Someone could be using your domain right now and you would not know

Short summary

8,000+ domains were hijacked via abandoned DNS records (SubdoMailing campaign), sending 5 million fraudulent emails daily undetected. The same technique compromised the CDC, CoW Swap, and a Russian military operation, often going unnoticed for weeks or months. DNS/WHOIS monitoring—tracking record changes, registration data, and dangling CNAME entries—is the practical defense, but most organizations don't monitor because registrars don't.

• •SubdoMailing hijacked 8,000+ domains through dangling DNS records pointing to abandoned cloud resources
• •CDC, major brands, crypto exchanges, and government systems exploited via same technique; detection delayed weeks or months
• •Solution: monitor DNS (A, AAAA, MX, NS, TXT, CNAME, SOA, CAA records), WHOIS data, and scan for dangling entries
