I'm analyzing Android games with Fiddler 2 to see how the game collects data. There is a problem, both Fiddler 2 and Charles Proxy doesn't capture any traffic from some online games. All i got are ads traffics.

I have ensure that I have enabled proxy on Android system, have certificate installed, filtered target process and check if https decryption is working. All fine. I have reseted cert and fiddler 2 but it doesn't help

I have heard it uses socket system, i don't know excatly what he meant. This online game requests a lot of data. I checked logcat and i see that the game retrieved some json data but there is not enough infomation.

I'm missing something there?

  • Use iptables. Check out blog.dornea.nu/2015/02/19/redirect-androids-traffic-to-burp

  • Proxies are easy to circumvent/not support. If you need better network analysis i suggest you set up a proper man in the middle.

  • Tried iptables but the game failed to connect. Viewing https websites still working fine. I don't know what to do since i'm quite new to MITM. I just want to see game request/response

  • In case your target makes use of ‚websockets‘, then OWASP ZAP can help intercept its traffic. Here‘s a guide owasp.org/index.php/Testing_WebSockets_(OTG-CLIENT-010) May 2 '19 at 3:31

    You can try to launch game using frida and load one of ssl unpin scripts (1, 2, 3, 4, etc.). Jan 27 '20 at 9:54

Fiddler and Charles Proxy are web debugging proxies so they only capture http/s traffic. If the game doesn't use the http protocol the trafic wont appear in these tools.

I believe Burp by PortSwinger will do the work.

I found another software called HTTP Debugger. It does way better job capture everything that others couldn't. It is a paid software, but it's really worth for me
