CLOUD4LOGS Leak Leaves 24,770 Accounts Open to Takeover

HEROIC analysts identified a stealer log file titled "CLOUD4LOGS 1000 GMAIL VALID" uploaded to a Telegram channel on January 10, 2023, exposing 24,770 records harvested from compromised endpoints. The dataset includes email addresses, plaintext passwords, and URLs pulled directly from infected devices.

Why This Is Dangerous

The passwords in this log were captured in plaintext, exactly as the victims typed them, and paired with the exact URLs those credentials unlock. That combination gives anyone who obtains the file a working login list with no cracking or guessing needed, leaving thousands of accounts open to immediate takeover.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to the compromised accounts

Why This Matters

At nearly 25,000 records, this is a large enough set to fuel automated credential stuffing attacks, where stolen logins are tested against banking, email, and shopping sites in bulk. Anyone who reused a password across accounts risks account takeover, phishing, and identity theft.

How Stealer Log Breaches Happen

Stealer logs come from malware quietly installed on a victim's device, often through a pirated download, a cracked application, or a malicious attachment. Once active, the malware scrapes saved browser passwords, autofill details, and session data, then bundles everything into a single log file. Criminals package logs like this one, labeled CLOUD4LOGS, and circulate them through Telegram channels and dark web forums, where a single upload can expose tens of thousands of accounts at once.
