+description: |-
+    The following analytic detects the use of macOS AppleScript utilities to execute shell commands or compile AppleScript containing shell-command logic.
+    The analytic identifies `osascript` invocations using AppleScript's `do shell script` command, which executes shell commands on the host.
+    It also identifies `osacompile` invocations referencing `do shell script`. `osacompile` compiles AppleScript into a compiled script but does not execute it directly.
+    Adversaries may abuse these utilities to execute shell commands, stage AppleScript payloads, or prepare scripts for later execution. Matches involving `osacompile` should be interpreted as script compilation or staging rather than confirmed shell-command execution.

+how_to_implement: |-
+    This detection uses osquery and endpoint security on MacOS. Follow the link in references, which describes how to setup process auditing in MacOS with endpoint security and osquery.
+    Also the TA-OSquery (https://splunkbase.splunk.com/app/8574) must be deployed in order to have the osquery data populate the data models.
+known_false_positives: |-
+    Legitimate administrative scripts or automation tools using Applescript.
