unusual traffic outbound and TVUPlayer
I've just started the forensics on this, but wanted to see if anyone had a similiar experience with this software... A user downloaded/installed/used a TV viewer (http://tvunetworks.com/) -- the our IDS guy received a report from SourceFire that there was an unusually large OUTbound data stream... Basically, during the timeframe the user noted a process still running that was associated with this application, anywhere from 113 - 163 megs had been downloaded (the TV data stream -- expected) but at the same time about 1.5 gigs of data was outbound (NOT expected!). All done over the course of a few hours.
The destination of the data streams was to seven different IPs. IT troops claim the system is free of known viruses and bad-ware. We don't know yet what data was actually outbound; only have the SourceFire report to run on so far. Yes, lots to do yet (ports, dest lookups, etc.).
Here's a summary:

Ideas? Any Experience with TVU?
