Researchers Find RedLinePremium Log With 57,370 Records

HEROIC analysts found a stealer log labeled REDLINEPREMIUM on a Telegram channel, containing 57,370 records. The data was uploaded in January 2023, and includes email addresses, plaintext passwords, and internal URLs pulled directly from infected devices.

Why This Is Dangerous

Because the passwords in this log are plaintext rather than hashed, anyone who obtains the file can log in immediately, with no cracking or guessing required. The explicit "premium" branding also suggests the seller was actively marketing this specific log to buyers, rather than dumping it for free, which means the data has likely already changed hands more than once.

What Was Exposed

• 57,370 individual records
• Email addresses
• Plaintext passwords
• Internal and endpoint URLs
• Data first observed: January 2023
• Origin: United States

Why This Matters

At over 57,000 records, this is a sizeable batch of live credentials. Plaintext passwords work the instant they are downloaded, and because so many people reuse the same password across accounts, a single credential from this log can be tried against email, banking, or workplace logins through automated credential stuffing, leading to account takeover or financial fraud.

How Stealer Logs Work

A stealer log is generated by infostealer malware that infects a device and quietly copies saved browser passwords, autofill data, and visited URLs before sending it all back to the attacker. The "RedLine" name referenced in this log's branding points to one of the most widely used infostealer tools in circulation, known for harvesting credentials directly from browsers. Because the data comes straight from the browser's storage, it appears in plaintext instead of the hashed form a legitimate company database would use. These logs are then packaged and sold on platforms like Telegram, exactly where HEROIC researchers found this one.

Check If You Are Affected

With more than 57,000 records in this single log, the odds of being affected are real. Run a free check with HEROIC's breach scanner to see if your information is included. It searches a database of more than 400 billion leaked records to show you instantly whether you have been exposed.
