The internet is full of infected hosts. There have been many suggestions about how to go about cleaning up the mess, the challenges are complex, and current cleanups taking longer than expected. So take, for example, the current DNSChanger cleanup. Here is a traditional profit motivated 4 million PC and Mac node malware case worked by the Fbi , finishing with a successful set of arrests and server takedown.
While victims might not commonly be seen as a part of an enterprise, leaving the 4 million DNSChanger infected hosts connected to the internet, with many failing to download Windows updates, may leave open a window of opportunity for other cybercriminals.
And even though past botnets have been partly handled by communicating with the malicious bot code itself from usurped C2 servers, those steps are being avoided again. Without this type of intervention, how is the cleanup going four months later? Not all that well, it would seem. Approximately a half million hosts of the 4 million were infected in the US and they are not being cleaned up as planned.
One ISP alone requested more time for the remaining 50k infected hosts on their networks. And the Fbi foresees enough of a problem that they requested the judge setting the original March 8th cutoff date to move the DNS server cutoff to July 9th, effectively doubling the amount of time allowed to clean up DNSChanger infected hosts. A variety of voices claim that around half of the Fortune , hundreds of businesses, and many government agencies all maintain systems that would simply not be able to resolve domain names and become unusable if the replacement DNS servers were taken down in early March.
In the command line, run the following command to list all network interface information, including configured DNS server IP addresses:.
In addition to manually looking up and checking your DNS settings, a number of Web services have popped up that will test your system for the DNSChanger malware. If these tests come up clean, then you have nothing to worry about; however, if they give you any warnings, then you can use an anti-malware scanner to check for and remove the DNSChanger malware.
Given that the malware was abruptly halted in November , there's been ample time for security companies to update their anti-malware definitions to include all variants of DNSChanger. If you have a malware scanner and have not used it recently, then be sure to launch and update it fully, followed by performing a full scan of your system. If your router or computer is not showing any valid DNS server addresses after you have removed the malware, and your system is unable to connect to Internet services, then you might try configuring your system to use a public DNS service, such as those from OpenDNS and Google, by entering the following IP addresses into your system's network settings:.
If after Monday you find you can no longer access the Internet, then it's likely your system or network router is still configured with the rogue DNS servers and you will need to again attempt to detect and remove the malware from your systems.
Luckily the malware is not viral in nature so it will not self-propagate and automatically re-infect systems. Therefore, once removed and once users have set up valid DNS servers on their systems, then the affected computers should have proper access to the Internet.
