+  1. Filter CrowdStrike events
+
+  #Vendor ="crowdstrike"
+
+
+  Restricts the search to logs ingested from CrowdStrike.
+
+  2. Filter for brute-force detection events
+
+  "#event_simpleName" ="RemoteBruteForceDetectInfo"
+
+  Returns only events generated by CrowdStrike's brute-force detection logic. These events indicate that CrowdStrike identified suspicious authentication activity consistent with a brute-force attack.
+
+  3. Filter for successful brute-force compromises
+
+  DetectDescription=~/^A public IP successfully brute forced an account on this system/
+
+  Uses a regular expression to match detection descriptions beginning with:
+
+  A public IP successfully brute forced an account on this system
+
+  This is the most important filter because it narrows the results to cases where:
+
+  The source was a publicly routable IP address.
+  The brute-force attack was successful.
+  An account on the endpoint was successfully authenticated after repeated login attempts.
