What happened
In October 2016, the adult entertainment company Friend Finder Networks suffered a massive data breach. The incident impacted multiple separate online assets owned by the company, the largest of which was the Adult FriendFinder website alleged to be "the world's largest sex & swinger community". Exposed data included usernames, passwords stored as SHA-1 hashes and 170 million unique email addresses. This incident is separate to the 2015 data breach Adult FriendFinder also suffered. The data was provided to HIBP by dehashed.com.
What data leaked
- Email addresses
- Passwords
- Spoken languages
- Usernames
What to do if you had an account
- Change the password. Change your password on this service. If you used the same password anywhere else, change it there too: attackers try leaked email and password pairs on other sites automatically. A password manager makes one unique password per site practical.
- Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
- Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
