AdultFriendFinder has been hacked, revealing the account details of more than 400 million people who would undoubtedly prefer to keep their identities private on the "world's largest sex and swinger community" site.
The hacked database—which appears to be one of the largest ever single data breaches in history—apparently contains account details for numerous adult properties belonging to the California-based Friend Finder Network, and includes customers' e-mail addresses, IP addresses last used to log-in to the site, and passwords.
According to data breach notification site LeakedSource.com, the passwords were either kept in plain text format, or used the largely discredited SHA1 hashing algorithm. It claimed to have cracked 99 percent "of all available passwords" which "are now visible in plaintext."
Around 339 million accounts were stolen from AdultFriendFinder.com. More than 15 million accounts which users thought they had deleted but which weren't purged from the database were also hit. Beyond that, 62 million accounts from Cams.com and seven million from Penthouse.com were compromised alongside smaller amounts from other properties. Penthouse.com was sold to Penthouse Global Media in February.
The exposed data revealed some interesting habits among swingers: for example, Hotmail is the most popular e-mail account among users of the site, closely followed by Yahoo mail.
