS hijacking is a serious security threat, and it's important to be aware of the risks.

There are a few things you can do to protect yourself from DNS hijacking. First, make sure you're using a secure DNS service. Second, keep your DNS settings up to date. And finally, be careful when clicking on links in email messages. If you're not sure where a link is taking you, don't click it.
