Indicators

Each row is a field, operator, and value that the rule matches. The corpus column counts how many other rules in the catalog look for the same combination: high numbers point to widely-used, community-vetted indicators. Blank or 1 shows that the indicator is specific to this rule.

Field	Kind	Values
`CommandLine`	match	`query` corpus 6 (sigma 6) `termservice`
`Image`	ends_with	`\sc.exe` corpus 17 (sigma 17)
`OriginalFileName`	eq	`sc.exe` corpus 10 (sigma 10)
