Redline Cloud ULP Dump: 4 Million Stolen Login Credentials Exposed

HEROIC analysts identified a massive combolist called Redline Cloud ulpss 8 that was uploaded by a Telegram user in July 2026. The file contains 4,086,118 records pairing email addresses with plaintext passwords, along with the URLs those credentials unlock, making it one of the larger combolists to surface recently. Why this is dangerous: with over 4 million login pairs stored in plaintext, this file gives attackers an enormous, ready-to-use set of working credentials with no cracking required. The name Redline Cloud points to Redline, one of the most widely used password-stealing malware families, suggesting these logins were likely harvested directly from infected computers before being compiled into a bulk combolist for wider distribution. What was exposed: email addresses, plaintext passwords, and the URLs tied to each set of credentials, covering more than 4 million individual accounts. Why this matters: a dataset this size gives criminals the scale needed to run automated credential stuffing campaigns against banks, email providers, and shopping sites, testing millions of stolen logins in a short amount of time. Anyone among the 4,086,118 people in this file who reused a password on another account faces a real and immediate risk of account takeover, financial fraud, or identity theft. How ULP dumps and stealer logs work: ULP stands for URL, login, and password, the standard format that credential-stealing malware like Redline uses to record what it steals from an infected device. When malware like this infects a computer, it silently harvests saved passwords from browsers and apps, then sends them to the attacker, who compiles the results from thousands of infected machines into a single ULP dump like this one before selling or sharing it. Check if you are affected: HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including large ULP dumps like this one. Run a free scan to see if your credentials were among the 4 million exposed and get guidance on securing any account that used the same password.
