Stages and Predicates

Stage 1: `selection`

or:
ServiceFileName|contains: cachedump
ServiceFileName|contains: dumpsvc
ServiceFileName|contains: fgexec
ServiceFileName|contains: gsecdump
ServiceFileName|contains: mimidrv
ServiceFileName|contains: pwdump
ServiceFileName|contains: servpw

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
`ServiceFileName`	match	`cachedump` `dumpsvc` `fgexec` `gsecdump` `mimidrv` `pwdump` `servpw`

Neighbors

Broader alternatives (more inclusive than this rule)

These rules match a superset of what this rule catches. They cover the same events plus more. Use them if you want wider coverage and can absorb more false positives.
