Gameing Combo Uploaded by a Telegram User: 1,642,927 Passwords Leaked

In May 2026, HEROIC's threat intelligence analysts identified a combolist file circulating on Telegram, uploaded by an anonymous user and containing 1,642,927 records. The file, tracked as "Gameing Combo uploaded by a Telegram User," bundled email addresses together with plaintext passwords and the URLs of the sites those credentials belong to, effectively handing out ready-to-use logins to anyone who downloaded it.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext, there is no encryption or hashing standing between an attacker and a working password. Pairing each password with its matching email address and the URL of the login page removes the guesswork too. An attacker does not need to crack anything or guess which service a credential works on. They can simply plug the combo directly into a login form and see if it works.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each credential pair

Why This Matters

Combolists like this one are a favorite tool for credential stuffing attacks, where automated bots feed millions of email and password pairs into login forms across many websites at once. If you reused a password from this list on any other account, whether it's email, banking, or social media, that account is now at risk of takeover. From there, attackers can lock you out, drain financial accounts, or use your identity to commit fraud.

How Combolist Leaks Work

A combolist is a compiled text file of "combo" entries, typically formatted as email:password, sometimes with a URL attached to show which site the credentials belong to. These lists are usually assembled from older breaches, stealer logs, or credential harvesting campaigns, then repackaged and shared on platforms like Telegram, where they circulate freely among cybercriminals. Because the data is often aggregated from multiple sources, a single combolist can affect people who have never heard of the original breach it came from.

Check If You Are Affected

The safest move is to find out whether your email address appears in this leak or any of the others sitting in HEROIC's database of more than 400 billion breached records. HEROIC's free breach scanner checks your email against that database in seconds, so you can see what's exposed and change any reused passwords before someone else gets to them first.
