Skymail.mn Combolist Exposes 1,497 Plaintext Passwords and Emails

The Skymail.mn Combolist: 1,497 Emails and Passwords in Plaintext

HEROIC analysts uncovered a combolist named skymail.mn that surfaced on a Telegram channel on May 25, 2026, containing 1,497 records made up of email addresses, plaintext passwords, and the URLs of the sites those logins were used on. The file was added to HEROIC's breach database on August 28, 2026, confirming the records as verified and ready to search.

Why This Is Dangerous

Every password in this combolist is stored in plain, readable text rather than being scrambled or hashed. That means an attacker does not need any special tools or technical skill to use the data. They can simply read an email, its matching password, and the site URL, then try logging in directly. There is no extra step standing between this file and a working account takeover.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each login to the site it was used on

Why This Matters

Ready to use credential pairs like these are exactly what fuel credential stuffing attacks, where criminals feed thousands of stolen logins into banking sites, email providers, and shopping accounts to see which ones still work. If you reused this password anywhere else, that single reused password can open the door to account takeover, identity theft, and financial fraud far beyond the original account it was tied to.

How Combolists Work

A combolist is a plain text file pairing usernames or emails with passwords, usually pulled together from older breaches, phishing kits, or infected devices and merged into one master list. These files circulate freely on Telegram channels and dark web marketplaces because anyone, regardless of technical ability, can load one into an automated login tool and start testing thousands of accounts within minutes.

Check If You Are Affected

Rather than wondering whether your email address is one of the 1,497 caught up in the skymail.mn combolist, you can check directly. HEROIC's free breach scanner searches a database of more than 400 billion leaked records to show you exactly what has been exposed, so you know which passwords need to change today.
