Hello,
I have PLC V280-18-B20 and SCADA GE Cimplicity
I have a SW that monitores network assets and traffic, and it noticed (first time) that there was an attempt to communicate from the PLC to SCADA on port 56780
This is the first time that PLC initiates communication with the SCADA
And this is the first time I can see unitronics using port 56780.
The firewall dropped the session, but it looks suspicious to me,
Did anyone expirienced something like this?
