The Redline_Cloud4 Breach Gave Attackers 418,487 Login Credentials

HEROIC analysts discovered the Redline_Cloud4 fresh stealer log circulating on the dark web, uploaded by a Telegram user on May 21, 2026. The dataset contains 418,487 records and exposes email addresses, plaintext passwords, and URLs collected from devices infected with the Redline malware as recently as May 20, 2026.

Why the Redline_Cloud4 Breach Is Dangerous

The Redline_Cloud4 log is labeled "fresh ULPP" (URL, login, password, profile), indicating credentials were recently harvested and organized by the specific sites where they were active. Each record contains an email address, a plaintext password, and the exact site URL, giving attackers a precise roadmap for immediate account access. With nearly 420,000 records, this dataset covers a substantial population of affected users.

Why This Redline_Cloud4 Data Puts You at Risk

Attackers who access this log can immediately test 418,487 email and password combinations against the sites listed in the data, as well as any other platform where victims reused those credentials. This enables account takeover across email, banking, and social media with minimal effort. The freshness of this dataset means many of the exposed credentials are likely still active, increasing the urgency to act if your data appears in this log.

How Stealer Logs Work

Redline malware is a credential-stealing tool sold and distributed on dark web forums. Once installed on a victim's device, it extracts saved browser passwords, autofill data, and session cookies, organizing the output into structured ULPP files that pair URLs with their associated login credentials. These files are then shared through Telegram channels like Redline_Cloud4, where threat actors distribute them as ready-to-use attack packages.
