Exploits Club Summary:
Have you ever sat down and thought âgosh, I wish someone would just document how Binder works from front-to-backâ? Well, it appears thats what the Android Red Team had the same idea. Following their Binder research presented earlier this year at OffensiveCON, the team has now released just under 9k words going through all things Binder internals. The post is broken into 5 major sections: Lifetimes of Objects, Concurrency Model, Workqueues and Work Items, Binderâs Buffer Allocator, and the Transaction stack. It comes complete with supporting code snippets for each subsystem and diagrams to help visualize some of the more complex dataflows. Overall, its a golden resource for anyone in the Android space who is interested in getting spun up on Binder quickly.
