Our Analysts Found the 1.1K RU MOON Combolist Leaking Passwords Online

What HEROIC Analysts Found

HEROIC analysts came across a combolist called 1.1K RU MOON after it was uploaded by a Telegram user on January 11, 2026. The file contains 1,142 records, each combining an email address, a plaintext password, and the URL of the account it was taken from.

Why the 1.1K RU MOON Combolist Is Dangerous

Small combolists like this one are often overlooked, but 1,142 working email and password pairs is still 1,142 ready-made logins for anyone who downloads the file. An attacker can move through the list one row at a time, testing each password against the site it names, and then checking whether the same password unlocks email, banking, or social accounts elsewhere.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each account's login page

Why This Matters

Even a modest combolist feeds the same credential stuffing pipeline as a massive one. If a password in the 1.1K RU MOON file has been reused anywhere, that single exposed pair can unlock several accounts, leading to account takeover, financial fraud, or identity theft for the people involved.

How Combolists Work

A combolist gathers login pairs, typically email or username plus password, from stealer logs, older breaches, or phishing hauls, then packages them into a single file that is easy to search and reuse. That is how a small, specifically labeled file like 1.1K RU MOON can end up trading hands on Telegram.

Check If You Are Affected

You don't need to track down this combolist yourself. HEROIC's free breach scanner checks your email against more than 400 billion exposed records, including small, targeted combolists like this one, so you can find out in seconds if your password needs to change.
