In an email to WIRED, a spokesperson for Leaked Source says it received the data from an "underground source who wishes to stay anonymous," but that it checked some of hacked credentials for a set of Adult Friend Finder accounts against previous leaks of data from a hacked password manager to verify that they were real.
ZDNet also obtained a portion of the data and verified its authenticity by contacting affected users.
Any data breach is a bad thing, as it could put your name, email address or other personally identifiable information in someone else's hands.
The newly revealed data breach that affected Adult Friend Finder is arguably even worse.
Passwords were encrypted, but insecurely, and Leaked Source says it has managed to crack 99% of them.
It's not clear who was behind the attack, though Leaked Source says it occurred in October 2016.
But when those credentials link breach victims to sex sites, the consequences go beyond the risk of a hacked credit card or Twitter account and into the realm of humiliation and blackmail.At face value, the hack could be embarrassing for millions of people.Users turn to the website for discreet connections, which is why Adult Friend Finder bills itself as "the world’s largest sex & swinger community." Like the Ashley Madison data breach in 2015, exposure of this magnitude could wreak untold damage on relationships and reputations, not just only for ordinary people, but for public personalities as well.No matter what your demographic or romantic preference is, there's a dating site designed specifically for you. A second hacker named "Peace" claimed similar activity shortly thereafter.Some are geared toward finding lonely people their soul mates. For the Tinder set, serial daters can browse a catalog of faces with the swipe of a thumb. Peace allegedly stole the information from 73 million accounts, which would be leaked to the public. While Adult Friend Finder is vetting the hackers' boasts, Peace and Revolver have been quarreling on Twitter over who deserves credit for the hack.
