Everything You Need to Know About DNS AttacksIt's important to understand DNS, potential attacks against it, and the tools and techniques required to defend DNS infrastructure. This report answers all the questions you were afraid to ask.
Domain Name Service (DNS) is a critical part of any organization's digital infrastructure, but it's also one of the least understood. DNS is designed to be invisible to business professionals, IT stakeholders, and many security professionals, but DNS's threat surface is large and widely targeted.
Attackers are causing a great deal of damage with an array of attacks such as denial of service, DNS cache poisoning, DNS hijackin, DNS tunneling, and DNS dangling. They are using DNS infrastructure to take control of inbound and outbound communications and preventing users from accessing the applications they are looking for. To stop attacks on DNS, security teams need to shore up the organization's security hygiene around DNS infrastructure, implement controls such as DNSSEC, and monitor DNS traffic

The good news is you can reference the list of URLs used in the attack and immediately guard against access to these sites, at least. While updated versions of the trojan may point to other domains, it's a start. Additionally they provide a comprehensive file list that can be used for system scans of malicious files.
Because this SQL injection attack will have been patched against already in a hotfix, the biggest issue currently is the Sophos user base that does not have automatic updates enabled. Opening themselves up to the Asnarok attackers will not only provide access to data for as long as their Sophos installs remain unpatched, they offer a testbed for modifications to the code that could allow bypassing any changes made in the hotfix.
