Check Your Inbox: The Hotmail Combo Leak Exposed 1,982 Passwords

What HEROIC Analysts Found in the Hotmail Combo List In June 2026, HEROIC analysts identified a combolist circulating on Telegram under the label "Hotmail Combo." The file, uploaded by a Telegram user on June 8, 2026, contained 1,982 records pairing email addresses with plaintext passwords, along with associated URLs indicating where the credentials were originally used. While this is a smaller combolist compared to some of the larger dumps we track, every record represents a real account with a working password sitting in the open. Why the Hotmail Combo Leak Is Dangerous Combolists like this one are dangerous precisely because they are ready to use. There is no cracking or decryption required. The passwords are stored in plaintext, meaning anyone who downloads the file can immediately attempt to log into the associated email accounts or any other service where the same password might have been reused. The included URLs make this even easier, since they tell an attacker exactly which site or service each login was tied to. What Was Exposed in This Combolist Email addresses Plaintext passwords URLs linked to each set of credentials Why This Matters for the People Affected Even a combolist of under 2,000 records can cause real harm to the people in it. Attackers routinely feed lists like this into automated tools that test each email and password pair against dozens of other popular websites, a technique known as credential stuffing. If any of the 1,982 people in this leak reused their Hotmail password on a banking site, shopping account, or social media profile, that account is now at risk of takeover. From there, the path to identity theft or financial fraud is short. How Combolists Like This One Are Built A combolist is simply a compiled text file of "combo" pairs, usually formatted as email:password or username:password. These files are often assembled by combining data from multiple older breaches, stealer log infections, or phishing campaigns into a single list, then shared or sold on Telegram channels and dark web forums. Unlike a raw database dump, a combolist is built specifically to be plugged into automated login-testing tools, which is what makes it a favorite among low-effort attackers looking to break into accounts at scale. Check If You Are Affected If you use a Hotmail, Outlook, or similar email account, it is worth checking whether your information appears in this or any other leak. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including combolists like this one, and tells you immediately if your credentials have been exposed. If you find a match, change the affected password right away and avoid reusing it anywhere else.
