One Telegram File Called ‘Ninho Private Mix’ Held 2,750 Passwords

One Telegram post. One file, labeled "NINHO PRIVATE MIX." Inside it, HEROIC analysts found 2,750 records containing email addresses, plaintext passwords, and the URLs tied to each account, uploaded in June 2026 by an individual Telegram user. A single upload like this is all it takes to put thousands of accounts at risk.

Why This Is Dangerous

Every password in this one file is stored in plaintext, so an attacker does not need to crack or guess anything before logging in. With 2,750 email, password, and URL combinations packed into a single download, this file gives anyone who obtains it a ready-made batch of working logins to test against other sites right away.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each account

Why This Matters

It only takes one file like this to affect thousands of people at once. If any of the 2,750 exposed email and password pairs are reused elsewhere, attackers can use them for credential stuffing and account takeover, and from there move into banking, shopping, or social media accounts, leading to identity theft and financial fraud.

How This Combolist Was Built

A "private mix" combolist like this one is assembled by pulling email and password pairs from a variety of smaller sources, such as phishing pages, malware infections, and older leaks, then packaging them into a single file, often labeled "private" to suggest it has not been widely shared before. Telegram makes it simple to upload and circulate a file like this to a select audience before it spreads further.

Check If You Are Affected

One file, thousands of accounts, and there is a simple way to check if yours is one of them. HEROIC's free breach scanner searches a database of more than 400 billion leaked records to show whether your email and credentials appear in this leak or any other, so you can change your passwords before someone else uses them.
