Redline_Cl0ud4 Stealer Leak Exposed Over 6 Million Passwords.

In July 2026, HEROIC analysts identified a massive stealer log breach labeled FRESH ULPP Redline_Cl0ud4, uploaded to a Telegram channel by an anonymous user on 08 July. Verification confirmed the file contains 6,054,969 records, including email addresses, plaintext passwords, and the URLs of the sites each login belongs to, making it one of the larger stealer log dumps HEROIC analysts have tracked recently.

Why the Redline_Cl0ud4 Leak Is Dangerous

Every one of the more than six million passwords in this file was stored and shared in plaintext, meaning anyone who downloads it can use the credentials immediately with no cracking or decoding required. Each record also lists the exact website URL a login belongs to, giving attackers a ready-made map of exactly which account each stolen password unlocks, from email inboxes to banking portals and beyond.

What Data Was Exposed in the Redline_Cl0ud4 Breach

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

At more than six million records, this leak provides more than enough raw material to power large-scale credential stuffing campaigns, where automated tools test each email and password pair across banking sites, email providers, and social platforms. Because so many people reuse passwords across services, a single exposed login from the Redline_Cl0ud4 file can quickly turn into account takeover, financial fraud, or identity theft.

How Stealer Log Breaches Work

The "Redline" name referenced in this file's label points to RedLine, one of the most widely used password-stealing malware families in circulation. This type of malware infects a victim's device and silently harvests saved passwords, autofill data, and login details straight out of the browser, then packages everything, including the site URL tied to each credential, into a single log file. These files are then shared or sold in bulk, often through Telegram channels like the one behind the Redline_Cl0ud4 leak.
