Karl Trygve Kalleberg - Frida: Putting the open back into closed software
Channel: OSDC Nordic
Date: 2015-05-28

Have this black box process that you're just dying to peek inside of? Is this process perhaps running on your cell phone, or on a closed-source OS, and you just got to interoperate with it? Is the company behind this proprietary software being less than forthcoming with APIs and docs? Well, if you know a little JavaScript and have a little persistence, perhaps we can help.

In this talk, we show what you can do with Frida, a scriptable dynamic binary instrumentation toolkit for Windows, Mac, Linux, iOS, Android, and QNX. We show by example how to write snippets of custom debugging code in JavaScript, and then dynamically insert these scripts into running processes. Hook any function, spy on crypto APIs or trace private application code. No source code, no permission needed!
