Breach verification service LeakedSource claims it has obtained over 400 million user accounts stolen by hackers from social networking and multimedia entertainment company FriendFinder Networks, Inc.
According to LeakedSource, 412,214,295 accounts have been compromised, including usernames, email addresses and passwords. The data appears to originate from six websites operated by FriendFinder Networks and its subsidiaries.
There are nearly 340 million accounts from Adult Friend Finder, over 62 million from Cams.com, roughly 2.5 million from Stripshow.com and iCams.com, and more than 7.1 million from Penthouse.com, which FriendFinder Networks sold earlier this year to Penthouse Global Media, Inc. Approximately 35,000 accounts come from an unidentified domain.
Unfortunately, many of the passwords were stored in clear text, while the rest were converted to lowercase and stored as SHA1 hashes, which are easy to crack. LeakedSource says it has managed to crack 99 percent of the hashes.
The leaked data can be highly useful to malicious actors, especially the 5,650 .gov accounts and the 78,301 .mil accounts. The compromised information also includes data associated with more than 15 million accounts that had been deleted by AdultFriendFinder.com users.
LeakedSource has decided not to make the compromised data searchable on its website for the general public. If confirmed, this is the largest incident analyzed by the breach notification service.
The company said the user data was stolen by attackers via a local file inclusion vulnerability disclosed by a hacker roughly one month ago. CSO reported at the time that the hacker exploited the flaw to show that it exposed information on Adult Friend Finder databases.
SecurityWeek has reached out to FriendFinder Networks for comment and will update this article if the company responds.
This would not be the first time the details of Adult Friend Finder users are exposed. In May 2015, the website launched an investigation into a breach that reportedly affected over 3.5 million customers.
Last year, hackers also breached the systems of Avid Life Media, the owner of online adultery service Ashley Madison. The details of more than 30 million Ashley Madison users were leaked on the Internet.
