Intercept Android traffic using QEMU, mitmproxy and Frida
Recently, I wanted to take a look at the network traffic of an Android App that I was using. I did this a while back when, it was relatively easy to configure an HTTP Proxy and import a custom CA cert to mitm a HTTPS connection but was aware that it got more difficulty in the recent years. This guide describes the setup I used to still achieve my goal.

Debuging API clients using http reverse proxies
While developing API clients it can often be helpfull to inspect the traffic that gets sent to the server. For HTTP APIs this can be easily achieved by using mitmproxy in reverse mode.
