What happened

In October 2026, the Discord server protection service Double Counter suffered a data breach attributed to a vulnerability in the Metabase analytics tool. In its disclosure notice, Double Counter advised that attackers gained access to a subset of its data. A corpus of data was subsequently published publicly and contained 275k unique email addresses and Discord usernames. A small number of records belonging to paying subscribers whose purchases were processed via Stripe were also present and included names, countries and postcodes.

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.
  • Geographic locations: A general location recorded on your account, such as a country, state, city, postcode or region, either typed in by you or estimated from your IP address.
  • Names: Your first name, surname and sometimes middle name or initials, as you gave them when you signed up. It appears in almost every breach because nearly every account asks for it.
  • Usernames: The handle or login name you chose for an account, which may be public on forums, games and social platforms or used privately to sign in.
