How to block inbound network traffic from TOR exit nodes?

Question

One of the recommendations in Steve Gibson's Security Now podcast Ep 731 to protect against the Sodinobiki ransomware is to block inbound network traffic from TOR exit nodes.

 How can I do this Sophos UTM? Have seen some old discussions here, but nothing definitive or recent. 
 Thanks, James.

Hi 
 I've also been watching 'Security Now!' for many years and after watching that programme, I used 'Application Control' to block all TOR activity from traversing any network boundaries (I don't use TOR); see below image: 
 
 I've been running UTM (with https inspection enabled) for over 3 years, but that was the first time that I'd tried the 'Application Control' feature (thus the Facebook entry to test and familiarise myself with the feature; that one certainly seems to work very well). 
 Kind regards,
