Security Update: WannaCry ransomware

Hi ~okeanos users,

There is a rather dangerous ransomware, the WannaCry / Wcry / WannaCrypt ransomware, that has been spreading since Friday, May 12. The ransomware takes advantage of the MS17-010 vulnerability that affects Microsoft Operating Systems.

In order to protect the virtual machines from exposure to the WannaCry / Wcry / WannaCrypt ransomware, all incoming TCP traffic to ports 137-139 & 445 has been blocked.

The aforementioned firewall rules were applied to partially prevent the ransomware from spreading. Therefore, we urge you to perform all the necessary updates on your Windows virtual machines.

For a more thorough explanation on this subject, we suggest you read the following blog posts:

  • Stay safe,
