What happened

In June 2025, headlines erupted over a "16 billion password" breach. In reality, the dataset was a compilation of publicly accessible stealer logs, mostly repurposed from older leaks, with only a small portion of genuinely new material. HIBP received 2.7B rows containing 109M unique email addresses, which was subsequently added to the service under the name "Data Troll". The websites the stealer logs were captured against are searchable via the HIBP dashboard.

What was exposed

  • Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.
  • Passwords: The secret you use to sign in, stored by the breached service either in plain text, in a scrambled form called a hash, or encrypted. How it was stored decides how quickly it can be recovered.

What to do now

  1. Check whether your own address is in this dataset with the free email breach check.
  2. Change the password on this service and every other site where you used the same password.
  3. Turn on two-factor authentication on your email account first, because it is the reset path for everything else.
  4. Treat calls and messages that quote real details about you as hostile until you verify them another way.
