DNS: WPAD Registration Query
This signature detects attempts to register WPAD to the DNS server. This could indicate a possible "Man in the Middle" attack. An attacker could control the DNS server to forward users to a machine that they control.
Extended Description
The Microsoft Windows DNS Server is prone to an access-validation vulnerability because the software fails to properly restrict access when defining WPAD (Web Proxy Autodiscovery Protocol) entries.
An authenticated attacker may exploit this issue to create a WPAD DNS entry. This may aid in man-in-the-middle and spoofing attacks. Other attacks are also possible.
