4,291 Accounts at Risk After NINHO PRIVATE MIX Data Leak

What HEROIC Analysts Found

HEROIC analysts uncovered a stealer log file called "NINHO PRIVATE MIX" uploaded to a Telegram channel on June 16, 2026. The file holds 4,291 records, each pairing an email address with a plaintext password and the website URL where that login was used.

Why This Is Dangerous

The direct consequence of this leak is that 4,291 sets of working login credentials are now circulating outside their owners' control. Because the passwords were stored in plaintext, no cracking or guessing is required. An attacker can simply copy the email, password, and URL and attempt to log in right away.

What Was Exposed

• Email addresses
• Plaintext passwords
• Website URLs tied to each login

Why This Matters

The real risk shows up when people reuse the same password on more than one site. If any of the 4,291 affected accounts share credentials with an email provider, bank, or shopping account, those accounts become targets for credential stuffing and account takeover, often within hours of a log like this being shared.

How Stealer Logs Work

Stealer logs are produced by malware that quietly infects a device, often through a cracked program, a fake installer, or a malicious file attachment. Once running, it harvests saved browser passwords, autofill data, and active login sessions, then transmits everything to the attacker. The result is packaged into a log file and posted to marketplaces or Telegram channels, exactly where NINHO PRIVATE MIX was found.
