An adult dating site known as FriendFinder was hacked leading to 3.5 million people’s sexual preferences and secrets exposed. Adult FriendFinder asks customers to detail their interests and based on those criteria matches people for sexual encounters. The site has up to 64 million members and claims to have helped a good number of people find partners, swinger groups, threesomes and a variety of other alternative partners. When signing up for an account, customers must enter their gender, which gender they are interested in hooking up with and what kind of situations they desire.

The hack took place in March and was first uncovered by an independent IT security consultant Bev Robb. She reported the finding on her blog Teksecurity. Teksecurity did not name the site that was hacked but this week England’s Channel 4News reported on the hack that Adult FriendFinder was named as the victim.

The exposed details from the site were of personal nature including email addresses, usernames, birthdays and zip codes in addition to sexual preferences. No credit data has yet been uncovered as part of the hack. Andrew Auernheimer, a computer hacker who looked through the files, used Twitter to publicly identify the Adult dating site customers  that included a Washington police academy commander, an FAA employee, a California state tax worker and a naval intelligence officer who supposedly tried to cheat on his wife. Andrew explained that it was easy to shame government employees.

Millions of other employees’ information remains online making it easy to open and extort any detail from the vulnerable dating site. The information exposed can be very devastating to people living in small towns where they are easily identified.

The breach was carried out by a hacker who goes by the moniker ROR[RG]. In an online hacker forum, he said he blackmailed Adult FriendFinder, telling the site he would expose the data online unless the company paid him $100,000. On the forum hackers praised ROR[RG] saying they were planning on using the data to attack the victims.

FriendFinder Networks Inc, parent company of Adult FriendFinder and other adult sites and publications including Penthouse, said in a statement that it had just become aware of the breach and it is working closely with law enforcement and cyber forensics company Mandiant, The security company assured FriendFinder Networks that it will work vigilantly.
