The NINHO PRIVATE HOTMAIL Leak: 780 Emails and Passwords Exposed

In June 2026, HEROIC analysts identified a combolist labeled "NINHO PRIVATE HOTMAIL" circulating after a Telegram user uploaded the file. The list contains 780 records pairing email addresses with plaintext passwords, along with the URLs where those credentials were originally used. Why This Is Dangerous: because the passwords in this file are stored in plaintext, anyone who downloads the list can read them instantly, no cracking or decryption required. Paired with the matching email address and site URL, an attacker has everything needed to log directly into an account without guessing anything. What Was Exposed: email addresses, plaintext passwords, and the URLs tied to each set of credentials. Why This Matters: email accounts are the recovery point for almost every other online service. If someone can log into your inbox, they can reset passwords on your banking, shopping, and social media accounts one by one. This kind of exposure is a common starting point for credential stuffing, where automated tools test the same email and password combination across hundreds of other sites, and for full account takeover. How This Combolist Was Likely Built: combolists like this one are typically assembled by combining credentials from older breaches, phishing pages, or malware infections into a single file, then formatted as email and password pairs for easy reuse. They are frequently shared for free in Telegram groups to build a seller's reputation before larger, paid lists are advertised. A small file size doesn't mean small risk, every line represents one real account. Check If You Are Affected: the only way to know for sure if your email and password showed up in this leak, or any of the thousands of others HEROIC tracks, is to check. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including combolists like this one, so you can find out in seconds if your information is exposed and take action before someone else uses it.
