5,670 Records Exposed: NINHO PRIVATE MIX Combolist Leak

In July 2026, HEROIC analysts identified a combolist file named "NINHO PRIVATE MIX" circulating among Telegram users. The file contained 5,670 records pairing email addresses with plaintext passwords, along with associated URLs indicating which sites or services each login was intended for.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext rather than encrypted or hashed, anyone who downloads the combolist can read the credentials immediately and start testing them against other websites. Pairing each email and password with a URL makes the file especially usable for attackers, since it tells them exactly where to try each login first.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs/login destinations

Why This Matters

Combolists like this one are the raw material behind credential stuffing attacks. Automated tools take each email and password pair and try logging into banking sites, email providers, and social media accounts in bulk. If you have ever reused a password across multiple accounts, a single exposed credential can lead to account takeover, identity theft, or financial fraud on accounts that were never part of this specific leak.

How Combolist Leaks Work

A combolist is simply a compiled text file of username/email and password pairs, often assembled by combining data from several older breaches or stealer logs into one file. Unlike a hack of a single company's database, a combolist can mix credentials from many unrelated sources. That makes it hard to know exactly where each password originated, but easy for criminals to use since the file is already formatted and ready to load into automated login tools.

Check If You Are Affected

With 5,670 records now circulating from this leak alone, and billions more indexed across other breaches, the safest move is to check your own exposure directly. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including combolists like this one, so you can find out in seconds whether your email or passwords have shown up anywhere they shouldn't be.
