+name: UAC bypass via elevated Internet Explorer add-on installer COM interface
+id: 340b09e5-6149-4655-998c-1c2fe0041576
+version: 1.0.0
+description: |
+  Identifies potential User Account Control (UAC) bypass activity involving the
+  elevated Internet Explorer add-on installation mechanism exposed through a
+  COM interface. Adversaries can take advantage of scenarios in which legacy
+  Internet Explorer components are abused to execute code with high integrity
+  outside of standard user consent flows.
