Details of the eHarmony (unconfirmed) Breach

• in categories: breach • by: Kevin Yank (CTO)

Given the magnitude of this breach, we have set up this special page to provide updates.

If you have any questions, you can find all our contact details here.

We have received from an anonymous source a file containing 34.7 million email addresses along with a claim that the eHarmony customer database has been compromised.

Here are the facts:

  • The file contained the list of email addresses in a hashed (unreadable fingerprint) format.
  • The filename provided was ‘full_eh_sha1.txt’.
  • The message accompanying the file indicated that it was an eHarmony breach.
  • Update: The message also claimed that the original file included detailed customer information, including passwords.
  • It was claimed the breach occurred prior to Feb 1, 2011.

You can check if your address is included in the breach using our anonymous, free check on our front page.

As we can’t be certain that this leak is in fact eHarmony’s customer database, the breach has been published with its source displaying as ‘eHarmony (unconfirmed)’ in our repository.

We have attempted to contact eHarmony’s privacy team for further analysis.
