The NINHO PRIVATE HOTMAIL Breach Put 449 Logins Online

On June 3, 2026, HEROIC analysts found a stealer log named "NINHO PRIVATE HOTMAIL" after a Telegram user uploaded it to a channel used for sharing stolen credentials. The file holds 449 records, each combining an email address with a plaintext password and the URL of the site the login was captured from, and all 449 of those pairs are now sitting in a public Telegram channel for anyone to download.

Why This Is Dangerous

The passwords in this file are stored in plaintext, meaning they can be read and used exactly as the account owner typed them. The included URL for each entry removes the need for an attacker to guess where a stolen password might work, pointing them directly to the correct login page.

What Was Exposed

• Email addresses (Hotmail accounts)
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

Account takeover is the immediate risk for the 449 people in this file, since their login and the site it unlocks are listed side by side. Reused passwords widen that risk through credential stuffing, and because Hotmail addresses often serve as the recovery email for other accounts, a single breach here can open doors elsewhere.

How the NINHO PRIVATE HOTMAIL Log Was Built

Logs carrying a "private" label like this one are typically compiled by malware running on infected devices, gathering saved browser passwords and anything typed into login forms, then packaging the results together for the person controlling the infection. Once assembled, the data is shared or sold on Telegram channels dedicated to trading stolen credentials, giving anyone with access to the channel a copy of the file.

Check If You Are Affected

If you use a Hotmail account, it is worth checking your exposure now. HEROIC's free breach scanner searches more than 400 billion leaked records, including stealer logs like this one, to show you whether your email or password has surfaced anywhere on the dark web. Run a free scan and change any password that comes back compromised.
