A Small juno.com Combolist Still Means 53 Accounts at Risk

In June 2025, HEROIC analysts found a small combolist referencing juno.com, an established email and internet service provider, uploaded by a Telegram user. The file contains 53 records of email addresses and plaintext passwords. Why This Is Dangerous: With only 53 accounts listed, this is a small file, but each entry is a complete, ready-to-use login. Anyone who obtains the file can immediately attempt to log into the affected juno.com accounts and any other site where the same password may have been reused. What Was Exposed: - Email addresses - Plaintext passwords - URLs tied to each login Why This Matters: Small leaks are easy to overlook, but a compromised email account can still be used to reset passwords on other services, read private messages, or impersonate the account owner. Scale does not determine risk for the people whose data is actually in the file. How This Combolist Works: Combolists referencing a specific provider like juno.com are often built by pulling matching accounts out of larger, mixed breach collections and repackaging them by domain, making it easier for a buyer who wants to target users of a particular email service. Check If You Are Affected: Check your juno.com or other email address against HEROIC's free breach scanner, which searches more than 400 billion exposed records.
