Description
According to Synel's website the SY-780/A terminal is a stand-alone device used for time & attendance monitoring, production floor control, job costing, and access control applications. It has been reported that performing a port or vulnerability scan against this device or specifically hitting ports 1641, 3734 or 3735, will cause the device to stop responding completely. |
