adb reverseĪdb reverse is used to set up a reverse socket connection from the Android device to the computer that the device is connected to. This can be done by using adb reverse and modifying the iptables on the device. Instead we need to route the device’s traffic on the desired ports through PolarProxy. Since PolarProxy is run as a transparent proxy we can’t use the normal proxy settings and set up PolarProxy as a proxy. Running PolarProxy and listening on two ports Android setup You also want to use the -w argument and provide a filename to specify where the decrypted traffic should be saved.Īs an example PolarProxy -p 3883,3883 -p 443,80 -w polarproxy.pcap would start PolarProxy and listen to port 3883 and 443 and save the decrypted traffic in the file polarproxy.pcap. The third is optional and specifies the outgoing port, if not specified the listening port is used. The first specifies which port to listen to, the second which port to use in the decrypted pcap file. This argument takes a comma separated list of numbers. If you want PolarProxy to listen to several ports you can use several -p arguments. Running PolarProxyĭecide which ports you want PolarProxy to listen to and use the -p argument to specify this.
WIRESHARK TLS 1.2 DECRYPT INSTALL
Start PolarProxy with PolarProxy -p 443,80 -certhttp 10011 and load localhost:10011 in a browser to download PolarProxy’s certificate.Īfter you’ve downloaded the certificate you can shut down PolarProxy again and install the certificate on your Android device in the same way as described in Sniffing https traffic on Android 11. Many modern browsers are blocking port 10080, so use something else, like for example 10011. In the documentation on their web page they are using port 10080 for this, but you should avoid it. To do this you need to start PolarProxy with the -certhttp argument.
The first step is to get the actual certificate. To make sure that the Android device doesn’t reject the traffic we need to install PolarProxy’s certificate as a trusted certificate. Since PolarProxy intercepts and decrypts all TLS traffic going through it, it encrypts the traffic with its own certificate.

Feel free to leave a comment if you can get the SOCKS or HTTP CONNECT proxy working together with Android. I haven’t been able to get the SOCKS proxy or HTTP CONNECT proxy approach to work for my use cases so I’m going with the transparent proxy approach. Since version 0.9 PolarProxy can be run as a transparent proxy, a SOCKS proxy or a HTTP CONNECT proxy.

PolarProxy is free to use and available for both Linux and Windows so it should be available to most people. These can later be analyzed using Wireshark. It is a transparent TLS proxy that decrypts TLS traffic and can save the decrypted traffic as pcap files. PolarProxy is a neat tool that can help us. What we need is a TLS proxy that is capable of decrypting TLS encrypted traffic.
Since we’re interested in intercepting TLS traffic on Android this means we can’t use Wireshark to decrypt the traffic. But if you want to intercept traffic from other programs or from Android you will generally be out of luck. If Wireshark has the pre-master secret it will be able to decrypt the traffic.Ĭurl and browsers such as Chrome and Firefox for computers can generate these secrets when the connection is set up.
This is generated by the client when setting up a secure connection with the server. The other way is to provide Wireshark with the pre-master secret. The first is using the private key the server is using to encrypt the traffic, but this is something you generally don’t have access to when analyzing Android applications. There are two ways that Wireshark can decrypt TLS traffic. The traffic is all encrypted, you can't really see much more than the domain Wireshark is a great tool for capturing raw network packets, but if the traffic is encrypted with TLS it makes things complicated.
To do this you will need a rooted Android device (or emulator) that’s connected to a computer using adb.
WIRESHARK TLS 1.2 DECRYPT HOW TO
If TLS is used things get complicated, so in this article I’m going to explain how to intercept generic TLS traffic that goes to and from an Android device. This is often very convenient, but sometimes you need to go deeper and look at the raw network packets. In the article Sniffing https traffic on Android 11 I described how you can intercept https traffic on Android.
