Hundreds of subdomains across 34+ universities, including prestigious institutions like Berkeley and Columbia, are serving malicious content and pornography due to poor DNS record management—specifically the failure to remove CNAME records when subdomains are decommissioned. This security lapse exploits a common operational gap where organizations lack comprehensive subdomain inventories and regular audits, allowing threat actors to hijack expired domains and leverage university brands for search engine visibility. For IT organizations, this represents a critical governance and security risk that demands immediate attention to DNS hygiene practices and decentralized resource management.
