NINHO PRIVATE HOTMAIL Data Leak Exposed 1,991 Passwords

What HEROIC Analysts Found

HEROIC analysts found a stealer log file named "NINHO PRIVATE HOTMAIL" posted to a Telegram channel on June 18, 2026. The file contains 1,991 records, each made up of an email address, a plaintext password, and the URL of the site the login was used on.

Why This Is Dangerous

Every record in this file is a ready-to-use login. Because the passwords are unencrypted, anyone who downloads the file can read them instantly and try logging in with the paired email and URL, no cracking tools or technical skill required.

What Was Exposed

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

Why This Matters

If any of the 1,991 people in this dump reused their password elsewhere, that reused password becomes a key to other accounts too, from email and banking to shopping and social media. Attackers automate this process, testing stolen logins across many sites at once in a technique called credential stuffing.

How Stealer Logs Work

Stealer logs come from malware planted on a victim's computer, often through pirated software, fake updates, or malicious attachments. The malware copies saved browser passwords and active sessions, sends them to the attacker, and the stolen data is packaged into a file like this one for sale or free distribution on Telegram.
