Domain Name System (DNS) poisoning can redirect you to a fake website, even when you type the correct web address. This happens when false DNS information is accepted and stored by a DNS cache, causing a device or application to load the wrong IP address for a trusted domain.
For example, you might try to visit your bank, email account, or another familiar service but be sent to a look-alike page designed to steal login details, multi-factor authentication codes, or payment information. The page may look convincing, which makes the attack harder to spot.
DNS cache poisoning is one of the more serious DNS-related threats because it can redirect you without an obvious warning. It can also be confusing. If someone doesn’t understand how DNS connects a domain name to the right website, they may assume the website itself was hacked. In some cases, the problem may be closer to home, such as a compromised router, altered DNS settings, or a poisoned local DNS cache. Security software can help block some threats linked to DNS spoofing, but it can’t prevent every DNS-level attack on its own.
When connected to CyberGhost VPN, your DNS requests are routed through CyberGhost's DNS servers inside the encrypted VPN tunnel. This can help reduce the risk of some DNS-based attacks on local networks, such as malicious DNS redirection on public Wi-Fi. However, no VPN can prevent every type of DNS attack, and additional protections such as HTTPS, DNSSEC, and good security practices remain important.
