alextu Posted August 27, 2019 Report Share Posted August 27, 2019 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? Quote Link to comment Share on other sites More sharing options...
