CSA 4.0.3 Skype making IRC connections.

Does Skype make IRC connections?

We are detecting this all the time from multiple ports:

"Potential worm propagation: The process 'C:\Program Files\Skype\Phone\Skype.exe' (as user ) has read downloaded content (file C:\Program Files\Skype\Phone\Skype.exe) and attempted to access an email or network related resource (making a Network IRC connection, 6//6737).This is considered suspect. The user chose 'Terminate (as default)'."

Skype Tech support said that Skype UDP traffic is mistakenly considered by CSA as an IRC connection.

This is a known "bug" in Cisco Security Agent.

I have searched for that bug but could not find any thing related.

Any thoughts?

Re: CSA 4.0.3 Skype making IRC connections.

Hi .. I would be very cautious about using Skype .. in one of our customers CSA reported Skype's processes capturing keystrokes .. so who really knows what goes on in the background ..


Re: CSA 4.0.3 Skype making IRC connections.

4.0.3 does have it's limitations. I would question their tech support a bit further. We get messages from web pages initiating IRC connections and it's usually because there is some sort of messaging window open on the page.

You could create a rule that monitors Skype and logs what connections it makes and what and where it accesses if you want more info.

You might also try a test install of 5.x and see if it sheds more light on the situation.
