    Snapchat

    Hi All,

    Anybody know where the snapchat app connects to? the webpage is blocked here but the app still works. Finding students taking pictures and sending all day.

    Cheers

    If you have an Android handy, you can find out:

    - Install Network Log (root only) or Connection Tracker (should work with any device)
    - Enable logging in chosen app
    - Send a message in Snapchat
    - Open Network Log/Connection Tracker and see where Snapchat connected



    It's likely they use multiple servers though, so you might want to try it a few times to see if you can find a range/selection of IPs to block

    Some webfilters such as the iBoss have this built in, but try blocking 'feelinsonice.appspot.com' and this should block Snapchat.

    Did you try using one of the apps I suggested to find out what it's connecting to?

    my NGF is reporting my phone as connecting to 173.194.66.141 with an app id of snapchat. I think a lot of the problem seems to be that it is connecting via 1e100 servers and no packets rock up with snapchat along the side!

    Just an update for those who search on this thread. You will find this url is also useful for allowing/preventing snapchat :-

    feelinsonice-hrd.appspot.com

    I've been able to block the Android app for Snapchat, but not on iOS. Looking at the network traffic associated with the iOS version of the app it appears to be routing data through the APN servers and/or Verisign.

    All to intentionally fight around web filters. I've reported my findings to Apple because I believe this would be a violation of the APN terms of use, but we'll see if anything happens. I'm doubtful.

    I was able accomplish that using the "block snapchat" feature in our iBoss web filter. I think the snapchat application blocker feature in our Watchguard XTM firewall also blocks it. As for the exact URL or method that is being used by the iBoss or Watchguard I'm not sure. Neither one blocks snapchat on iOS though because the iOS app is routing through Apple and/or Verisign servers based on what I'm seeing in my logs.

    Even though blocking the URLs noted above (feelinsonice...) is supposed to work it doesn't as there is some sort of logic where Snapchat is using any SSL path on appspot.com to get by content filters. How to solve it? Block appspot.com entirely. Might break other things but it is easier to whitelist individual URLs than deal with Google's desire to bypass filters worldwide. Not allowing simple blocking of Apps for businesses or educational environments is unacceptable Google. Very close to blocking all Google sites if this keeps up.
