I suspect the commenter you’re responding to means ~”who leaked the source code referenced in the DMCA, and why”. The DMCA takedown request refers to a repo that it claims contains internal information and data from the claiming company.

According to this repo Symantec just filed a DMCA notice to Android source code about a week ago:

https://github.com/github/dmca/blob/master/2019/04/2019-04-0...

Crazy.

Why crazy? They do list every .. folder (and call them 'repositories'), which is probably stupid. But

https://github.com/shil99/android_test/tree/master/external/...

literally has their name in the path/package name, so it isn't crazy (unless you know more?) to believe that this was stolen/reverse engineered Symantec code, no? At LEAST it's a very confusing and misleading directory tree for a random repository?

Files below src/ should be sources, not a 3rd party Symantec lib or whatever, so I'd give them the benefit of the doubt here.

What android source code? It's a repos called android_test of some user.

This seems to have been the main factor - com/symantec/mobilesecurity - in the code.
