3,552 Passwords Exposed in 3.5K MIX Telegram Combolist

HEROIC analysts identified a combolist uploaded to Telegram on 20 August 2026, containing 3,552 records of email addresses paired with plaintext passwords and associated URLs. The file, labeled by its uploader simply as a mixed credential dump, appears to be a repackaged collection of login pairs rather than a breach of a single company's systems.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who downloads it can immediately try each email and password pair against other websites with no cracking or decryption required. If you have reused a password across more than one account, a match here could hand an attacker direct access to your email, banking, or social media accounts within minutes.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs (the sites the credentials were originally used on)

Why This Matters

Combolists like this one are the raw material behind credential stuffing attacks, where automated tools test stolen email and password pairs against banks, streaming services, and email providers at scale. Even a small file of 3,552 records can be enough to compromise thousands of individual accounts, leading to account takeover, identity theft, or financial fraud if the credentials still work.

How Combolists Work

A combolist is a plain text file that pairs usernames or emails with passwords, usually compiled from multiple older leaks, phishing campaigns, or malware infections and merged into one list. Criminals trade and upload these files on platforms like Telegram because they are easy to distribute and easy to automate against login pages. The value of a combolist comes not from being new, but from how many of its entries still work.

Check If You Are Affected

With HEROIC's free breach scanner, you can check whether your email address appears in this combolist or in any of the over 400 billion breached records in HEROIC's database. If your credentials show up, change the affected password immediately and enable two-factor authentication wherever it is offered.
