What it detects
This rule detects inbound requests to the /mifs/403.jsp path on Ivanti Endpoint Manager Mobile, the location of an in-memory Java webshell planted during active exploitation. Access to this path indicates post-exploitation command-and-control against EPMM appliances traced to a single bulletproof-hosted IP.
