There was a problem hiding this comment.
I'd prefer either single rules per tool or we group them for the threat report in a emerging thread rule. As I prefer them as general rules, better split them. It's not like we find a nicer umbrella term like "sysinternal tools"/"network utulities"/...
The other solution would be to merge all existing rules for renamed system binaries into this rule but I prefer single rules for the "Renamed" stanza.
I know it's tedious but imo it's better in the long run. (better meta data and maintainability)
