907 US Passwords Exposed in the NINHO PRIVATE HOTMAIL Telegram Leak

907 Records Exposed in the NINHO PRIVATE HOTMAIL Telegram Combolist On June 8, 2026, a Telegram user uploaded a combolist file labeled "NINHO PRIVATE HOTMAIL." HEROIC's threat intelligence team identified and verified the listing on July 31, 2026, confirming it contains 907 records made up of email addresses, plaintext passwords, and associated URLs. Why This Is Dangerous Because the passwords in this file are stored in plaintext, anyone who downloads it can use the credentials immediately, with no cracking or decryption required. Paired with the login URLs included in the file, an attacker can see exactly which site each credential belongs to and attempt to sign in directly, or test the same email and password combination against other popular services. What Was Exposed Email addresses Plaintext passwords Associated login URLs Why This Matters Most people reuse the same password across several accounts. When a list like this circulates on Telegram, attackers run the credentials against banking sites, email providers, and shopping accounts in a process known as credential stuffing. A single reused password can turn one small leak into a full identity theft or financial fraud incident. How Combolists Work A combolist is a plain text file pairing usernames or email addresses with passwords, usually assembled from older breaches, phishing campaigns, or malware infections and repackaged for free distribution or resale. Because they require no technical skill to use, combolists are one of the most common tools behind mass account takeover attempts, and they trade hands quickly in Telegram channels like the one this file surfaced on.
