BlackHat_Cloud 372 Dump Put Cloud Data for 1.1 Million Users on the Dark Web

HEROIC analysts flagged the BlackHat_Cloud 372 stealer log after it appeared in a Telegram distribution channel in July 2025. The archive contained 1,158,730 records pulled from infected devices, with each entry including a plaintext password, email address, and the URL of the service where the credential was used. The dataset was verified by our breach intelligence team and confirmed to contain active, recently harvested credentials primarily tied to United States-based users and cloud service accounts.

Why This Is Dangerous

A stealer log with over one million plaintext passwords is not a historical curiosity -- it is a live attack resource. Every record in this file represents a real person who had malware running on their device without knowing it. The URLs in the BlackHat_Cloud 372 log show exactly which cloud platforms, email services, and web applications the victims were using. Attackers do not have to guess where to try the stolen passwords. They already know. Credential stuffing tools can cycle through a million login attempts across dozens of services in a matter of hours.

What the BlackHat_Cloud 372 Stealer Log Exposed

Each of the 1,158,730 compromised records in this dataset contained the following information:

• Email addresses (the primary login identifier for most online accounts)
• Plaintext passwords (captured directly from the victim's device, unencripted and immediately usable)
• URLs (the exact web addresses where each credential was harvested, including cloud portals and API enpoints)

Why the BlackHat_Cloud 372 Breach Puts Cloud and Tech Users at Elevated Risk

The name "BlackHat_Cloud" and the structure of the URL data in this log suggest a heavy concentration of cloud service credentials -- think platform logins, developer tools, SaaS accounts, and business email. For organizations, this is especially alarming. A single compromised employee credential can give an attacker access to shared drives, internal communications, customer data, and code repositories. Cloud account takeover is one of the fastest-growing categories of business fraud. Even individual users face serious consequences: cloud storage accounts often hold sensitive personal files, tax documents, and identity information that can fuel identity theft or extortion. With 1.1 million records in circulation, the volume alone increases the odds that your accounts are in this file.

How Stealer Log Malware Targets Cloud Credentials

Information stealer malware is specifically designed to capture the kinds of credentials that matter most to criminals. When a device is infected -- through a phishing link, a fake software installer, or a malicious browser extention -- the malware immediately begins harvesting saved passwords from the browser, session cookies, and any credentials the user types. Cloud service logins are a priority target because they often unlock additional resources and contacts. The BlackHat_Cloud 372 log is the output of this process at scale: hundreds of thousands of infected devices silently reporting credentials back to a central server before the data is packaged and sold through Telegram channels. The 372 in the file name likely indicates this is one installment in an ongoing series of log releases from the same threat actor.

Check If Your Cloud Accounts Were Exposed in This Breach

With over one million records in the BlackHat_Cloud 372 log, the chances that someone you know appears in this dataset are significant. HEROIC offers a free breach search powered by a database of over 400 billion compromised records. Enter your email address to find out if your credentials appeared in this breach or any of the thousands of others in our index. If you find a match, change your passwords immediately -- especially on any cloud services, email accounts, or platforms where you store sensitive data -- and turn on two-factor authentication right away.
