You can see all the system CAs that are bundled with an Android device by going to Settings -> Security -> Trusted Credentials and viewing system CAs. Since the “traditional” way of installing a user certificate doesn’t work anymore in Nougat and above, for me the easiest solution is to install the Burp CA to the system trusted certificates. Install Burp CA as a system-level trusted CA Note: I did all this with Burp Suite Pro on my Windows 10 machine and am using an Android 7.1 (API25) Genymotion VM, but the steps should be applicable to any setup. Slightly more work, but doesn’t require root privileges. Modify the manifest and repackage the app.Also added benefit of not having to set a lockscreen PIN :) My recommendation for the easiest solution, but does require a rooted device. Install the Burp CA as a system-level CA on the device.There’s two ways to bypass this, and I’ll walk through them both. The failure happens “invisibly” and is responsible for all the alerts I saw in Burp Suite. Unless otherwise specified, apps will now only trust system level CAs. It’s no longer possible to just install the Burp CA from the sdcard to start intercepting app traffic. Starting with Nougat, Android changed the default behavior of trusting user installed certificates. Before I go any further, all the information I needed was found in these great write-ups: I followed the steps I always do but saw nothing but “connection reset” errors in Burp:Īfter a few frustrating hours of troubleshooting, I finally figured out the issue lied with the latest versions of Android (API >= 24). This particular app I wanted to test, however, required a minimum API level 24 (Android 7.0 - “Nougat”) and suddenly it wasn’t working. I run Burp Suite locally, install the User Cert as outlined in Portswigger’s documentation, configure a WiFi proxy and I’m off the races. I’ve done quite a bit of Android testing in the past and my setup usually involves a Genymotion VM or my old rooted Nexus Tablet. I burned a whole afternoon troubleshooting the issue, and decided to write up what I found out and two different ways I got it working. This last weekend I started testing a new Android app for fun, and ran into some trouble getting Burp Suite working properly. Install Burp CA as a system-level trusted CA.
