Ninho Private Mix Leak: 2,284 Passwords Exposed, Yours Could Be One

HEROIC analysts identified a combolist called Ninho Private Mix, uploaded to a Telegram channel on July 7, 2026. Despite being labeled "private," the file, containing 2,284 records that pair email addresses with plaintext passwords and the URLs where each login works, is now circulating publicly.

Why This Is Dangerous

The "private" label typically means the list was originally sold or shared only within a closed group before leaking further. Combined with plaintext passwords, that means these 2,284 accounts can be accessed immediately by anyone who now has the file, without any need to crack or decode the data first.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Once a supposedly private list spreads beyond its original buyers, more people gain the ability to test these credentials elsewhere through credential stuffing. If you reused a password from an account on this list anywhere else, that single password can unlock multiple accounts, leading to account takeover, financial fraud, or identity theft.

How Combolists Work

A combolist is a compiled file of email or username and password pairs, often built from stealer logs or older breaches and organized with matching URLs so each credential can be used right away. Lists marketed as "private" are usually sold at a premium on the assumption they have not been widely distributed, but as this leak shows, that exclusivity rarely lasts.

Check If You Are Affected

With 2,284 records now public from this leak, checking your exposure takes only a moment. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including combolists like Ninho Private Mix, to tell you instantly if your email has been compromised. If you find a match, change that password everywhere you have reused it right away.
