While this is completely unrelated to any particular malware, there is a rather disconcerting DNS cache-poisoning vulnerability that has surfaced which deserves the attention of any and every organization on the planet that operates their own DNS servers.... Palo Alto Networks has a number of DNS cache poisoning signatures for specific vendors, as well as, a general brute force signature to detect this type of activity. Look at TID 40003 for the general threshold based signature and 35190, 31349, and 31123 for specific vendor DNS cache poisoning vulnerabilities.

What is DNS Poisoning? freeonlineresearchpapers.com

The DNS cache poisoning is very difficult to detect. It can last until the TTL (time to live – validity time of a request in cache) expires on the cache data or an administrator realizes it and resolves the problem. Depending on the TTL duration, servers can take some days before resolving the problem by themselves....
There are also cache poisoning tools available to help organizations prevent cache poisoning attacks. The most popular cache poisoning prevention tool is probably DNSSEC (Domain Name System Security Extension). DNSSEC is a cache poisoning tool developed by the Internet Engineering Task Force that provides secure DNS data authentication.

  • Protections built into DNS software to protect against cache poisoning include adding variability to outgoing requests, to make it harder for a hacker to get a bogus response accepted. Possible
  • DNS spoofing is known by many names such as DNS hijacking or DNS cache poisoning. In these attacks, the attacker compromises the cache of a DNS server to hijack it. When the users that are connected to the compromised DNS server try to send a DNS request, they are routed to a malicious website as set by the attacker.
