* [Rule Tuning] Persistence via Update Orchestrator Service Hijack
I changed the query to exclude FPs for safe executables found in telemetry: MoUsoCoreWorker.exe and OfficeC2RClient.exe. Changed the query type to KQL to account for the wildcard needed to capture 2 of the executable paths found in telemetry. I'm open to changing back to eql with suggestions.
* Update persistence_via_update_orchestrator_service_hijack.toml
revert back to eql

rules/
Rules within this folder are organized by solution or platform. The structure is flattened out, because nested file hierarchies are hard to navigate and find what you're looking for. Each directory contains several .toml files, and the primary ATT&CK tactic is included in the file name when it's relevant (i.e. windows/execution_via_compiled_html_file.toml)
