WannaCry: Protect Yourself

Edit



WannaCry is the ransomware de jour that has wreaked complete havoc globally over the course of this past weekend and may continue into the coming week.

 Spain's National Cryptological Centre has released a vaccine for the devastating ransomware:
This tool is available to all organisations that need to use it. It creates a mutex (mutual exclusion algorithm) on the computer that prevents the execution of the malicious code WannaCry 2.0. It is important to note that this tool is Not intended to clean compromised machines.

 CCN-CERT indicates that the tool should be run after each restart. This process can be automated by modifying the Windows registry or through the implementation of the proper policies in the domain

 This tool works on all versions of Windows.

 CCN-CERT NoMoreCry Tool is located in CCN-CERT's cloud, LORETO. In this location there is also available a complementary Script that prevents the execution of the malware on Windows computers in English and Spanish.
