At BestCybersecurityNews, we help entrepreneurs, solopreneurs, young learners, and seniors learn more about cybersecurity.

Domain name system (DNS) hijacking is a type of cyberattack that redirects users to malicious websites without their knowledge. This can be accomplished either through malware on user computers or by hacking DNS communication.
This attack has become particularly hazardous because it’s often coupled with phishing attempts that steal login credentials for banks and other organizations. Researchers are now detecting a widespread wave of DNS hijacking attacks targeting government, telecom, and Internet entities worldwide.

Can a Man-In-The-Middle Attack Lead to DNS Hijacking?

Man-in-the-middle (MITM) attacks are eavesdropping techniques that enable malicious individuals to secretly intercept data transmitted between two parties and steal sensitive information such as usernames, passwords, credit card numbers, and account details. MiTM attacks typically take advantage of weak web-based protocols by inserting themselves into communication channels without users’ knowledge.
An attacker can accomplish this by impersonating one of the parties or employing spoofing techniques to create a fake website that mirrors the original site and collects user data. Once stolen, this data is decrypted and made intelligible for further use by the perpetrator.
Eavesdropping can occur over wired networks or Wi-Fi, and it is also possible to carry out MITM attacks using fake cellphone towers known as stingrays. These devices are commercially available on the dark web and could potentially be employed to collect private communications, money transfers, and other illicit activities.
Another MITM technique involves the theft of browser cookies from insecure websites. These contain personal information like usernames, passwords, and credit card numbers that users typically store on their browsers. An attacker can then use this data to gain access to and misuse the corresponding website.
Other methods for carrying out MITM attacks involve email hijacking and Wi-Fi eavesdropping. With email hijacking, hackers gain access to a user’s email account and monitor transactions between it and other accounts. With Wi-Fi eavesdropping, they set up an unprotected fake public Wi-Fi network without a password and connect automatically when the victim logs on.
To prevent MITM attacks, organizations should implement strong identity and access management (IAM) as well as secure remote access tools. Furthermore, they should keep their user credentials updated and complex so they are harder to crack.
Man-in-the-middle (MITM) attacks are a grave security risk that can result in identity theft, unapproved funds transfers, and fraudulent bank activity. They disrupt business operations and cause havoc for victims. To thwart an attack from occurring, organizations should implement a multi-layered approach to cyber defense that includes identity management (IAM), secure remote access, and request signatures to validate time and payload of client application requests to avoid data interceptions.

What is Cache Poisoning in DNS Hijacking?

Cache poisoning is a cyber security technique that involves sending forged DNS requests to an unprotected DNS server. Once these queries have been sent, they could direct users towards malicious websites designed to steal personal data or spread malware.
DNS cache poisoning attacks can be conducted using several methods. One such technique involves loading fake Internet domain address records into a DNS server’s cache with a recursive DNS query. Once these malicious records have been loaded, any subsequent requests for these domains will be redirected to the attacker’s illegitimate servers.
One method of DNS cache poisoning involves sending thousands of fake DNS queries to a single recursive name server. In this attack, the attacker sends thousands of forged records to this recursive name server, which then stores and redirects any subsequent queries for these domains to the malicious servers.
The problem with this type of poisoning is that it’s difficult to detect even with real-time monitoring. Therefore, the damage from such an attack can be substantial, particularly for websites or applications with many users or visitors.
To avoid DNS poisoning, companies or organizations should implement DNS Security Extensions (DNSSEC). This protocol enforces a hierarchical digital signing policy at various DNS lookup levels to thwart this issue from occurring.
Additionally, companies should implement end-to-end encryption. This helps keep hackers at bay by preventing them from inserting malicious information into the DNS system.
Finally, companies should also implement firewalls and other security measures to safeguard their network against attacks. These could include anti-virus software, intrusion prevention systems, and more.
A successful cybersecurity strategy should include an exhaustive assessment of all systems and devices to detect any vulnerabilities that could allow an attacker to gain access to the network. Doing this gives companies insight into what needs to be done to prevent DNS poisoning attacks from occurring in the first place.
Companies should regularly flush the DNS cache, particularly after any changes have been made to network or equipment settings. This process can usually be accomplished by restarting the device, activating airplane mode, or using a native browser’s flush option.

What Are the Risks of DNS Spoofing?

Domain name system (DNS) spoofing is an increasingly widespread cyber attack that can have numerous detrimental effects, such as exposing confidential information or damaging network security. It offers attackers a convenient means of stealing data, spreading malware, invading networks, and even launching ransomware attacks.
Spoofing involves the use of both high-tech and low-tech tactics to entice users into divulging sensitive information or taking an action that allows them to engage in malicious activity. Common techniques include caller ID spoofing, website spoofing, and email spoofing.
Spoofing can only be successful if the attacker creates a pretext that is plausible and within the victim’s comfort level. This may involve asking an authority for help or demanding urgent action, but it must be done so that users feel compelled to act now.
Spoofing is often employed in phishing attacks, where hackers send fake emails from known or trusted companies to collect sensitive information. It may also take place as part of social engineering tactics when hackers pose as people the victim believes to be trustworthy.
Attackers use a range of methods to spoof victims’ information and systems, from basic DNS changes to intricate technical attacks involving IP addresses and ARP servers. These spoofing tactics have the potential to damage a company’s reputation, expose confidential data, and hinder growth within businesses.
DNS spoofing attacks involve the use of malware on a website to intercept traffic and redirect it to an impostor server. This can occur either locally, where the malware is installed on the victim’s computer, or remotely when spoofing is conducted from a third party’s network.
The perpetrators then create a site that looks similar to the target site and use their malware to collect sensitive information from unaware users. This is often used for gathering login and password info or gaining access to a bank account.

What are the Risks of DNS Hijacking?

DNS hijacking, also referred to as domain name server redirection, is a form of cyberattack in which hackers redirect users to malicious websites without their knowledge. It can pose serious problems for websites and businesses alike when users are unable to access the content they were expecting to view.
Hacking a DNS server can be done in several ways. For instance, hijackers may use it for pharming (displaying advertisements to users for financial gain) or phishing (redirecting users to an unauthentic version of your website with the purpose of stealing data or login information).
Additionally, some Internet Service Providers and governments utilize domain hijacking to censor or redirect their residents’ DNS queries. This is particularly advantageous in countries with strict laws that aim to stop citizens from accessing certain websites or content.
This attack works by infiltrating DNS servers and inserting a false IP address into records stored there. Once attackers have gained control over these servers, they can redirect users to malicious websites intended to steal personal information or infect them with malware.
DNS hijacking attacks are an expensive and complex threat to businesses. They can lead to lost traffic, erosion of customer trust, and reputational harm.
Despite our best efforts to prevent cybersecurity attacks, hackers continue to develop new methods for targeting vulnerable DNS settings. The CD Projekt Red ransomware attack serves as a prime example of just how detrimental a DNS hijacking attack can be for businesses.
Though these attacks can be hard to spot, it’s essential that you educate yourself on them and take proactive measures to avoid them. For example, installing antivirus software on your computer will protect it from potential attacks, as well as changing passwords regularly.
Another way to prevent DNS hijacking is by employing firewalls and other security measures to block access to DNS name servers. You should also change your router’s password in order to protect it from hackers.
Finally, it is recommended to regularly update your antivirus software and other security measures. Furthermore, enrolling in cybersecurity training is a wise idea so that you can become more knowledgeable about the threats posed to your computer and network.
