NINHO Private Mix Leak: 551 Logins Shared as Private Access

NINHO Private Mix: A Small But Real 551-Record Credential Leak

HEROIC analysts identified a combolist titled "NINHO PRIVATE MIX," uploaded to a Telegram channel and added to our breach intelligence database. The file contains 551 records of email addresses paired with plaintext passwords and login URLs. The credentials were leaked on 21 June 2026.

Why This Is Dangerous

Being labeled "private" suggests this list was circulated among a smaller, more selective group before becoming visible to HEROIC's monitoring, rather than being blasted out widely from the start. Smaller, private lists are often treated as higher quality by attackers, since they tend to be curated rather than scraped indiscriminately, and every record here comes with a plaintext password and the exact URL it unlocks.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

Even a small file of 551 records is enough for a determined attacker to run credential stuffing attempts across banking, shopping, and social media accounts. Because the passwords are stored in plaintext, they require no extra work to use. If you reused a password tied to any of these accounts, you face the same risk of account takeover, identity theft, or financial fraud as someone caught up in a much larger breach.

How a Combolist Like This Gets Built

A "private mix" combolist is typically assembled from a handful of smaller sources and shared within a limited circle before wider distribution, rather than dumped publicly from the start. The name suggests exclusivity, but the underlying risk to anyone in the file is identical to a public leak: working email and password pairs in the hands of people who did not earn access to them.

Check If You Are Affected

Even small leaks like this 551-record file are worth checking, since a single exposed password can be reused across many accounts. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, so you can confirm whether you are affected and update any passwords that need it.
