microsoft 7 Combolist Leak: How 1,213 Credential Pairs Got Exposed

What HEROIC Analysts Found in the "microsoft 7" Combolist

HEROIC's dark web monitoring team identified a file called "microsoft 7" uploaded to Telegram and dated May 6, 2026. It is a combolist containing 1,213 records that pair email addresses with plaintext passwords and the URLs of the accounts they unlock.

Why This Leak Is Dangerous

Because the passwords in this file are plaintext and each one is matched to a specific URL, an attacker can attempt to log into every listed account immediately. There is no decryption step and no guessing, just a ready-made list of email, password, and destination.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each account

Why This Matters

Credentials like these are used in credential stuffing attacks, where attackers try the same email and password against many other sites, hoping a person reused it. That can lead to account takeover, identity theft, or financial fraud, especially if the accounts reached include email or banking logins.

How a Combolist Like This One Gets Made

A combolist is built by collecting email and password pairs from earlier breaches, malware infections, or phishing campaigns and combining them into a single file for easy distribution. Files are often named after a theme or target, as this one is, then uploaded to Telegram channels where they are shared or sold to other criminals looking for ready-to-use logins.

Check If You Are Affected

It only takes a moment to find out if you were exposed. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, so you know quickly if action is needed. If your information is found, change the affected password and any others like it right away.
