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	`call` corpus 7 (sigma 7) `create` corpus 8 (sigma 8) `process` corpus 3 (sigma 3)
`Image`	ends_with	`\WMIC.exe` corpus 12 (sigma 12)
`OriginalFileName`	eq	`wmic.exe` corpus 33 (sigma 33)
