Internet Security

Attackers will often hijack the domain name system either on your computer or the website you intended to visit.

To access sites on the internet, computers use Domain Name Servers (DNS) to translate addresses into numbers, another area of vulnerability for intruders to violate your network. Attackers have been known to breach insecure DNS servers and tap into security holes within the Domain Name System. There are a variety of cyberattacks that can be used on vulnerable servers and DNS caches.

How is my system vulernable?

DNS cache poisoning and DNS spoofing are good examples. DNS cache poisoning tricks servers into connecting to malicious sites. For instance Let’s say you want to go to PayPal, when your cache has been poisoned you will be sent to a fraudulent PayPal site, where sensitive data and personal financial information are entered and then stolen. This scam is also known as DNS spoofing, you’ve now been led to a “spoofed” site as your cache has been “poisoned.”
