Safeguarding Network: Mechanisms and Prevention Strategies of DNS Hijacking

The paper examines the threat of DNS hijacking, a sophisticated cyber-attack that redirects legitimate traffic to malicious websites. It begins by explaining how the Domain Name System (DNS) works, translating human-readable domain names into machine-readable IP addresses. However, DNS hijacking exploits vulnerabilities in this process, allowing attackers to reroute users to fraudulent sites designed for criminal purposes like data theft, malware distribution, and financial fraud. The paper delves into the various techniques used in DNS hijacking, including compromising DNS servers, malvertising, and router exploitation. It discusses recent high-profile cases impacting companies and government agencies, demonstrating the serious implications for cybersecurity, privacy, and trust online. To mitigate these risks, the paper recommends strategies such as adopting secure DNS protocols, using reputable providers, applying security patches, and educating users. Building a strong cybersecurity culture is emphasized as crucial for protecting against this evolving threat to the integrity of the internet. Overall, the paper highlights the importance of understanding and defending against DNS hijacking in the digital age.
