11,752 Passwords From the Huai Yot Government Breach Surfaced Online

HEROIC analysts found a dataset tied to Huai Yot, the official website of a Sub-district Administrative Organization in Thailand that handles local government public services, circulating on a hacking forum dated August 21, 2018. The breach affected 11,752 users, exposing email addresses paired with plaintext passwords pulled straight from the site's database. Because the passwords were never hashed, this data was ready to use the moment it surfaced.

Why the Huai Yot Breach Is Dangerous

Plaintext passwords matched to their email addresses give an attacker instant access, no cracking, no guessing, just a direct login attempt. For a government portal used to access public services, that also means anyone who reused their password on other accounts faces exposure well beyond this one site.

What the Huai Yot Breach Exposed

• Email addresses
• Plaintext passwords

Why This Matters

Ready-to-use email and password pairs like these are exactly what fuels credential stuffing, where attackers test the same login across banking, email, and other government or personal accounts. Because password reuse is so common, the 11,752 people in this breach face a real risk of account takeover, financial fraud, or identity theft on services that have nothing to do with Huai Yot itself.

How a Database and Combolist Breach Like Huai Yot Happens

This incident is classified as a database and combolist breach, meaning an attacker likely gained direct access to the site's user database, either through a software vulnerability or a compromised administrative account. The extracted email addresses and plaintext passwords were then compiled into a combolist and posted to a hacking forum, where other criminals could use them to run automated login attempts against other websites.

Check If You Are Affected

If you ever used the Huai Yot website, change that password now, along with any other account where you used the same one, and turn on multi-factor authentication wherever it is available. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including this one, so you can quickly find out if your information was exposed.
