HEROIC Uncovers 9.9M-Record RedLine Stealer Log Leak Online

HEROIC Analysts Uncover a 9.9 Million Record RedLine Stealer Log

In July 2026, HEROIC analysts discovered "FRESH ULPP 21-07-2026 Redline_Cl0ud4" on Telegram, one of the larger stealer logs tracked recently, containing 9,885,104 records. Each entry pairs an email address with a plaintext password and the login URL it was used on, output consistent with the well known RedLine infostealer malware referenced directly in the file's name.

Why This Is Dangerous

Nearly 9.9 million plaintext password pairs is an enormous amount of ready-to-use access, all stored with no encryption standing in the way. A file this size can fuel large scale automated attacks against thousands of websites simultaneously, since every credential pair is immediately usable the moment it is downloaded.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs (the exact pages the credentials unlock)

Why This Matters

A leak of nearly 10 million records all but guarantees that a significant number of these accounts share reused passwords with banking, email, or shopping sites. That makes credential stuffing, account takeover, financial fraud, and identity theft realistic outcomes for a meaningful portion of the people whose data appears in this file.

How RedLine Stealer Malware Builds Logs Like This

RedLine is one of the most widely used infostealer malware families in circulation, typically spread through phishing emails, fake software cracks, and malicious ads. Once it infects a device, it silently exports every saved browser password, cookie, and autofill entry, then reports the haul back to the operator. Large collections like "Cl0ud4" aggregate many individual RedLine infections into one massive file labeled "FRESH" to signal recently harvested, still-active credentials.

Check If You Are Affected

With nearly 10 million records in a single leak, the odds that your information is included are real. HEROIC's free breach scanner checks your email against more than 400 billion breached and leaked records, so you can confirm your exposure to this RedLine log or any other and reset your passwords before they are used against you.
