In 2019, Surfshark launched “Surfshark Alert” & “Surfshark Search” and started their research activities, releasing the first Digital Quality of Life (DQL) index. [8] Later, in October 2019, Surfshark became one of the first ten VPN packages to receive an official seal of approval granted by an independent IT-Security Institute AV-TEST .
Surfshark B.V. is a cybersecurity company that was established in 2018. It launched its first product, a Surfshark VPN, in the same year.Currently, Surfshark offers a range of cybersecurity tools: a VPN, a data leak detection system called Surfshark Alert, a private search tool known as Surfshark Search, and an antivirus named Surfshark Antivirus.
Regular DNS leak testing is crucial for VPN users to ensure their privacy, as DNS leaks can expose browsing activity to ISPs and other third parties, even when a VPN is active. [4] DNS leaks can be addressed in a number of ways: Encrypting DNS requests with DNS over HTTPS or DNS over TLS, which prevents the requests from being seen by on-path ...
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. [1] This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards.
DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks [1] by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver. [2]
DNS over TLS (DoT) is a network security protocol for encrypting and wrapping Domain Name System (DNS) queries and answers via the Transport Layer Security (TLS) protocol. The goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data via man-in-the-middle attacks .
DNS spoofing, also referred to as DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver's cache, causing the name server to return an incorrect result record, e.g. an IP address. This results in traffic being diverted to any computer that the attacker chooses.
A fast-flux service network (FFSN) is a network infrastructure resultant of the fast-fluxed network of compromised hosts; the technique is also used by legitimate service providers such as content distribution networks (CDNs) where the dynamic IP address is converted to match the domain name of the internet host, usually for the purpose of load balancing using round-robin domain name system ...
