DNS Security 101: Safeguarding your business from cyber threats

"Cybercrime continues to make headlines, with major brands and institutions recently forced to suspend online operations in the wake of attacks. Bad actors can exploit the Domain Name System (DNS) in schemes like phishing and ransomware, using fraudulent or lookalike domains to deceive consumers and carry out malicious activity."

"The DNS is the backbone of the internet and enables everything from website access to email and other forms of digital communication. Securing the DNS is critical to protecting the digital infrastructure we depend on. Yet, a recent revealed that 72% of companies have implemented fewer than half of the recommended DNS security measures."

"When attackers target a domain, their objective is often to deceive individuals into revealing sensitive information through tactics such as phishing or spoofing. Two prevalent forms of DNS-related cybercrime include: Domain hijacking - An unauthorized party gains control of a domain by altering its DNS records, often by exploiting weak credentials or tricking a registrar into transferring ownership. Subdomain hijacking - Cybercriminals seize control of legitimate but abandoned or overlooked subdomains, enabling them to exploit trusted brand identities to distribute malware or conduct phishing campaigns."

Cybercrime increasingly disrupts major brands and institutions, forcing suspensions of online operations and exploiting the Domain Name System (DNS) through phishing, ransomware, and lookalike domains. The DNS enables website access, email, and digital communication, making its security critical to digital infrastructure. Most companies have implemented fewer than half of recommended DNS security measures, creating wide vulnerabilities. Cybercriminals exploit underestimated digital footprints to launch phishing campaigns, distribute malware, and hijack domains or subdomains. Domain hijacking involves unauthorized control by altering DNS records or tricking registrars. Subdomain hijacking seizes abandoned subdomains to leverage trusted brands for malicious activity. Strengthening DNS defenses is essential.
