46,104 Passwords From the RedlineCloudFree Dump Just Surfaced

RedlineCloudFree Stealer Log Breach Overview

In June 2025, a stealer log collection branded as RedlineCloudFree was uploaded to a public Telegram channel, exposing 46,104 records of stolen credentials. The dataset, harvested using the notorious Redline infostealer malware, contained email addresses, plaintext passwords, and the specific URLs where those credentials were used. This dump was marketed as free public logs, making the data accessible to virtually anyone in underground comunities.

Why This Is Dangerous

The RedlineCloudFree dataset is especially alarming because it was distributed freely on Telegram, lowering the barrier for exploitation to near zero. Unlike premium stealer log collections that are sold to a limited number of buyers, free distributions mean thousands of threat actors may already have copies. Redline is one of the most prolific infostealer families in active circulation, known for its efficiency at extracting browser-stored credentials, cookies, and autofill data from compromised machines. Every record in this dataset represents a device that was actively infected with malware, and the plaintext passwords require no additional processing to weaponize.

What Was Exposed

• Email Addresses - Personal and corporate email accounts extracted from infected browsers and credential stores
• Plaintext Passwords - Unencrypted passwords ready for immedite use in account takeover attacks
• URLs - Targeted website addresses showing exactly which services each credential unlocks

Why This Matters

With 46,104 compromised records circulating freely, the scale of potential damage is significant. Each record is not just a username and password pair but a verified credential that was actively in use on a real person's device at the time of infection. The Redline stealer specifically targets saved browser passwords, meaning these credentials were likely functional when harvested. Attackers can use this data for credential stuffing campaigns, identity theft, financial fraud, and as entry points into corporate networks. The free distribution model also means this data has been downloaded, reshared, and incorporated into larger credential databases by now, multiplying the exposure exponentially.

How Stealer Log Distribution Works

The Redline infostealer operates as a malware-as-a-service platform where cybercriminals purchase access to the malware builder and command-and-control infrastructure. Once deployed through phishing campaigns or malicious software downloads, Redline silently exfiltrates saved passwords, browser cookies, cryptocurrency wallet data, and system information from infected devices. The collected logs are then sorted and packaged for sale or free distribution. In this case, the operator chose to release 902 log files publicly through a Telegram channel under the RedlineCloudFree brand, likely as a marketing tactic to attract buyers to thier premium offerings. This practice of giving away samples to build reputation is common in underground marketplaces.

Check If You Are Affected

If your device may have been compromised by Redline or similar infostealer malware, it is critical to check whether your credentials appear in this dataset. HEROIC's data breach scanner covers more than 400 billion compromised records and can identify if your email addresses or passwords were part of the RedlineCloudFree dump or any other known breach. Run a scan now to determine your exposure and take immediate steps to change compromised passwords and enable two-factor authentication on all affected accounts.
