L3 Dumper

Script to dump L3 CDM from any rooted Android device.

Things to remember

Does not work on Android 11+. On other Android versions you need to check your device Widevine CDM (to check use application DRM Info). Make sure OEM Crypto API version is 13 or less. Make sure Security Level is L3. If it's L1, you need to install a Magisk module called liboemcrypto-disabler.

Usage

• Download and install Python 3.9.0.
• Install required Python 3.9.0 dependencies using command: pip3 install -r requirements.txt
• Download and install Frida Server application from Google Play store and start the server.
• Enable USB debugging on your Android device and connect it to your computer.
• Execute the script using command: python3 dump_keys.py

After successful run you will have a new folder key_dumps with needed keys inside.

Only getting key_boxes?

Private key dump is possible, you need to modify script.js to include the KNOWN_DYNAMIC_FUNC for your Android device.
