There is an issue with the script located here: https://scripts.itarian.com/frontend/web/topic/get-local-administrators-from-all-machines-in-device-list.
After editing the initial variables and running the script I was emailed a list of machines that did not belong to my device list. A brief review of what was sent to me and it appears I was sent over 500 devices from different companies which showed the device name and all Administrator accounts on those devices.
Someone may want to take a look at this and update either the script OR the back end of the application to prevent us from accessing information about environments that are not our own.
