Alright !!! For those people who say “Use Linux to avoid such attacks” YES ! You are correct. You rarely see malware on Linux / MacOS, but its not necessary and you have to tighten the security.. Most desktop computers use windows so that is more profitable for hackers . 

Here are precautions you can take against any type of Ransomware attack:

  • Disable RDP (Remote Desktop Connection) – If you are in network and suspect that you are a victim of such attack then disable RDP Protocol. Malware often accesses target machines using RDC. Refer this link to disable it – https://technet.microsoft.com/en-us/library/cc731588(v=ws.11).aspx
  • Don’t enable macros in document attachments received via email. Many ransomware attacks arrive in documents (embedded document scripts).  Microsoft deliberately turned off auto-execution of macros by default as a security measure.
  • Preview any email attachment before downloading it. Ignore unsolicited attachments.
  • Below are some of the sample subject lines of Ransomware Virus Mail. It is recommended not to open such emails. Such emails are likely to contain virus or malicious programs which encrypts/destroys files in computer or locks the computer and asks for Digital Ransom to return the control of files/computer:

  • Patch Early. Microsoft provides patches often. For Windows 10 you must be getting patch almost every other day or every week. Malware often relies on security bugs in popular applications such as default browsers, office applications.
  • If you feel that you opened the malicious file then quickly disconnect the network. Use System Restore to get windows back on previous state. https://www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/
