Can the DNS server you use be dangerous?

Yes. They can be extremely dangerous.

Each year, the number and scale of DDoS, Dos or DNS poisoning attacks grows.

The DoS Denial of Service) attacks overload the servers with redundant data. This way, DNS servers stop responding and connecting to devices.

The DDoS Distributed Denial of Service) attacks consist in attacking servers or systems from several devices at the same time. Usually, these devices are computers infected with bots or Trojan viruses. DDoS attack flood server with redundant connection attempts, disturbing the traffic and making it impossible to use the server resources.

There is also a risk of cache poisoning of DNS servers. Cache poisoning of DNS servers is a phishing attack, which allows cybercriminals to steal sensitive data, modify the server connections and direct users to fake websites.

A simple takeover of a DNS server by malware is also a popular attack. Smilarly to cache poisoning, it leads to data theft and redirects users to phishing websites.

DNS servers are being attacked all the time. One of the biggest cyberattacks took place when the DNS server address of over a million routers was changed, which affected the following companies, among others: D-Link, Huawei, TP-Link, 3Com, Intelbras and MikroTiK. The attack took place at the end of 2018, taking a huge toll mainly on the servers in Brazil.

In Poland, there was also an infamous attack of the DNS servers provided by Orange back in 2014, which affected up to one million Internet users of this operator. The changed fake DNS server addresses included: 62.113.218.106, 5.135.199.20, 194.44.49.48.
