WannaCrypt Malware

Of course you have heard about the new malware, which yesterday created a lot of problems in industry. Unfortunately it is not an unknown problem.
Microsoft released a patch for this type of vulnerability already in March, but it seems once again that administrators are not patching their systems.
So, if you haven’t patched your systems at least every month, if you haven’t patched your system from March, is time to do it. And don’t forget to have a good defense system (antivirus and other prevention mechanisms). Update them to!
You can find additional information in this link.

Here is a link to post how was neutralized and who did this.
Anyway, we have already a version 2.0; you can read about this version here.
Again, please patch your systems! This update will solve a vulnerability. And don’t forget: this is not the first malware who was written on known vulnerability – patch your systems constantly!
Additionally, please disable SMB1 protocol – it is not new that it is not secure. Here and here are some guidelines how to do it via GPO.
