hotmail.es uploaded by a Telegram User: Your Password Is Exposed

What HEROIC Analysts Found

HEROIC's dark web monitoring team identified a combolist titled "hotmail.es uploaded by a Telegram User," dated to 17 June 2026. The file contains 48,775 records pairing email addresses with plaintext passwords and the URLs of the login pages those credentials were used on. It appears to have been shared through a Telegram channel used to trade combolists, with affected users located in the United States.

Why This hotmail.es Combolist Is Dangerous

Every password in this file is stored in plaintext, meaning there is no encryption or hashing standing in the way of anyone who downloads it. An attacker does not need special tools or technical skill to use these credentials: they can simply open the file and start testing email and password pairs against other websites right away.

The included URLs make this worse. Because each credential pair is tied to the site it was originally used on, attackers know precisely where to try a stolen login first, and can quickly branch out to other accounts if the same password was reused elsewhere.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs associated with each set of login credentials

Why This Matters

Even at under 50,000 records, a combolist like this one is exactly the kind of data used to fuel credential stuffing attacks, where stolen email and password pairs are automatically tested across many other websites at once. Anyone who reused this password on a banking, shopping, or social media account is at risk of account takeover.

Once one account falls, the damage tends to spread. A hijacked email inbox can be used to reset passwords on other services, opening the door to identity theft and financial fraud that can take considerable time and effort to reverse.

How Combolists Work

A combolist is a compiled text file of email-and-password pairs, typically gathered from older breaches or malware infections and then repackaged for free distribution or resale on platforms like Telegram. Rather than coming from a single company's breach, a combolist blends together credentials from multiple sources, which is exactly what makes files like this one useful to attackers running large-scale login attempts against many sites at once.

Check If You Are Affected

The only way to know for certain whether your email and password appear in this combolist is to check. HEROIC's free breach scanner searches more than 400 billion leaked records, including combolists like this one, to tell you whether your information has been exposed. If it has, change that password immediately and make sure it is not reused anywhere else.
