Good Uploaded by a Telegram User: 310-Record Combolist Leak Surfaces

In November 2025, HEROIC analysts identified a combolist file circulating on Telegram that exposed 310 records containing email addresses, plaintext passwords, and the URLs of the accounts they unlock. Unlike breaches tied to a single hacked company, this file was compiled and uploaded by an individual Telegram user, a common way stolen credentials get repackaged and passed around before they end up for sale.

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 login. Paired with the URL for each account, anyone who obtains this file can attempt to log in immediately, with no cracking or guesswork required. That combination of email, password, and destination URL is exactly what automated login tools are built to exploit.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each account

Why This Matters

Even a small file like this one can cause outsized damage because people reuse passwords across multiple sites. If any of the 310 exposed credentials match a password someone still uses elsewhere, attackers can attempt credential stuffing, account takeover, and, if financial or personal accounts are involved, identity theft or fraud. Scale is not the only measure of risk. A single reused password is enough to compromise an email inbox, a banking app, or a social media account.

How This Combolist Was Built

A combolist is a plain text file that pairs usernames or emails with passwords, often collected from multiple smaller sources such as old breaches, phishing pages, or malware-infected devices, then combined into one list. Telegram has become a popular distribution channel for these files because it is fast, free, and hard to police. Once uploaded, a combolist like this one can be downloaded, copied, and reused by anyone, which is why even small uploads spread quickly.

Check If You Are Affected

If you use any of the same login details across multiple sites, now is a good time to check. HEROIC's free breach scanner searches a database of more than 400 billion leaked records to tell you whether your email or credentials have shown up in this or any other exposure, so you can change passwords before someone else uses them first.
