This Europe Combolist Means 2.7 Million Accounts Could Be Accessed

HEROIC analysts identified a dataset, tracked as COMBOLIST 2.7M EUROPE MIX FRESH 100, that a Telegram user uploaded on 17-Dec-2025. HEROIC's count shows 2,688,858 records, including email addresses, plaintext passwords, and the login page URLs tied to those accounts, compiled to target a mix of European accounts.

Why This Is Dangerous

Right now, somewhere among these 2,688,858 records, an attacker could be typing in an email address and a plaintext password and simply logging in. There is nothing to crack or guess, the working combination is already sitting in the file, waiting to be used against whichever account it belongs to.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

With 2,688,858 records spread across European accounts, this combolist is large enough to fuel automated credential stuffing campaigns for weeks. If a password from this file is reused, it can lead directly to account takeover, and in more serious cases identity theft or financial fraud.

How Combolists Work

A combolist is built by combining email and password pairs from multiple sources, often older breaches, stealer log malware, and previously leaked databases, then merging and cleaning them into one large file. Sellers label combolists by region, size, and freshness, as seen here with a batch marked for Europe and tagged "fresh," before sharing them through channels like Telegram where buyers test the pairs against real accounts.
