NINHO PRIVATE HOTMAIL Leak: Search Your Email for 652 Exposed Logins

NINHO PRIVATE HOTMAIL Combolist: What HEROIC Analysts Found

On 07-Jun-2026, HEROIC threat analysts identified a combolist file titled "NINHO PRIVATE HOTMAIL" circulating after being uploaded by a Telegram user. The file contained 652 records pairing email addresses and usernames with plaintext passwords, along with associated URLs tied to the accounts. Unlike a single-company data breach, a combolist like this is typically assembled from multiple sources and shared for immediate use in automated attacks.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who obtains this list can log in directly to the affected accounts without cracking or guessing anything. Attackers can use the included URLs to identify which services the credentials belong to, then attempt to log in immediately. If any of the 652 people in this leak reused these same email and password combinations elsewhere, those other accounts are at risk too.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Combolists like this one are the raw fuel for credential stuffing attacks, where automated tools test stolen email-and-password pairs against banking sites, email providers, and social media platforms. When a password shows up in plaintext, the risk multiplies: it can be reused instantly, and it may reveal the person's typical password pattern for other accounts. This is how a single small leak can escalate into full account takeover, identity theft, or financial fraud.

How Combolists Work

A combolist is a plain text file that pairs login identifiers, usually emails or usernames, with passwords, one pair per line. Criminals build these lists by combining credentials pulled from older breaches, phishing campaigns, or malware logs, then repackage and redistribute them on forums and messaging apps like Telegram. Because combolists require no technical skill to use, they circulate widely and get tested against dozens of popular websites within hours of being posted.

Check If You Are Affected

If you have ever used a Hotmail or similar email address with a password you still use today, it is worth checking whether your information appears in this leak or others like it. 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 whether your email has been exposed and take action before someone else does.
