A few hours ago new variants of the WannaCry ransomware started emerging. One of the variants was also stopped today by registering a kill switch domain, the same way the ransomware was stopped on Friday. A second variant is not encrypting infected machines due to an error in programming, but it is spreading. We expect new variants to emerge all week that continue to exploit the vulnerability in SMB that WannaCry has been using. It is critical that Windows users protect themselves immediately against this.
Here is an excellent article with some useful and interesting information.
It is thorough in its recommendations , however as a minimum you should aim for :
- All windows updates installed and up to date
- Antivirus software installed, active and virus patterns up to date
- Extreme caution opening email attachments
- All data backed up to more than one location, and if an external drive is used, that at least one is kept offline i.e. not connected to the computer system.
