Sniff complete wlan/wwan traffic of thirdparty application

[siebeneicher]

Hello folks,

i would like you to ask a question about the network facilities of iOS. I have a project which includes to track the whole network traffic of a third-party application installed on my iphone. So therefore I am not able to modify the application and what i am interested in, is to know what that application send as data and receives as data over the network, WLAN or WWAN. In fact the whole possible ways, that application interacts with the a remote machine or server or device.

So from what i know, it might be possible to trace the network traffic via tcpdump in jailbraik mode. That might deliver us a pcap file which i can analyse on my laptop via wireshark. So one question i do have is, how i can address a package to an iphone application, or other words, how can i know which packages comes from my application? I guess tcpdump don't give the information, so i ask if iOS allow me with root access to get this information internally anywhere?

And might this work also WWAN? Because its probably not using tcp, right?

Please, if anyone have some information, it might be greatly welcome.

Thanks in advance,

Markus

What I would do to make things easier

- Open an ad-hoc network on your computer and connect your device to it.
- Share your primary internet access with the Wifi Client
- Disable all automatic push/fetch/notifications on the device
- Run Wireshark on the computer to sniff the network
- Now use your app and see on your computer to see network traffic.

No needs to jailbreak and because every other network activities on your device are disabled you should only have network traffic from your app. Worst case, run the sniffing without the app running so you will see what's going on on the network that is not related to your app.
