Stages and Predicates

Stage 0: `condition`

all of selection_* and not 1 of filter_main_*

Stage 1: `selection_img`

selection_img:
    - Image|endswith: '\wmic.exe'
    - OriginalFileName: 'wmic.exe'

Stage 2: `selection_cli`

selection_cli:
    CommandLine|contains: 'Product'

Stage 3: `not filter_main_*`

filter_main_call_operations:
    CommandLine|contains:
        - ' uninstall'
        - ' install'
filter_main_csproduct:
    CommandLine|contains: 'csproduct'

Exclusions

The rule actively suppresses these predicates.

Field	Kind	Excluded values	Search
`CommandLine`	match	`install`	`excludes:CommandLine` `field:"CommandLine" value:" install"`
`CommandLine`	match	`uninstall`	`excludes:CommandLine` `field:"CommandLine" value:" uninstall"`
`CommandLine`	match	`csproduct`	`excludes:CommandLine` `field:"CommandLine" value:"csproduct"`

Indicators

These rows show field, operator, and value matches.

Field	Kind	Values	Search
`CommandLine`	match	`Product` corpus 2 (sigma 2)	`field:"CommandLine" kind:match value:"Product"`
`Image`	ends_with	`\wmic.exe` corpus 62 (sigma 62)	`field:"Image" kind:ends_with value:"\wmic.exe"`
`OriginalFileName`	eq	`wmic.exe` corpus 80 (sigma 38, elastic 24, splunk 18)	`field:"OriginalFileName" kind:eq value:"wmic.exe"`
