Check Frida is installed and working by listing the currently running apps.

Follow the Frida installation instructions for MacOS and iOS.

It's possible to use a non-jailbroken device if you can include Frida’s libraries in the app - either via debugging an app you own, or repackaging someone else’s app and injecting the dylib.Īs I want to decrypt Safari’s traffic I’m sticking with the Jailbroken phone.

I’m testing with a Jailbroken iPhone 5S running iOS12.4.3, with Frida installed from Cydia.

Extracting TLS Keys and Decrypting iOS Trafficįrida describes itself as a “dynamic instrumentation toolkit”, it injects a JavaScript VM into applications and we can write JS code that runs in that VM and can inspect memory and processes, intercept functions, create our own native functions etc. To decrypt the packets we need the matching TLS keys, Chrome and Firefox will provide these when the SSLKEYLOGFILE environment variable is set but unfortunately there seems to be no equivalent for Safari.įortunately thanks to tools like Frida, we have the ability to implement it ourselves. I’ve filtered the capture to just display the traffic to and from But as the traffic is encrypted using TLS 1.2 we can’t see the contents of the packets. You should see a screen something like this:

If they’re not already installed, install xcode’s command line tools:.

You can find more details in this article from Apple but the basic process is: This mirrors the network traffic from the device to a virtual interface in MacOS and from there the traffic can be captured using tools like tcpdump and Wireshark. Capturing iOS network trafficĪpple support capturing iOS device network traffic via a Remote Virtual Interface (RVI). In this post I walk through how I capture iOS apptraffic using tcpdump, and how I use a Frida script to extract the TLS keys during the capture so that I can decrypt the traffic too. Safari and iOS doesn’t have this feature natively, and proxies like Charles only communicate to the browser via HTTP/1.x so I needed to find another solution. One challenge with analysing HTTP/2 traffic is that it’s encrypted and while Chrome and Firefox support logging TLS keys and tools like Wireshark can then decrypt the traffic.

Sometimes I can use the tools built into browsers, other times proxies, but when I want to take a deeper look and particularly if I’m looking at how a browser is using HTTP/2, I rely on packet captures. If you want to capture the traffic of a specific app, then tap on the ‘Android’ icon in the upper navigation bar and select the app you want to log or monitor.I often want to examine the web traffic generated by browsers, and other apps. By default, Debug Proxy will capture traffic from all apps. On the main screen, tap on the ‘Play’ button appearing in the center-right corner of the screen to start capturing traffic. Install if you want to decrypt SSL traffic. Just like before, you will be prompted to install an SSL certificate. Other than that, Debug Proxy also gives access to other tools that let you do throttle bandwidth, HTTP response and test latency as well as a network security for MITM attack vulnerabilities, web debugging, SSL monitoring, and more. What’s good about Debug Proxy is that its user interface is very intuitive and captures all packets in native code which makes it pretty fast and responsive. Just like Packet Capture, it can capture traffic, monitor all your HTTP and HTTPS traffic, decrypt SSL traffic using MITM technique and view live traffic.

So, if you chose to go with zAnti, I would recommend that you use a dedicated device that is separate from your work or personal device.ĭebug Proxy is another Wireshark alternative for Android that’s a dedicated traffic sniffer. Moreover, for most advanced features to work, it will change a few SELinux configuration settings and put your device into permissive mode.

Apart from that, zAnti can also find security gaps within your existing network and gives you detailed reports on how to fortify the defenses to protect your network from possible attacks.īeing a complete penetration testing tool that was specifically designed for professionals and businesses in mind, zAnti needs root access to work. Some of the things you can do with zAnti include, but is not limited to, modifying HTTP requests and responses, exploiting routers, hijacking HTTP sessions, changing MAC address, and checking target device for vulnerabilities. You can do complete network testing and a whole lot of other tests with a simple tap of a button. ZAnti is not just a simple network sniffer, it is a complete penetration testing tool for your Android device.
