Frida 12.1 Released ∞
release
oleavr
Massive changes under the hood this time. All of our dependencies have been upgraded to the latest and greatest. Let’s have a look at the highlights.
V8 7.0
Frida’s V8 dependency was previously at 6.2.2, and has now been upgraded to 7.0.242. The move to such a new version means that the V8 debugger API is gone and has been replaced with the new Inspector API, which the latest Node.js is also using. One thing that’s pretty awesome about it is that it’s natively supported by Google Chrome’s Inspector.
To start using it, just tell Frida to use V8, by calling session.enable_jit(), and then session.enable_debugger().
Or when using the CLI tools:
$ frida-trace --enable-jit --debug -f /bin/cat -i readThen in Google Chrome, right-click and choose “Inspect”, and click on the green Node.js icon in the upper left corner of the Inspector. That’s it, you are now debugging your Frida scripts. That means a nifty console with auto-completion, pause/continue, stepping, breakpoints, profiling, and heap snapshots. What makes it really convenient is that the server listens on your host machine, so you can call enable_debugger() on a session representing a process on your USB-tethered Android device, and it all works the same.
Here’s what it looks like:
Note however that V8 is currently not included in our prebuilt iOS binaries, but it should be possible to get it running again on iOS now that it’s able to run without RWX pages. We do however plan on bridging Duktape’s binary debugger protocol behind the scenes so debugging “just works” with Duktape also, though probably with a slightly reduced feature-set.
Process.id
It is often quite useful to know the PID of the process that your agent is
executing inside, especially in preloaded mode. So instead of requiring you
to use NativeFunction to call e.g. getpid(), this is now a lot simpler as
you can use the brand new Process.id property.
Anything else?
No other features, but some really nice bug-fixes. Thanks to mrmacete we are now able to attach to com.apple.WebKit.* processes on iOS 11.x. And thanks to viniciusmarangoni this release also packs a couple of goodies for frida-java, fixing one Android 8.0 regression and adding the ability to properly instrument system_server.
Enjoy!
