Knowing those photos were deleted long ago, I can only imagine the creepy effort that went into this. Feeling for everyone who got hacked.

Actress Jennifer Lawrence has a small collection of her photos leaked.  Ariana Grande whose pictures as well has been posted stated that these were fake. What remains unclear is, how did the hacker obtained all these pictures from the iCloud account? Is it mere password guessing, social engineering or by breaking into the system?

At the time of publishing, administrators of 4Chan have blocked access to these threads as these victims are high profile personality. There will surely be strong investigation which will follow.
