Someone Has Your Password: 26,791 Redline Cl0ud4 Credentials Leaked

In July 2026, HEROIC identified a stealer log collection labeled Redline Cl0ud4 28K Hits being shared on Telegram. This dump contains 26,791 compromised records — credentials that have been verified as active by the threat actor, making them especially dangerous. All passwords are stored in plaintext, meaning they are ready for immediate use.

Verified Plaintext Passwords: Maximum Danger

Not only are these passwords stored in plaintext, but the "hits" designation indicates they have been tested and confirmed to work. This means attackers have already verified that these email-password combinations successfully log in to real accounts. Victims face not just theoretical risk but active, confirmed compromise of their credentials.

What Was Exposed

• Email Addresses — tied to active, verified accounts across the internet
• Plaintext Passwords — confirmed working and ready for unauthorized access
• URLs — showing exactly which services and accounts are known to be compromised

Credential Stuffing With Verified Data

When attackers have verified credentials, credential stuffing becomes even more effective. They know these passwords work on at least one service, so they systematically try them on every other platform the victim might use — banking, email, cloud services, social networks. The success rate with verified credentials is dramatically higher than with raw dumps, making this dataset particularly valuable to cybercriminals.

How RedLine Malware Harvests Credentials at Scale

RedLine is one of the most widely deployed infostealer malware variants. It infiltrates systems through phishing attachments, fake software installers, and compromised advertisements. Once running, it extracts every saved password from the victim's browsers, steals session tokens, copies autofill data, and even captures cryptocurrency wallet information. The data is compiled into structured logs and uploaded to command-and-control infrastructure before being distributed on Telegram.

Check If Your Credentials Were Exposed

If your credentials appear in a verified hits list, they are actively being traded and exploited. Act now. HEROIC's breach scanner monitors over 400 billion compromised records from data breaches and stealer logs worldwide. Search your email address or domain to find out if you are affected, and change your passwords on every service immediately if a match is found.
