How to Fight It?

Bottom line: Update your software and keep a backup of your files. Lately, Microsoft released a statement asking users to get MS17-010 update installed in their computers. Additionally, it also released various fixes and patches available for out-dated versions of Windows, including Windows XP, Windows 8 and Windows Server 2003.

In addition, you can:

  • Download your data into an external hard drive or create a backup on a cloud based service.
  • Keep a straight check on your computers’ medical and credit reports regarding any deceitful activity in the past.
  • Do not open unknown mails. Get a heads-up on phishing and read a brief about the social engineering attack.
  • Keep your systems upgraded with Anti-Virus protection.
  • Block spam mails.
  • Switch on the “Disable Macros” on Microsoft Office products.

As per 16 May 2017, University College London researchers stated that their “PayBreak” system can defeat the ransomware. It has been contained up till now, but there might be a possibility that the attackers might change the codes and return. So keep your system fully secured and follow the steps to avoid such attacks.
