Someone Has Your Password: 13,468 EU Credentials Leaked

HEROIC flagged a credential collection titled "UHQ EU Combo" distributed by hqhotmailcomboowner on Telegram in November 2024. This dump contains 13,468 records targeting European users, with all passwords in plaintext and labeled "Ultra High Quality"—meaning the credentials were likely verified as active at the time of release.

Plaintext and Verified: The Worst Combination

The passwords in this collection are not just in plaintext—they carry the UHQ designation, indicating they have been tested and confirmed to work. This double threat means that the 13,468 affected European users face an immediate and active risk. Their credentials are not just exposed; they are packaged and ready for exploitation by anyone who downloads the freely available file from Telegram.

What Was Exposed

• Email Addresses — European accounts spanning multiple countries and services
• Plaintext Passwords — verified working credentials in fully readable text
• URLs — the specific login pages where each credential grants access

The Urgency of Credential Stuffing With Verified Data

When attackers work with verified credentials, their success rate in credential stuffing campaigns jumps dramatically. Instead of blindly testing millions of potentially expired passwords, they start with 13,468 confirmed working pairs and expand outward. Each verified European email-password combination is tested against banking platforms, government services, cloud providers, and social media. For users who share passwords across accounts, the compromise can escalate from a single leaked credential to total digital identity theft within hours.

From Infected Devices to Curated EU Combo Lists

The data in this dump originated from infostealer malware infections across Europe. The malware—typically delivered through localized phishing campaigns, fake software updates, or compromised websites—captures every credential stored in the victim's browser. The operator hqhotmailcomboowner then filters the raw logs by geographic region, selects European credentials, verifies a subset as still active, and publishes the result as a curated UHQ collection. This specialization by region makes the dump particularly useful for targeted attacks against European financial institutions and services.
