Ransomware - Quick Itemised Help List

May 31, 2017

Below are some ways to protect yourself and your organisation.  Some of these recommendations can be implemented immediately to reduce any upcoming attack along with a more long term future proof solution(s). One being Sophos Intercept X - if you already have Intercept X you are protected.

 

Server Access and Systems

  • Appropriate fire-walled access to your servers

  • System Backups and Disaster Recovery plan in place (tested and documented)

End Points

  • Advise users to be vigilant and do not open any suspicious email or attachments – if in doubt call the help desk

  • Ensure your users are saving their data to areas where it will be backed up – away from laptops where the single point of failure is the disk

  • Patch early and patch often to reduce the risk.

  • Execution – disable any non-used apps, for example PowerShell, macros, wscript, js, hta

    • By reducing the amount of applications, there is less chance of malformed code being executed as a memory drop.

Email Gateway

  • If possible – check if you can block, for example HTA and Java, system config files and exe’s to reduce the attack vector

  • Sophos Intercept X is a fully functioning Anti-Ransomware solution
