Your Login May Already Be Exposed. The web.de Leak Hit 17,950 Accounts.

HEROIC analysts identified a combolist labeled "web.de" that was uploaded to a Telegram channel on 17 December 2024. The file contains 17,950 records made up of email addresses, plaintext passwords, and the login URLs those credentials belong to.

Why This Is Dangerous

Named after the web.de email service, this combolist targets accounts on that platform specifically. Each of the 17,950 records pairs a working email address with a plaintext password and the exact site it logs into, so there is nothing to crack, just a login to attempt.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs for the associated accounts

Why This Matters

Anyone whose email and password appear in this file is at risk of account takeover, particularly if that password has been reused on other sites. Attackers commonly run combolists like this one through automated tools that test each credential pair against email providers, banking sites, and social platforms, a tactic known as credential stuffing. Because email accounts are often used to reset passwords elsewhere, a compromised email login can open the door to other accounts too.

How Combolists Work

A combolist pairs usernames or email addresses with passwords, one credential set per line, and is usually assembled by combining data from older leaks and stealer logs rather than a single company's breach. Combolists are often labeled by the email provider or site they target, as with this web.de file, before being uploaded to Telegram channels for other users to test at scale.
