Double Counter data breach

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 data leaked

• Email addresses
• Geographic locations
• Names
• Usernames

What to do if you had an account

1. 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.
2. 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.
