Revision as of 15:05, 3 August 2009

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.

Potential Skype Traffic?

Conclusion: Possibly some sort of Skype ping. Non-conclusive.
