Routine browsing of NetFlow yielded the following:
Connections to: 129.78.131.94 Port: 61070/TCP
PTR: dp-dellxp08.physiol.usyd.edu.au.
Connections detected from two MacOS hosts and one Vista host to this IP.
Data:
- Investigation on Vista host indicates process responsible for the connection is Skype. Skype is running but NOT logged in on this host.
- A look at all three Skype instances show only two common contacts, one of which is unlikely to be at this IP address.
- The remaining is the "Skype Test Call" - username:echo123.
- Placing a call generates mainly UDP traffic - and not to this IP.
- Logging out of Skype created activity as per attached snip. FIN packets tell us the game was over for now.
Conclusion: Possibly some sort of Skype ping. Non-conclusive.
