What happened
In approximately 2011, an alleged breach of the dating website Zoosk began circulating. Comprised of almost 53 million records, the data contained email addresses and plain text passwords. However, during extensive verification in May 2016 no evidence could be found that the data was indeed sourced from the dating service. This breach has consequently been flagged as fabricated; it's highly unlikely the data was sourced from Zoosk.
What data leaked
- Email addresses
- Passwords
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.
