Using OPENDNS on a Mikrotik

At the office we use a Mikrotik which is connected via fibre to Cool Ideas. We use OpenDNS as a Information Security tool. It prevents ransomware and bots from becoming major incidents within the office.

The router is scheduled to do a daily update via script of the OpenDNS settings. Below is the example:

:local opendnsuser "user@domain.co.za";
:local opendnspass "itsprivate";
:local opendnshost "office";

:log info "OpenDNS Update";
:local url "https://updates.opendns.com/nic/update";
/tool fetch url=($url . "\3Fhostname=$opendnshost") user=("$opendnsuser") password=("$opendnspass") mode=https dst-path=opendnsupdate.txt
:local opendnsresult [/file get opendnsupdate.txt contents];
:log info "OpenDNS: Host $opendnshost - $opendnsresult";

In the early minutes of the attack, we worked with our Talos counterparts to analyse the behaviour of WannaCry and protect our customers. We were also particularly proud to see that our Investigate product helped MalwareTech reduce WannaCry’s impact. In this post, we hope to give you a retrospective analysis of what we’ve observed during the first critical hours of the event.
