What it detects

This rule detects abuse of a setuid /usr/bin/env binary to spawn a privileged shell with the -p flag on an Ivanti Endpoint Manager Mobile appliance. It maps to post-exploitation activity following EPMM compromise where operators escalate to root using a SUID binary. Detecting this reveals hands-on-keyboard privilege escalation on an internet-facing appliance.
