ULP Breach: Login URLs and Passwords for 4M Accounts

HEROIC analysts identified a stealer log simply named ULP, uploaded to a Telegram channel on October 30, 2025. The file contained 4,012,557 records, each pairing an email address with a plaintext password and the exact login URL of the account it unlocks.

Why This Is Dangerous

Look closely at what a single record in this file actually contains: not just an email, but the precise web address where that email and password combination works. That level of detail removes every barrier an attacker would normally face, they know exactly where to type the stolen credentials in.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs for the associated accounts

Why This Matters

At over 4 million records, this leak gives attackers enormous scale for credential stuffing campaigns against banks, email services, and online retailers. Because so many people use the same password on multiple sites, a single exposed record here can lead directly to account takeover, then identity theft, then financial fraud.

How Stealer Logs Work

Stealer malware spreads through cracked software, fake game cheats, or malicious downloads disguised as legitmate files. Once it infects a device, it scans the browser for every saved password and autofill URL, bundles the results into a log, and that log eventually surfaces on Telegram or dark web marketplaces, just like this one did.
