DNS hijacking (also known as DNS redirection or DNS poisoning) is a type of cyber attack that involves manipulating the Domain Name System (DNS) to redirect users to fraudulent websites or steal sensitive information (such as usernames and passwords).
DNS is a hierarchical decentralized naming system that translates human-readable domain names (such as www.example.com) into IP addresses (such as 192.0.2.1) that computers can understand. When a user types a domain name into their web browser, the DNS server responsible for that domain is queried to find the IP address associated with it. Then, the user is directed to the corresponding website.
DNS hijacking works by compromising the DNS server or the user's computer to redirect DNS queries to a different server controlled by the attacker. For example, if an attacker gains access to a DNS server, they can modify the DNS records for a specific domain to point to a different IP address. This can be done by either changing the existing DNS records or creating new ones that override the legitimate ones. When a user types in the domain name, the malicious DNS server responds with the attacker-controlled IP address, which can be used to direct the user to a fake website that looks identical to the legitimate one.
DNS hijacking can also be carried out by infecting the user's computer with malware that modifies the DNS settings. This can be done through phishing emails or exploiting vulnerabilities in the user's browser or operating system. Once the DNS settings are modified, the user is directed to the attacker's website whenever they attempt to access the legitimate site.
The consequences of DNS hijacking can be severe. Attackers can use fake websites to steal login credentials or sensitive data (such as credit card numbers). They can also use the hijacked DNS server to launch additional attacks (such as malware downloads or phishing scams).
