Is your organization leaking sensitive Dynamic DNS data? Here’s how to find out

Wiz researchers disclosed the "Dynamic DNS Leak" at Black Hat: a DNS hosting vulnerability affecting Windows endpoints that can cause dynamic DNS traffic and sensitive internal information to leak outside corporate networks. Wiz released a free Dynamic DNS Checker to detect vulnerable domains and advises fixing SOA/Dynamic DNS configurations; AWS and Google have patched the provider issue but many customers and other DNS providers may still be exposed.
