The austromail.at Leak Put 1,012 Austrian Email Accounts Online

HEROIC analysts found a combolist tied to the austromail.at domain, dated June 10, 2026, shared in a Telegram channel. The file contains 1,012 records of email addresses, plaintext passwords, and the URLs those credentials unlock. Why This Leak Is Dangerous: The passwords in this file are stored in plain text, so an attacker can use them immediately without needing to crack anything. Because every address shares the austromail.at domain, this gives criminals a ready-made, focused target list tied to one email provider. What Was Exposed: - Email addresses - Plaintext passwords - URLs connecting each account to the austromail.at service Why This Matters: An email account is often the key to resetting passwords elsewhere, so a compromised austromail.at login can open the door to banking, shopping, or social accounts linked to that same address. Anyone in this list who reused their password on another site is at greater risk of account takeover. How a Domain-Targeted Combolist Like This Works: Criminals sometimes filter stolen credentials by email domain to build a focused list for a single provider, in this case austromail.at, then share or sell it through Telegram channels to buyers who specifically want to target that provider's users. Check If You Are Affected: Run your email through HEROIC's free breach scanner, which checks against more than 400 billion leaked records, to see if your austromail.at account was part of this leak, and update your password immediately if it was.
