ULP Leak: 6,255 Credentials Exposed by a Telegram Upload

ULP: 6,255 reasons to check your passwords today. That's the blunt reality after a Telegram user uploaded a file labeled simply ULP on May 15, 2025, a file that turned out to contain 6,255 sets of usernames, passwords, and the exact websites they unlock.

Why This Is Dangerous

ULP is short for username, login, password, and it's basically a shorthand name that criminals give to combolists pulled from stealer malware. Unlike a leak from one specific company, a ULP file mixes credentials from dozens or hundreds of different websites into a single, easy to search list. That makes it a favorite tool for account takeover attempts because the passwords are already sorted by site.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs for each login
• 6,255 total records

Why This Matters

Because the passwords weren't hashed or encrypted, there's absolutely no barrier between the file and a working login. Anyone with basic scripting knowledge can automate login attempts across banking sites, email providers, and shopping accounts in minutes. If you've ever reused a password, and honestly most of us have at some point, a single exposed credential can unravel access to seperate accounts you thought were unrelated.

How Stealer Logs Work

Files like this one usually begin as info-stealing malware that infects a device through a pirated app, a malicious ad, or an infected attachment. The malware quietly copies saved browser passwords and autofill fields, then ships everything back to whoever controls it. That data then gets cleaned up, formatted, and posted to Telegram channels under generic names like ULP so it can be resold or traded imediately.

Check If You Are Affected

The only way to know for sure if your email showed up in this ULP file, or in any of the thousands of similar leaks out there, is to actually check. HEROIC's free breach scanner searches more than 400 billion leaked records in seconds, so you can find out where you stand and change any exposed passwords before someone else uses them.
