US Data Breach: HOT 1 uploaded by a Telegram User Leaks 1,049 Records

In October 2024, HEROIC analysts identified a combolist titled "HOT 1 uploaded by a Telegram User" circulating on a Telegram channel. The file contained 1,049 records pairing email addresses with plaintext passwords, along with URLs linking each credential set to the site or service it was taken from. Because the passwords were stored and shared in plaintext, anyone who downloads this file can use the credentials immediately, with no cracking or decryption required.

Why This Telegram Combolist Is Dangerous

Combolists like this one are built specifically for reuse at scale. Since the passwords are already in plaintext, an attacker does not need any special tools or technical skill to try them against other websites. With 1,049 email and password pairs tied primarily to accounts in the United States, this file gives criminals a ready-made list to test against email providers, social media, banking, and shopping sites, hoping that people reused the same password in more than one place.

What Was Exposed in the HOT 1 Combolist

• Email addresses
• Plaintext passwords
• URLs linking each credential pair to its source site

Why This Matters for Anyone in the File

Because these passwords were never hashed or encrypted, they are usable the moment someone opens the file. That makes this exact type of leak a common launchpad for credential stuffing, where attackers automate login attempts across many sites using the same email and password combination. If you reused this password anywhere else, that account is exposed too. From there, account takeover, unauthorized purchases, and identity theft become real possibilities, especially if the accounts touched hold personal or financial information.

How Combolists Like This One Are Built

A combolist is simply a text file of "combo" entries, typically email:password or username:password pairs, gathered from earlier breaches, leaks, or stealer logs and compiled into a single list. They are often assembled and shared for free or sold cheaply on Telegram channels and dark web forums, exactly as happened with this file. Because a combolist can pull from many different original sources, the credentials inside can be old, recent, or a mix of both, which is why checking whether your own information appears in one is worth doing even if you don't recognize the source.

Check If You Are Affected

You don't have to guess whether your email address turned up in this combolist or any other leak. HEROIC's free breach scanner checks your email against a database of more than 400 billion exposed records, including combolists, stealer logs, and database dumps like this one. Run a free scan now to see if your information was exposed, and change any reused passwords right away if it was.
