Misconfiguration Manager: Still Overlooked, Still Overprivileged
Duane Michael, Garrett Foster

At Troopers 24, we presented Misconfiguration Manager: Overlooked and Overprivileged, exploring the rampant SCCM misconfigurations that have grown into widely-adopted tradecraft among adversaries and red teams. A year later, the landscape has only grown more interesting - new attack paths have emerged, defenses have evolved (or failed to), and SCCM remains a prime target for privilege escalation, post-exploitation, and domain compromise. In this talk, we’ll explore what’s changed, what’s still broken, and the latest horror stories and tradecraft research shaping SCCM security today.
