Inside NINHO PRIVATE HOTMAIL: 3,633 Plaintext Passwords Found

What HEROIC Analysts Found

Looking closer at a stealer log file named "NINHO PRIVATE HOTMAIL," uploaded to Telegram on June 26, 2026, HEROIC analysts counted 3,633 individual records. Every single one pairs an email address with a plaintext password and the URL of the site that password unlocks.

Why This Is Dangerous

The plaintext detail matters more than it might seem. It means none of the passwords need to be cracked or decrypted, they are stored in the file exactly as the victim typed them, ready for an attacker to copy and paste directly into a login form.

What Was Exposed

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

Why This Matters

When 3,633 real, working logins are floating around in plaintext, the danger multiplies for anyone who reuses passwords. A single exposed password often unlocks more than one account, giving attackers an easy path into email, financial, or shopping accounts through credential stuffing.

How Stealer Logs Work

Stealer malware infects a device through a pirated download, a cracked game, or a malicious file, then quietly harvests every password saved in the browser along with active login sessions. The stolen data is compiled into a log file, exactly like this one, and shared or sold on Telegram channels.
