A new report details how a pirated 4K copy of Aquaman could be the first known example of Apple’s 4K iTunes content being hacked. While there could be other explanations, multiple signs are pointing to the film coming from iTunes.

Some have suggested that the file may have been mislabeled, but TorrentFreak notes that the “release has been posted by reputable sources who are certainly not known for making stuff up.”

An anonymous source shared with TorrentFreak one possibility for how the film may have been decrypted from iTunes:

If there is indeed a breach in iTunes we could see more pirated copies of 4K films from Apple land on torrent sites. Notably, the report mentions that may have already begun.

However, if iTunes is in fact the source of the pirated Aquaman 4K copy, Apple may be actively working on patching any flaws that could prevent any further breaches.

These are internal releases from the group DEFLATE and could trace back to iTunes as well.  The bitrate and channel layout for the Spider-Man release certainly seems to suggest so, our source says.
