The stolen data includes the sexual orientation of the users, their sexual preferences, and might even potentially reveal who are the ones seeking extramarital affairs. The data also includes email addresses, usernames, dates of birth, postal codes and unique internet addresses of users' computers.
The hack is estimated to have affected 4 million users, including users who have requested the site for a deletion of their accounts.The leaked information contain addresses linked to dozens of government and armed services personnel and members of the British Army.
Channel 4 news, who have been actively tracking such incidents of hacking and information release to the Deep web have found a secretive forum in which a hacker nicknamed ROR[RG] posted the details of users of Adult Friend Finder.
Shaun Harper is among those whose details have been published. Harper, who had requested his account to be deleted stated that, "The site seemed OK, but when I got into it I realized it wasn't really for me, I was looking for something longer term. But by that time I'd already given my information. You couldn't get into the site without handing over information. He added, "I thought the information had gone. These sites are meant to be secure."
Mr. Harper has been targeted with a spate of spam emails ever since his information was leaked. Experts are of the opinion that hackers will further sift through the leaked data to zero down on potential blackmailing targets.
FriendFinder Networks Inc, the owner of Adult FriendFinder have already started working with law enforcement to investigate the matter and have assured customers of strong action in case they are affected.
