The Fappening Investigation: Feds Bust Hacker, Pleads Guilty

One of the people behind The Fappening -- the hacking and release of nude pics and vids belonging to more than a dozen celebrities -- was busted by the feds, and is now pleading guilty.

Ryan Collins was charged with unauthorized access to a protected computer. The feds say Collins is responsible for hacking into the computers of more than 100 victms -- at least 18 of them famous -- and downloading their photos and videos.

According to the docs, he got in through Apple iCloud and Gmail accounts between Nov. 1, 2012 and Sep. 2, 2014 ... using a phishing scheme.

Some of the famous Fappening victims included Kate Upton, Jennifer Lawrence, Kirsten Dunst and Hope Solo. It's unclear if Collins hacked their accounts in particular. He has not been charged with leaking the material to the public.
