Employees attempting to access corporate systems over DNS Spoofing Examples home and public. WiFi networks when the COVID-19 pandemic has forced millions of employees to work remotely. It has caused a rapid increase in the volume of DNS queries. This has led to a marked increase in the number of cyberattacks targeting DNS. Some of these attacks, which used traditional methods such as “tunneling. Also took advantage of newly discovered vulnerabilities such as the vulnerability in Windows DNS. Which was in effect for seventeen years before being discovered in July 2020.
which began to revive with the Colombia Phone Numbers newly discovered SAD DNS attack last year, have been largely stopped by modern defense measures such as DANE and DNSSEC. However, since these DNS security methods are not implemented by everyone, such attacks still continue.
Other notable DNS poisoning attacks in recent years include attacks on AWS and Malaysia Airlines:
DNS cache poisoning attacks
A DNS spoofing attack on Amazon Web Services (AWS) in 2018 resulted in the theft of $17 million worth of Ethereum. The thieves diverted traffic from those trying to log into their accounts to a fake website to get their login information, and used this information to access users’ accounts and steal their money.
In 2015, a hacker group known as the Lizard Squad carried out a DNS poisoning attack on Malaysia Airlines. The attack, which redirected the site’s visitors to a fake website that encouraged them to log in, resulted in serious losses for the airline, which had a tough year with two lost flights.
Ways to Avoid DNS Cache Poisoning
DNS poisoning attacks are very dangerous as they can be difficult to detect and resolve. DNS service provider or website owners should take steps to protect users by using various tools and protocols to manage threats. Here are some of the best-known ways to protect yourself from this type of attack:
Introducing DNSSEC is one of the most valuable measures you can take to guard against DNS poisoning attacks. DNSSEC relies on public key cryptography to make it possible to validate DNS data that is not standard in existing internet protocols.
Another important step is to always encrypt the data contained in DNS requests and responses. This offers an additional layer of protection against cybercriminals that may interfere with data. For example, even if an attacker manages to get hold of the encrypted data, he cannot read it to get the information he needs to replicate for future responses.
