DaisyCloud ULP Leak Hits 82,983 Accounts, Like a Small City

Picture a small city, one with roughly 83,000 residents. That is close to how many people were caught up in the "UP_DAISYCLOUD - FOXBASEWORLD ULP-358" file, a leak that HEROIC confirmed contains exactly 82,983 records after it surfaced on Telegram on 08-Jul-2025.

Why This Is Dangerous

ULP stands for URL, login, and password, and that format is precisely wich makes this leak so easy for criminals to weaponize. There is no cleanup work needed on their end, no matching usernames to sites, everything is already lined up and ready to run through automated login tools.

What Was Exposed

• URLs for each account
• Email Addresses
• Plaintext Passwords
• 82,983 total records

Why This Matters

At this scale, a single leak can rival the population of an entire town, and every one of those records represents a real person who now has to worry about their accounts. If nothing is done untill someone notices suspicious activity, the window for an attacker to act goes on far longer than it should.

How Stealer Logs Work

The "ULP" naming convention seen in this file is a telltale sign of infostealer malware output, since that malware is built specifically to grab the URL, login, and password fields together as it works through a victim's saved browser data. Once collected across enough infected machines, an operator like whoever ran "DaisyCloud" and "FoxBaseWorld" bundles it all together and the leak occured from there, ready for distribution.

Check If You Are Affected

Whether you live in a city of 80,000 or a town of 8, your exposure risk is personal, not based on population size. HEROIC's free breach scanner checks your email against a database of over 400 billion breached records, giving you a fast, clear answer.
