The NINHO PRIVATE MIX Dump: 4,599 Stolen Logins Hit the Dark Web

HEROIC analysts identified a combolist labeled "NINHO PRIVATE MIX" that was uploaded to a Telegram channel on 30 June 2026. The file contains 4,599 records made up of email addresses, plaintext passwords, and the login URLs those credentials belong to.

Why This Is Dangerous

Labeled both "private" and "mix," this combolist blends credentials from multiple sources and was meant to circulate among a smaller group before wider release. Each record pairs a working email address with a plaintext password and the exact site it logs into, so an attacker can act on it immediately with no cracking involved.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs for the associated accounts

Why This Matters

Anyone whose email and password appear among these 4,599 records is at risk of account takeover, particularly if that password has been reused elsewhere. Attackers commonly run combolists like this one through automated tools that test each credential pair against email providers, banking sites, and social platforms, a tactic known as credential stuffing.

How Combolists Work

A combolist pairs usernames or email addresses with passwords, one credential set per line, typically assembled by combining data from multiple older leaks and stealer logs rather than a single company's breach. "Private" combolists are often shared in smaller, invite-only Telegram groups first before circulating more widely, but they work exactly the same way once someone starts testing the credentials.

Check If You Are Affected

To find out whether your email address or passwords appear in this combolist or any other leak, HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records in just a few seconds.
