Thanks guys for the tute. Got stuck on my first attempt then reinstalled frida server and tools. Worked perfectly next time around and I now have my own 2 files. Cheers

[ezshre]

Hello, I get through all the steps but when I try to run the last one, it says the file or directory does not exist, even though I clearly see it does exist when using ls in that directory


Anyone know why?

[bogpudding]

I'm getting the same error as the guy above me. Followed the steps, I have frida-server-16.1.4-android-x86 in Sdk/platform-tools.

However, when I attempt the last step for frida-server, I get the error "No such file or directory."

I've triple checked for mistakes but can't spot any. Any answers appreciated.

Ending up figuring out the problem, use Pie as the android system image when creating the virtual machine

Sorry, would you mind clarifying what you mean by using Pie?

EDIT: Never mind I see what you mean, will report back if it works.

It did end up working, thanks!

I did run into some other problems that I also ended up fixing as well (had to install pycryptodome which my PC didn't have for some reason). Did get it running eventually though.

Can you create a guide for TLS? :O

[Mrachan]

I followed this guide, but I needed to figure out some things to make it work.

1. I needed to create an emulator with Pixel 6 and Android 9. dump_keys doesn't work with Android 13 right now.
2. I needed to update the value of KNOWN_DYNAMIC_FUNC in Helpers/scripts.js. You need to pull /vendor/lib64/libwvhidl.so from the emulator and run "nm -D libwvhidl.so | grep ' T ' | awk '{print $3}' | grep -v '_'" to get the list of functions you need to add to that array.
3. I installed Firefox on that emulator, download version 103 from apk mirror and install it via adb. (The available image didn't have a Play store, Chrome wasn't installed).

You don't have an Android Device or don't want to buy one to get the two magic files to decrypt your video with drm?[/B][/SIZE]






Your beautilful and free Phone is ready !


Let's play with the terminal....
Open a Command Prompt in Windows.

pip install frida

pip install frida-tools

Now Go to https://github.com/frida/frida/releases

Download The Frida Server for Androïd. and put it on C:\Users\yourname\AppData\Local\Android\Sdk\platfo rm-tools

Verify that the frida-server version you download is the same that the one you have install via pip.


you can show my frida-server file on the screenshot below...

put yourself in the right directory and type

adb.exe devices

We can see that our virtual device is recongnized.

How to Open a Command Prompt in Windows and install Pip? I tried the "Terminal" tab of Android studio to enter the code but it reponds:
pip : The term 'pip' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the
path is correct and try again.
At line:1 char:1
+ pip install frida

+ CategoryInfo : ObjectNotFound: (pip:String) [], CommandNotFoundException

Cool Cedric,

Very straight forward explanations!

Just a question, following your guide, i had got one bin file and one json file as shown in the attached screenshot.
Is this normal? can i use the json file as "device_private_key"?
I'm do the work on a apple M1 machine.

FuLong

It didn't work then. Check point 2 of my previous message. When it works, you will get the private key.

[fulong]

Thanks Mrachan,

I have got the keys by following the guide on a x86 machine!
Maybe the reason is due to the mismatch of the arch between android device and the frida-server.

cheers.

Absolutely terrific guide, completed in 15 minutes, cannot thank you enough

[bonfire62]

FYI if you're having this issue due to a previous install,

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates

downgrade your protobuf to 3.2

pip3 install protobuf==3.20

Just wondering, using this guide, we can dump level 3 CDMs?
And different site may using different levels of DRMs?

Yes, Some sites use L1 and others L3. This guide is for those that want to target sites that use L3

[Onepunch]

Just a tip for those having issues with the demo page. I was able to get the keys to generate using Crackle. No other site seemed to want to play nice with the default chrome installed on android pie.

@adrian_mando1995, Bro, thanks for the clarification!

I need help for this

@HemaElqady
I believe you need to issue these command one line at a time (wait 5 seconds between execution just to be safe).
Also frida-server-16.1.8-android-x86_64 is wrong, you need the one that reads frida-server-16.1.8-android-x86(no "_64" at the end), HERE is direct GitHub download link for it, open your browsers download panel to see it downloading.

Dont forget to extract the file, before pushing it to the Android device, good luck.

If you have a phone, then why are you trying to run the x86 version? You probably need ARM.

What phone do you have?

From the hostname of the phone I could gather it's a Samsung Galaxy S III Neo, which isn't an x64 capable SoC.
You need the frida-server-xx.x.x-android-arm.xz version. Keep in mind, I assume a device this old might not run the Android version needed to run frida, which forces you to run an older version of frida. This is totally fine, just try to keep the version of frida between phone and pc as close as possible to prevent errors.

Then you need https://github.com/frida/frida/releases/download/16.1.8/frida-server-16.1.8-android-arm.xz

The instruction at first page is:

Open Google Chrome and go to

https://bitmovin.com/demos/drm or another site using drm.
Can I use another Browser as FireFox?
