Deploy Backup and Business Continuity Recovery
If there is a crypto-ransomware infection, then the only recourse is to recover data and minimize business downtime. There are now many automated on-premise and cloud-based backup and continuity solutions that will back up data and create an air gap to stop ransomware from infecting networked drives. Business continuity also means minimal downtime and businesses can quickly return to normal.
Disable Macros and Autorun
Lots of crypto-ransomware infect systems using macros. Macros can easily be disabled in the Trust Center of every version of Microsoft® Office. It is also possible to enable individual macros, should they be used for a particular task.
While autorun is a useful feature, it is often used by malware to propagate. For instance, USB sticks will use autorun to proliferate, as do commonly used by Visual Basic Script (VBS) malware and worms. It is best to Policy disable autorun.
Ask your IT vendor if these procedures have been done.
