What it detects

This rule detects msiexec installing an MSI package staged in the C:\PerfLogs directory, observed in a Huntress-tracked intrusion where attackers deployed the Atera RMM agent from PerfLogs for persistence. PerfLogs is a non-standard software staging location and legitimate installers rarely run from it. Installation of remote management software from this path indicates attacker-driven persistence tooling.
