2,547 Login Credentials Surface in the NINHO PRIVATE MIX Leak

2,547 Login Credentials Surface in the NINHO PRIVATE MIX Leak

On June 26, 2026, HEROIC analysts identified a stealer log named "NINHO PRIVATE MIX" after a Telegram user uploaded it to a channel used for trading stolen credentials. The file contains exactly 2,547 records, each pairing an email address with a plaintext password and the URL of the site the login was captured from. It is the latest in a series of similarly named leaks HEROIC has tracked from this source over the past month.

Why This Is Dangerous

The passwords in this leak are stored in plaintext, meaning anyone who downloads the file can read and use them exactly as typed. Paired with the URL for each entry, an attacker can move directly from opening the file to attempting a login, skipping the trial and error that would otherwise slow down an attack.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

With 2,547 records in this file, the risk extends beyond the specific sites listed in the log. Reused passwords can be tested against other services through credential stuffing, and since email accounts often serve as the recovery method for banking, shopping, and social media logins, a single compromised account can open the door to several others.

How the NINHO PRIVATE MIX Leaks Keep Appearing

Files carrying the "NINHO PRIVATE MIX" name are produced by malware running on infected devices, harvesting saved browser passwords and anything typed into login forms, then bundling the results into a file tagged with each site's URL. The same operator appears to release new batches periodically as more devices become infected, which is why HEROIC has tracked several leaks under this name with different record counts.

Check If You Are Affected

Do not assume you are safe just because this is one leak among several. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including stealer logs like this one, so you know right away if your credentials were exposed. Run a free scan and update any password that comes back as compromised.
