Smug Nia :3 (aka) @notzecoxao is back with another great scene release on his GITHub Repo!
@zecoxao has released siscon which is a Syscon firmware decrypter for PS4. I've checked the source code and it requires three key related files; sys-key, sys-iv and sys-cmac which are not included. However, some keys (mirror) where leaked in previous story about the PS4 Syscon.
Thanks goes to @GaryOPA for the heads up about @notzecoxao's tweet earlier.
