NINHO PRIVATE MIX: 133 Plaintext Passwords Leaked on Telegram

HEROIC analysts identified a stealer log file uploaded to Telegram in May 2026, attributed to the NINHO PRIVATE MIX collection. The breach exposed 133 records containing email addresses, plaintext passwords, and URLs. The data was made freely available on a public Telegram channel, putting every affected user at immediate risk of account compromise.

Why Plaintext Passwords Put You at Immediate Risk

This breach is especially dangerous because passwords were stored in plaintext, meaning they require no decryption or cracking to exploit. Anyone who accesses this data can immediately try these email and password combinations on banking sites, social media platforms, email providers, and other online services. The included URLs reveal exactly which websites each victim uses, giving attackers a precise roadmap for account takeover.

What Was Exposed

• Email addresses tied to online accounts
• Plaintext passwords requiring no cracking
• URLs showing which websites and services were accessed

Why Reused Passwords Turn One Breach Into Many

Even a small breach of 133 records can cause significant damage. Attackers use stolen credentials in automated credential stuffing attacks, testing each email and password pair across hundreds of websites within minutes. Because most people reuse passwords, a single exposed login can unlock multiple accounts. This opens the door to account takeover, identity theft, and financial fraud. Once attackers gain access to an email account, they can reset passwords on other services and take control of a victim's entire digital life.

How Stealer Logs Capture Your Credentials

Stealer logs are created by malware that silently infects a victim's device, often through phishing emails, fake software downloads, or malicious browser extensions. Once installed, the malware captures everything the user types, including usernames, passwords, and credit card numbers. It also records which websites the user visits and extracts saved credentials from browsers. The stolen data is then packaged into log files and shared on platforms like Telegram and dark web forums. These logs are particularly dangerous because they contain working, real-time credentials rather than old or hashed data.
