A hack on the online adult dating and hookup FriendFinder network exposed more than 400 million users' information, according to a report from breach notification website Leaked Source.
The hack includes data from more than 339 million accounts on AdultFriendFinder.com, which advertises itself as the "world's largest sex & swinger community," and millions of accounts on sex sites Penthouse.com and Cams.com, Leaked Source reported.
According to Leaked Source, the hack occurred via a Local File Inclusion exploit. Leaked Source did not make the data searchable by the public.
In a statement to The Washington Post, FriendFinder Networks said it was investigating the situation, though it did not confirm nor deny the hack.
"Immediately upon learning this information, we took several steps to review the situation and bring in the right external partners to support our investigation," the statement said.
