* [Deprecated Rule] Potential Privilege Escalation via Local Kerberos Relay over LDAP
FPs in certain cases with no room for tuning.
* Update privilege_escalation_krbrelayup_suspicious_logon.toml
Co-authored-by: Colson Wilhoit <48036388+DefSecSentinel@users.noreply.github.com>
(cherry picked from commit 8d34416049)
* [Rule Tuning] Remotely Started Services via RPC
excluding noisy FPs by process.executable to be compatible with winlog and endpoint
* Update lateral_movement_remote_services.toml
Co-authored-by: Colson Wilhoit <48036388+DefSecSentinel@users.noreply.github.com>
(cherry picked from commit 6f69695820)
* [Rule Tuning] Potential Remote Credential Access via Registry
Excluding some noisy FPs by file.path (user and machine hives std paths) and event.action (scoped to logged-in)
* Update credential_access_remote_sam_secretsdump.toml
(cherry picked from commit 049fbf7979)
* [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
