Description: DNS exploitation refers to the use of DNS for malicious purposes, such as data exfiltration. This phenomenon is based on the manipulation of the Domain Name System (DNS), which is fundamental for navigation on the Internet, as it translates human-readable domain names into IP addresses that computers can understand. Attackers can exploit vulnerabilities in the DNS protocol to carry out various malicious activities, such as stealing sensitive information, redirecting traffic to fraudulent sites, or creating botnets. DNS exploitation can include techniques like DNS tunneling, where data is encapsulated within DNS queries, allowing attackers to evade firewalls and other security measures. This practice is particularly concerning, as DNS traffic is often considered benign and can therefore go unnoticed by intrusion detection systems. DNS exploitation poses a significant risk to cybersecurity, as it can be used to compromise entire networks and facilitate more complex attacks, such as ransomware or data breaches.
