During cdm dumping the functions within are hooked, so while decrypting video, the private key can be extracted.
On Android this is easiest because automatic scripts exist and you can rather easily get root access.
Does this work with the latest widevine decryption? 3 I think?
Method should still work for L3 decryption. L1 decryption is hardware based instead of software based and afaik not possible to crack yet.
Ah, I had the numbers backwards. Is L1 heavily in-use?
Yes. Depends on the platform. For example with Netflix L1 is required for full HD, L3 will only give you access to SD content.
