During dynamic analysis of a mobile application, we often want to know what the return value of a certain function is, or we might even want to change how the function behaves. We could patch the binary and run it again, or maybe attach a debugger, but there are quite a few steps to accomplish this on Android/iOS. Luckily, there is a much nicer solution using the Frida dynamic instrumentation kit (https://frida.re). Frida allows us to dynamically hook functions, print their arguments and return values, and even modify their implementation. The best thing? While Frida was developed with mobile applications in mind, it can be used on a whole range of other platforms! In this webcast, I will explain how Frida works, what it can do, and demo how powerful it can be.
