What it detects

This rule detects creation of a scheduled task named MicrosoftEdgeUpdateTaskMachineMS, a masquerade that imitates the legitimate Edge updater tasks which use the Core and UA suffixes. Awaken Likho used this fake task name to persist an implant while blending in with normal Edge update activity.
