When constructing the query packet, DNS lookup removes the first part of the domain name (the client host name) and replaces it with wpad. Then, it "moves up" in the hierarchy by removing more parts of the domain name, until it finds a WPAD PAC file or leaves the current organisation. The browser guesses where the organisation boundaries are.
The threat involves using a PAC, discovered automatically by the system, to redirect the victim's browser traffic to an attacker-controlled server instead. Another issue with pac-file is that the typical implementation involve clear text http retrieval, which does not include any security features such as code signing or web certificates.
A reverse DNS lookup is a query of the DNS for domain names when the IP address is known. Multiple domain names may be associated with an IP address. The DNS stores IP addresses in the form of domain names as specially formatted names in pointer (PTR) records within the infrastructure top-level domain arpa. For IPv4, the domain is in-addr.arpa.
OpenDNS is an American company providing Domain Name System (DNS) resolution services—with features such as phishing protection, optional content filtering, and DNS lookup in its DNS servers—and a cloud computing security product suite, Umbrella, designed to protect enterprise customers from malware, botnets, phishing, and targeted online attacks.
For example, to do a reverse lookup of the IP address 8.8.4.4 the PTR record for the domain name 4.4.8.8.in-addr.arpa would be looked up, and found to point to dns.google. If the A record for dns.google in turn pointed back to 8.8.4.4 then it would be said to be forward-confirmed.
