Telegram Combolist ‘baseD’ Exposes 37,808 Login Credentials

HEROIC analysts reviewed a combolist named baseD, uploaded by a Telegram user and dated August 23, 2026, containing 37,808 email and password pairs. Each record pairs an email address with a plaintext password and a URL, consistent with credentials gathered for reuse against other sites. Because the passwords are readable as-is, checking your email against this file now is the fastest way to know if you are affected.

What a Bundled Login and Password Can Unlock

A combolist hands an attacker a working login rather than a puzzle to solve. With tens of thousands of pairs available, automated scripts can attempt each one against popular email, banking and shopping sites within minutes.

The Fields Captured Inside the 'baseD' Combolist

• Email Addresses
• Plaintext Password
• URLs

How One Leaked Password Opens Several Doors

Since the passwords are stored in plain text, no extra effort is needed before an entry can be tried elsewhere. A single reused password tied to an email account can let an attacker reset other passwords and take over additional accounts in sequence.

The Trade in Lists Like This One

Combolists like this are typically assembled from multiple smaller sources, phishing pages, infected devices and older leaks, merged into one file and labeled before being shared on channels such as Telegram.
