3.153 Lines Hotmail.com: A Combolist With 2,806 Logins

In March 2026, HEROIC analysts identified a combolist titled "3.153 lines hotmail.com" uploaded to a Telegram channel. The verified file contains 2,806 records, each pairing a Hotmail email address with a plaintext password and a linked URL. Why This Is Dangerous Every password in this file is stored in plaintext, meaning it can be used immediately by anyone who gets hold of the file. Because the list is focused entirely on hotmail.com addresses, it's especially attractive to attackers who specialize in targeting Microsoft accounts, where one working password can unlock email, cloud storage, and any other linked Microsoft service. What Was Exposed in the 3.153 Lines Hotmail.com File Email addresses (hotmail.com) Plaintext passwords URLs linked to each login Why This Matters With over 2,800 credentials in one file, attackers can run automated credential stuffing attempts against banking, shopping, and social media sites. Because the list targets one specific email domain, a successful login often provides access to the victim's primary inbox, which can then be used to reset passwords and gain entry to other accounts tied to that address. How Domain-Specific Combolists Like This Get Built Files sorted by a single email domain, like this hotmail.com-only list, are usually filtered down from larger, mixed-source breach dumps or stealer log collections. Focusing on one domain makes the resulting file easier for a buyer to work through and more predictable in what kind of account access it will provide. Check If You Are Affected If you use a hotmail.com address, it's worth checking whether your login appears in this or a similar leak. HEROIC's free breach scanner searches more than 400 billion leaked records and tells you instantly if your email address has been exposed, so you can change your password before it's used against you.
