As an increasing number of organizations operate online, cybercriminals are finding new ways to exploit weaknesses in online infrastructure to carry out their attacks. One of the most insidious attacks that businesses face is domain hijacking. In this article, we explore the dangers of domain hijacking, the methods used by attackers, and how businesses can protect themselves from this threat.
What is Domain Hijacking?
Domain hijacking is a form of attack in which an attacker gains control of a company’s domain name resources and redirects user traffic to attacker-controlled infrastructure. This enables the attacker to obtain valid encryption certificates for the domain, allowing for man-in-the-middle attacks.
Attackers can achieve domain hijacking through a fraudulent registrar transfer request or by making false changes to the domain registration. Once the attacker gains control of the domain, they can redirect traffic to malicious websites, effectively stealing visitors and revenue from the legitimate domain owner.
DNS Attack Vectors
There are several ways that cybercriminals can carry out a domain hijacking attack. Here are four of the most common methods:
Router DNS Hijack
In a router DNS hijack, the attacker takes advantage of weak default passwords or firmware vulnerabilities to gain control of the domain service provider’s router. Once in control, the attacker can reconfigure the DNS settings to redirect traffic to malicious websites.
Man-In-The-Middle DNS Hijacking
In a man-in-the-middle DNS hijack, the attacker intercepts the communication between a website’s traffic and its DNS server. The attacker then alters the DNS settings to direct traffic to a malicious IP address.
Local DNS Hijack
In a local DNS hijack, the attacker installs malware on a website user’s computer. The malware gives the attacker access to the user’s network systems, enabling them to steal data and change DNS settings to direct the user to malicious websites.
Rogue DNS Server
In a rogue DNS server hijack, the attacker intercepts the DNS server and alters the DNS settings to redirect traffic to fake websites.
Protecting Your Business from Domain Hijacking
Domain hijacking can have serious consequences for businesses, including lost revenue, damaged reputation, and legal liability. Here are some steps that businesses can take to protect themselves from this threat:
- Use strong passwords and two-factor authentication to protect domain registrar accounts.
- Monitor domain registration information for any unauthorized changes.
- Use a DNS security service to protect against DNS hijacking attacks.
- Implement a Domain-based Message Authentication, Reporting, and Conformance (DMARC) policy to prevent email spoofing attacks.
- Regularly back up website data and use a web application firewall to protect against website attacks.
Domain hijacking is a growing threat to businesses operating online. By understanding the methods used by cybercriminals and implementing security measures to protect against these attacks, businesses can reduce their risk of falling victim to domain hijacking. It is crucial for businesses to stay vigilant and take proactive steps to protect their online infrastructure from this and other types of cyberattacks.
