This is not an iCloud hack, breach, or brute. This story has been spun to (my guess) take away from the big even September 9th.
There isn't a single leak or a single hacker, these images originate from a small celebrity nude ring on the darknet. They typically require people to "buy-in" with an original image.
Considering that celebrities almost all use an iPhone, putting iCloud hack in the headline is sure to grab attention and make some people actually believe it.
If it isn't true, it will die off in a day and nobody will care.
