Edit: Apple has confirmed that it was breached and celebrities were targeted. https://arstechnica.com/tech-policy/2014/09/apple-confirms-c...

Some of the leaks do look like iCloud backups though. Videos don't get uploaded to Apple's "photo stream" so it would have to be an iCloud backup or, less likely, a local backup that was uploaded to Dropbox. Right now it "feels like" a lot of different leaks and leakers jumping on 4chan and demanding bitcoins for their own little dumps.
