Inside the smsd.org Combolist: How 738 Logins Got Leaked

HEROIC analysts found a combolist named smsd.org uploaded to a Telegram channel on May 25, 2026, containing 738 records of email addresses, plaintext passwords, and the URLs those logins were tied to. The file was verified and added to HEROIC's breach database on August 28, 2026.

Why This Is Dangerous

Because every password in this file is stored as plain, readable text rather than being hashed or encrypted, no cracking or guesswork is required to use it. An attacker simply reads the email, password, and matching URL together and can attempt to log in immediately, exactly as if they had typed it in themselves.

What Was Exposed

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

Why This Matters

Combolists like this one are the raw material behind credential stuffing attacks, where criminals feed thousands of stolen logins into banking sites, email providers, and shopping accounts to find out which ones still work. If a password from this file was reused anywhere else, that reuse is what turns one leaked login into a full account takeover, and from there into identity theft or financial fraud.

How Combolists Work

A combolist takes usernames or emails and passwords pulled from smaller breaches, phishing pages, or infected devices and compiles them into a single text file. There is no advanced hacking involved in building or using one. Files like smsd.org spread quickly across Telegram channels and dark web forums, where anyone can load them into automated software and test every credential pair within minutes.

Check If You Are Affected

Instead of wondering whether your email is one of the 738 caught up in the smsd.org combolist, you can find out directly. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, showing you exactly what was exposed so you know which passwords to change.
