Questions and Answers:

  • How does DNS spoofing work?
    Attackers corrupt the DNS cache, causing a user’s request for a legitimate website to be redirected to a malicious site without their knowledge.

  • What are the consequences of a DNS spoofing attack?
    DNS spoofing can lead to data theft, malware infection, and unauthorized access to sensitive accounts by redirecting users to malicious websites.

  • How can organizations protect against DNS spoofing?
    Organizations can use DNSSEC (DNS Security Extensions), regularly monitor DNS servers, and educate users to verify URLs before entering sensitive information.
