Your Data May Be Exposed: The Redline Cloud Leak Hit 3.5M Records

Your login credentials may already be circulating among criminals without your knowledge. In July 2026, HEROIC analysts found a combolist named Redline Cloud ulpss 18 uploaded to a Telegram channel, containing 3,513,809 email address and plaintext password pairs along with the URLs each pair was used on. Why This Combolist Is Dangerous: With more than 3.5 million credential pairs in plaintext, this is one of the larger files HEROIC has tracked recently. Nothing needs to be decrypted or cracked: anyone who downloads the file can immediately test the logins against banking sites, email providers, and social media platforms. What Was Exposed: - Email addresses - Plaintext passwords - Website URLs linked to each login Why This Matters: At this scale, automated tools can test all 3.5 million pairs against thousands of websites within hours. If any of your accounts share a password with an old or unrelated login, this file could be the key an attacker uses to get in, opening the door to identity theft, financial fraud, and account takeover. How a Combolist Like Redline Cloud ulpss 18 Gets Built: Files like this are typically assembled by combining credentials pulled from older breaches, phishing kits, and malware-infected devices into a single searchable list, then renamed and shared or sold in Telegram channels. The name suggests a possible link to Redline, a well known password-stealing malware family, though HEROIC classifies this specific file as a combolist compilation rather than a single stealer log. Check If You Are Affected: Run your email through HEROIC's free breach scanner, which checks against more than 400 billion compromised records, to see if your credentials appear in Redline Cloud ulpss 18 or any other breach.
