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.
