What it detects

This rule detects creation of a Run key value named Everything, install or tdll, autostart names Kimsuky used to persist its PebbleDash based tools under benign looking labels. The autostart relaunches the implant at logon while masquerading as ordinary software. Detecting these value names surfaces registry persistence tied to the campaign.
