U.S. Users Hit: Dragon Private Cloud Exposes 16,232 Passwords

HEROIC has flagged a significant stealer log dump labeled Dragon Private Cloud TG ArhontCorp circulating on Telegram since July 2026. The dataset contains 16,232 records primarily affecting users in the United States, with each entry exposing an email address, a plaintext password, and the associated login URL in a ready-to-exploit format.

Plaintext Passwords: Zero Barrier to Account Takeover

All 16,232 passwords in the Dragon Private Cloud file are stored as unencrypted plain text. Unlike hashed passwords that require computational resources to reverse, these credentials are immediately usable. Any person who accesses this file can log into victim accounts without any tools, expertise, or delay.

What Was Exposed

• Email Addresses — personal account identifiers enabling both direct access and phishing attacks
• Plaintext Passwords — unencrypted login credentials with no protection whatsoever
• URLs — the exact web services and applications where each credential was captured

Why Credential Stuffing Makes Every Reused Password a Liability

With over 16,000 email-password pairs at their disposal, attackers can mount devastating credential-stuffing campaigns. Automated scripts test each combination against popular services — email providers, financial platforms, e-commerce sites, and cloud storage — looking for matches. Since most users employ the same password on multiple sites, one compromised record from this Dragon Private Cloud dump can unlock an entire chain of accounts.

Infostealer Malware: The Source of This Data

The records in this file were collected by infostealer malware operating on compromised devices. Malware families like RedLine, Raccoon, and Vidar spread through phishing emails, fake software cracks, and malicious browser extensions. They silently extract saved login credentials, session cookies, cryptocurrency wallet data, and browser autofill information. The stolen data is then compiled into structured stealer logs and shared or sold through underground Telegram networks.
