Your Passwords May Be Exposed: Redline Cl0ud4 Leak Hit 39K Users

HEROIC analysts tracked a second Redline Cl0ud4 stealer log to the dark web in late June 2026, this one larger than the first. Labeled "41k MIX VALIDD," the file holds 39,488 records of stolen login data, each entry pairing a website address with an email and its plaintext password, all lifted directly from malware-infected devices.

Why the 41k Redline Cl0ud4 Dump Is Dangerous

This is not a leaked database from a hacked company, it is a direct feed of credentials captured the moment victims typed them in. With 39,488 comfirmed working logins, an attacker doesnt need to crack a single password, they just need to try them. Because the file is marked "valid," criminals treat it as a ready-to-use list for breaking into accounts today.

What Was Exposed

• 39,488 stolen login records
• Email addresses linked to each account
• Plaintext, unencrypted passwords
• The specific URLs each credential was used on

Why This Matters

Most people reuse passwords across several accounts, wich means one stolen credential often opens far more than the single site it came from. Attackers run these lists through automated credential-stuffing tools that hammer banking portals, email providers, and shopping sites until a match hits. From there it is a short step to account takeover, drained accounts, and identity theft.

How This Stealer Log Was Built

Info-stealing malware infects a device through a phishing link, a cracked download, or a fake update, then quietly copies every password saved in the browser along with autofill data and session cookies. It bundles everything into a text file and ships it to the attacker, who then distributes it through private Telegram channels like the one where this dump was found. The "Redline" tag in the filename points to one of the most common stealer families in circulation.

Check If You Are Affected

With almost 40,000 accounts in this single dump, the odds that your credentials are included are real. HEROIC's free breach scanner checks your email against a database of over 400 billion exposed records, including this leak, so you can find out immediately and reset anything that needs it.
