What is DNS?
DNS, short for Domain Name System, is the process of converting URLs like www.google.com to IP addresses so computers know where to take you. Think of IP addresses like addresses, without an address how would you know where someone's house is? DNS Hijacking is the process of intercepting the request and replying for the DNS server to point you to the wrong place.
How does DNS Hijacking work?
DNS hijacking is very dangerous as the end user won't know its happening, as its all done in the background. Imagine wanting to go to amazon.com and being redirected to a fake amazon page. A bad actor could use this fake page to steal your amazon credentials as you might not know the page is fake. DNS hijacking is becoming more common as its an easy way to obtain information willingly from users as they wont even know what's happening. This can also lead to more advanced attacks like DNS cache poisoning, ransomware or back doors into your machine.
What can I do?
DNS hijacking is usually setup through malware and other forms of malicious code. These can be prevented by ensuring your Anti Virus and Anti malware applications are up to date. You can also be proactive by not opening suspicious emails attachments, or links. If you visit a page and it seems suspicious its better to close it and not enter any information. A dead giveaway is usually broken links or pictures and bad grammar. You can also check that the page is secure by reviewing its certificate.
