A massive data breach targeting adult dating and entertainment company Friend Finder Network has exposed more than 412 million accounts.

The hack includes 339 million accounts from AdultFriendFinder(.com), which the company describes as the “world’s largest sex and swinger community.”

That also includes over 15 million “deleted” accounts that wasn’t purged from the databases.

On top of that, 62 million accounts from Cams(.com), and 7 million from Penthouse(.com) were stolen, as well as a few million from other smaller properties owned by the company.

The three largest site’s SQL databases included usernames, email addresses, and the date of the last visit, and passwords, which were either stored in plaintext or scrambled with the SHA-1 hash function, which by modern standards isn’t cryptographically as secure as newer algorithms.

LeakedSource said it was able to crack 99 percent of all the passwords from the databases.

The databases also included site membership data, such as if the user was a VIP member, browser information, the IP address last used to log in, and if the user had paid for items.
