The lionking_cloud Leak Exposed 33,562 US Cloud Accounts in a Stealer Log

In July 2025, a Telegram user shared a stealer log tied to lionking_cloud, exposing 33,562 records from United States-based cloud accounts. The dataset included email addresses, plaintext passwords, and the exact URLs of the cloud services each victim was using. For affected users, this breach did not just expose one password -- it handed attackers the direct path to cloud storage accounts, business tools, and every service tied to those credentials.

Why This Is Dangerous

Cloud account credentials are among the most valueable data a threat actor can obtain. Cloud storage accounts often hold backups of other passwords, financial documents, private communications, and authentication tokens for linked services. When an attacker has your cloud email, plaintext password, and the exact service URL, they can skip reconnaissance entirely and go straight to account acess. US-based cloud accounts are also disproportionately targeted because they are more likely to hold business data, financial records, and high-value personal information.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (direct links to cloud services and endpoints)

Why This Matters

With 33,562 US cloud account credentials in circulation, the scope of potential damage extends well beyond individual account takeovers. Business accounts can expose company data, client records, and internal communications. Personal cloud accounts can contain tax documents, ID scans, and other data useful for identity theft. The plaintext nature of the passwords means attackers face zero barriers to entry -- no cracking, no delay, no window for victims to respond before unauthorized acces occurs.

How Stealer Logs Work

Infostealer malware reaches US victims through targeted phishing campaigns, malicious software installers, and compromized browser extensions. Once installed on a device, the malware silently harvests stored passwords, session cookies, and credentials typed into web forms. US-based cloud services are heavily targeted because they tend to aggregate high volumes of sensitive data. The resulting log files are packaged and distributed through Telegram channels and dark web marketplaces where cybercriminals purchasse and deploy them for fraud and corporate espionage.
