U.S. Users Targeted: NINHO Mix Leak Exposes 1,886 Logins

What HEROIC Analysts Found

On 29-Jun-2026, HEROIC's dark web monitoring team identified a stealer log posted to Telegram under the name "NINHO PRIVATE MIX uploaded by a Telegram User." The log is tagged to United States-based accounts and contained 1,886 records, each one pairing an email address with a plaintext password and the URL of the site that login was used on.

Why This NINHO Mix Leak Is Dangerous

Because this log specifically targets United States-based accounts, it gives attackers a focused pool of victims who are more likely to share common services like the same banks, retailers, or streaming platforms. Every record already lists the exact site each stolen password belongs to, meaning the guesswork of figuring out where a login works has already been done for the attacker.

What Was Exposed in This Leak

• Email addresses belonging to United States-based accounts
• Plaintext passwords captured directly from infected devices
• URLs identifying exactly which websites each login unlocks

Why This Matters for U.S. Users

With 1,886 records concentrated on United States accounts, this leak is a strong candidate for regional credential stuffing campaigns that target popular American banks, retailers, and email providers. If you're in the United States and reuse passwords across services, an exposed login here could open the door to your other accounts as well.

How Stealer Logs Work

Infostealer malware infects a device, often through pirated downloads or malicious attachments, and quietly copies saved passwords and autofill data from the browser without the user noticing. Attackers sometimes sort or label logs by country or region, as with this United States-focused file, to make it easier to target victims who are likely to use the same regional services.

Check If You Are Affected

If you're based in the United States, this kind of regionally focused leak is worth taking seriously. HEROIC's free breach scanner searches more than 400 billion leaked records, including stealer logs like this one, so you can check your email in seconds and secure any exposed accounts before they're targeted.
