Then just replace “1234” with the process ID of the guinea pig. If you’re on Windows you can run “more” in a cmd shell. If you’re on Mac or Linux, fire up “/bin/cat” in a terminal and let’s use that as our guinea pig. The first argument is the script from above, and the second is the process ID. The important line here is the injection of the script: (script, 1234) Inside “ApplicationWindow”, add a “Script” object: Script But let’s start with something really simple - let’s just have the remote process write something to stdout. Remember that you cannot use plugins and that you must build the dependent libraries such as image. Let’s inject some code, shall we? First, let’s import the Frida plugin by adding this line below the other imports: import Frida 1.0įrida lets us inject JavaScript into any process, and these scripts have access to a quite comprehensive API. Start by installing a static version of the Qt library. We’ll now have some boilerplate code generated by Qt Creator: Name it “geoshark” and go ahead with default settings for the remaining steps. Use the “Qt Quick UI” template in the “Applications” category. Create the projectįirst, let’s fire up Qt Creator and create a new project. If you’re on Linux you will have to build the plugin yourself for now - just follow the Frida build instructions and proceed to building frida-qml the standard Qt way (qmake & make). ![]() Just create a “Frida” directory in your Qt installation’s qml plugin directory and pop in the three files you just downloaded. ![]() ![]() And by the way, remember to download Qt 5.3 first. I would recommend downloading the prebuilt binary for Mac or the prebuilt binary for Windows to get up and running quickly. We’ll leverage frida-qml, Frida’s Qml plugin. ![]() The debugger will inject code into processes to be debugged. We will build a simple, interactive debugger with a Qml-based GUI on top of the Frida cross-platform instrumentation toolkit. Let’s tap into the internals of native processes with our own custom-made debugger. Without modifications of CMake scripts, debug build on macOS and Linux platforms would normally generate dynamic libraries of larger size using DWARF format.
