Skype false positive

L3 Networker

Hello guys,

About skype: how to know, when users realy use skype and when PA detects only false positive? Because now i have lot of log with "secure.skype.com" URL and PA detects it as skype application.. I would be grateful for an explanation.

Hi emr,

many thanks for your answer. I can't find skype-probe. So no skype client is being used. I think that users are redirected to a "secure.skype.com" page from some other page or something like that, though I can't say exactly. Because when I type in a web browser "secure.skype.com", i'm redirected to "login.skype.com" and PA log shows few records "secure.skype.com", "login.skype.com" and "apps.skypeassets.com".  And when I look at users log, I only see "secure.skype.com" records. I'm trying to figure out how this happens.

If the user is using skype client, you can find skype-probe in traffic log as below:

I can see all URLs you mentioned. (URL category name might be different from you because I'm using PAN-DB instead of BrightCloud)

What is 'users log' you are pointing to?

Do you mean detail log for 'secure.skype.com'?

URL log. I use filter: (url contains skype).

Well, it looks like your PaloAlto device places between client PC and proxy server.

I'm not using proxy. This might causes different result.

Maybe. Anyway thank you for help Smiley Wink
