The RedLine Cl0ud4 Leak Exposed 8.36 Million U.S. Accounts

"FRESH ULPP Redline_Cl0ud4" Stealer Log Exposes 8,360,466 Records

HEROIC analysts identified a massive stealer log file labeled "FRESH ULPP 20-07-2026 Redline_Cl0ud4" that surfaced on a Telegram channel on July 20, 2026. The file contained 8,360,466 records, including email addresses, plaintext passwords, and the URLs of the accounts those credentials unlock. The "Redline" reference in the file name points to RedLine Stealer, a well known piece of malware used to harvest exactly this kind of browser data, while "ULPP" refers to the URL, login, and password format the stolen data is organized in.

Why This Is Dangerous

With more than 8.3 million records in a single file, this is one of the larger stealer log dumps to circulate recently. Because the data was harvested directly from infected devices, the passwords are stored in plaintext rather than hashed. Paired with the matching URL for each account, an attacker has millions of ready-to-use logins already sorted by the site they belong to.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the accounts the credentials belong to

Why This Matters

At this scale, it is virtually certain that a large number of these 8,360,466 people reused a password across other accounts. Attackers exploit that habit through credential stuffing, running automated tools that test leaked email and password pairs against banking, email, and social media logins. That process can lead directly to account takeover, identity theft, and financial fraud for a huge number of victims from one single leak.

How Stealer Logs Work

RedLine Stealer, referenced in this file's name, is malware that spreads through cracked software, fake downloads, and malicious attachments. Once it infects a device, it quietly collects usernames, passwords, autofill data, and browsing history straight from the browser and sends it back to whoever controls the malware. Individual infections are combined into large "fresh" batches like this one and uploaded to Telegram channels for others to use.

Check If You Are Affected

Given the scale of this leak, checking your email is strongly recommended. HEROIC's free breach scanner checks your address against a database of more than 400 billion leaked records, including massive stealer logs like this RedLine dump.
