4Passwords Uploaded by a Telegram User: 2 Records Exposed Online

Two Login Credential Pairs Surface From a Telegram Combolist

In July 2026, HEROIC analysts flagged a small combolist file shared on Telegram by a user operating under the handle "4Passwords." The file contained two exposed records, each pairing an email address with a plaintext password, along with an associated URL. Though limited in size, this leak adds to the steady stream of small combolists that circulate on Telegram every week, each one another opportunity for attackers to test stolen credentials against real accounts.

Why This Is Dangerous

The passwords in this leak were stored and shared in plaintext, meaning anyone who obtained the file could read them instantly, no cracking or decryption required. If either of the two people behind these records reused their password on another site, that same password could be used to log into their email, banking, or social accounts without their knowledge.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs

Why This Matters

Small combolists like this one are often merged with dozens of others to build larger credential-stuffing lists. Attackers feed these lists into automated tools that try each email and password pair across banking, email, and shopping sites. A single successful match can open the door to account takeover, financial fraud, or identity theft, even when the original leak involved only a couple of records.

How Combolists Like This One Are Built

A combolist is a simple text file listing stolen credentials in an "email:password" format. They are assembled from many sources, including old breaches, phishing pages, and malware-infected devices, then shared on Telegram channels where they get combined, resold, or given away. Even small combolists with just a few entries get pulled into larger compilations that attackers use to target thousands of accounts at once.

Check If You Are Affected

HEROIC's free breach scanner searches more than 400 billion leaked records, including combolists like this one, to tell you if your email address has been exposed. If you find a match, updating the affected password and any accounts where you reused it is the fastest way to close the door on attackers.
