DNS traffic is the queries and responses between devices and DNS servers. When a user clicks on a link or types a domain name into a browser, the user’s device searches for the corresponding IP address by sending a DNS request or query to DNS servers. Recursive DNS servers initially recei...
DNS spoofing/cache poisoning:This is an attack where forged DNS data is introduced into a DNS resolver’s cache, resulting in the resolver returning an incorrectIP addressfor a domain. Instead of going to the correct website, traffic can be diverted to a malicious machine or anywhere else the...
DNS tunneling is a hacking technique that hides malware inside normal-looking DNS traffic. Since firewalls usually let DNS traffic through, attackers can use this tactic sneak in and steal data or control infected computers. It's like smuggling contraband inside a perfectly normal-looking package. ...
The primary benefit of using DoH is that encrypting DNS name resolution traffic hides online activities. When users enter a URL into their browser, a DNS query is typically needed to resolve the domain portion of the URL into an IP address. While it may be tempting to think of this name ...
DNS spoofing is the resulting threat which mimics legitimate server destinations to redirect a domain’s traffic. Unsuspecting victims end up on malicious websites, which is the goal that results from various methods of DNS spoofing attacks. DNS cache poisoning is a user-end method of DNS spoofin...
DNS spoofing is an attack that uses altered Domain Name records to redirect traffic to a fraudulent site. Learn how attacks take place and how to secure your DNS records
A DNS leak is a security flaw that occurs when requests are sent to an ISP's DNS servers even when a VPN is being used to protect users. A VPN is designed to encrypt a user’s internet connection, which keeps their traffic in a private tunnel that hides all of their browsing activity...
DNS is widely trusted by organizations, and DNS traffic is typically allowed to pass freely through network firewalls. However, it is commonly attacked and abused by cybercriminals. As a result, the security of DNS is a critical component of network security....
DNS spoofing is an attack in which traffic is redirected from a legitimate website such as www.google.com, to a malicious website such as google.attacker.com. DNS spoofing can be achieved by DNS redirection. For example, attackers can compromise a DNS server, and in this way “spoof” ...
With HTTPS, traffic is encrypted such that even if the packets are sniffed or otherwise intercepted, they will come across as nonsensical characters. Let’s look at an example: Before encryption: This is a string of text that is completely readable ...
