Teams from the IT and Network Operations Center (NOC) must realize that attacks from the Domain Name System (DNS) will become quite common. Financial services, telecoms, e-commerce firms, and government agencies will be most affected by a complex DNS security threat environment due to business disruption, information, and data breaches.
With the rising shift towards a more virtual workforce, few cybersecurity experts need to be told that DNS hijacking is a critical problem, one that is vital to protecting the financial assets and credibility of a business. Companies invest more than ever in implementing solutions for DNS monitoring and recruiting or honing the talent required for a good first line of defense. The various forms of DNS hijacking attacks, the costs and impacts of such attacks, and how businesses can recognize and avoid possible DNS attacks are discussed in this article.Â
In this article, we will exploreÂ
Domain Name Server hijacking or DNS hijacking, often referred to as DNS redirect, is a form of DNS hijacking attack that incorrectly resolves DNS queries to redirect users to malicious sites unexpectedly.Â
It is possible to use DNS hijacking for pharming (in this case, attackers usually display unwanted advertising to generate revenue) or phishing (displaying fake versions of sites users access and stealing data or credentials).
A sort of DNS hijacking is often used by many Internet Service Providers (ISPs) to take over DNS requests from a customer, collect data, and return advertising when users visit an unknown domain. DNS hijacking is used by some governments for censorship, redirecting users to government-authorized sites.
For a variety of purposes, a DNS could be hacked. It may be used for pharming by the hijacker, which is to show advertising revenue generation or phishing to customers, which guides users to a bogus version of your website to steal data or login information.
It is also known that Internet Service Providers (ISP) use domain redirection to monitor DNS queries from users to gather user data. Domain hijacking is used for censorship or redirecting users to alternate websites by other organizations.
To prevent DNS hijacking, there are various precautionary measures you can take to improve your DNS security. Of the basic mitigation steps, we have three categories:
Cybercriminals attack DNS routers and reconfigure them to funnel traffic on the Internet to malicious places. The DNS name server is a valuable resource that should have powerful security measures to prevent hackers from hacking website users and launching attacks. Below are the elaborate steps that can be taken by the IT team to enhance the security of the name server of your domain.
DNS hijackers also target user information and passwords, in addition to advertising items for hijacked traffic. Users of the website can prevent hijacking by changing their passwords frequently, installing and upgrading their anti-virus computers, and using secure virtual private networks.Â
Your IT team should take the following precautions to prevent DNS hijacking if your company uses a Domain Name Registrar:
Resolving domain names into numerical IP addresses, from the endpoint to the root DNS server, is rife with vulnerabilities for ordinary users and companies, thereby providing attackers with great opportunities. An attacker can redirect the web traffic of your company to the attacker-controlled networks with a successful hijack, complete with legitimate encryption certificates, and execute man-in-the-middle attacks. By modifying local DNS settings or poisoning the local host file, DNS attacks on the system are easily achieved.
In recent times, it is quite clear that information is the most powerful weapon. Therefore the security of that information should be made our top priority. Being one of the topmost preferred skills, a certification in cybersecurity would open up umpteen opportunities.
