Ultramar.cl Data Leak: 1,041 Passwords Exposed, Act Now

Act Now: The Ultramar.cl Combolist Exposed 1,041 Passwords

HEROIC analysts found a combolist named ultramar.cl uploaded to a Telegram channel on May 25, 2026, containing 1,041 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. This is not a hypothetical risk. These are working credentials, sitting in a file anyone can download right now.

Why This Is Dangerous

There is nothing standing between this data and an attacker's next login attempt. The passwords are stored in plain, readable text, not scrambled or hashed. Whoever has this file can read an email, its exact password, and the URL it belongs to, then try logging in immediately. No cracking, no waiting, no technical skill required.

What Was Exposed

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

Why This Matters

Every hour this combolist stays in circulation is another chance for it to be run through a credential stuffing attack, where criminals test stolen logins against banking sites, email providers, and shopping accounts in bulk. If a password from this file was reused anywhere else, the consequences move fast: account takeover first, then identity theft or financial fraud once the attacker is inside.

How Combolists Work

A combolist compiles usernames or emails with passwords pulled from smaller breaches, phishing pages, or infected devices into one file. Files like ultramar.cl move quickly through Telegram channels and dark web forums, where automated tools can test every credential pair against dozens of sites within minutes of the file changing hands.

Check If You Are Affected

Do not wait to find out the hard way. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including the 1,041 exposed in the ultramar.cl combolist, so you can see exactly what is at risk and change any passwords that need it today.
