A pirate copy of Aquaman circulating among torrent sites could suggest that iTunes DRM has been broken (via TorrentFreak).
The movie copy is the high-quality 4K version. The title “Aquaman.2018.2160p.WEB-DL.DDP5.1.HDR.HEVC-MOMA” is telling, because WEB-DL means it came from streaming and download services like iTunes and Netflix.
It appeared on online shortly after the iTunes release, so the timing lines up. There are also no 4K versions of the movie on Netflix or Amazon, so it couldn’t have come from those sources. Vudu has a 4K version but the pirated version appeared before it went on sale.
The movie could just be mislabeled, but if it’s correct it would be the first known 4K WEB-DL pirated movie. One anonymous source said,
Apple has 4k only on Apple TV running tvOS. I assume they skipped checks, if the device is jailbroken, and someone just dumped the encrypted stream and decrypted it via what’s in memory as keys.
