From 39c0efe2d5b3ddf0db3feb556a4e9e71de20dde8 Mon Sep 17 00:00:00 2001 From: Mohana Shankar D <48013681+msdlearn@users.noreply.github.com> Date: Wed, 10 Jul 2024 20:35:09 +0530 Subject: [PATCH] Update T1113.yaml (#2827) Detects the enabling of the Windows Recall feature via registry manipulation. Windows Recall can be enabled by deleting the existing "DisableAIDataAnalysis" registry value. Adversaries may enable Windows Recall as part of post-exploitation discovery and collection activities. This rule assumes that Recall is already explicitly disabled on the host, and subsequently enabled by the adversary.
