OnlyLogs Cloud Stealer Log Exposes 21,096 Multi-Industry Logins

In January 2026, HEROIC identified 21,096 records from a stealer log file uploaded to Telegram by an anonymous user as part of the OnlyLogs - OnlyLogsCloud collection. The data was shared publicly and contained email addresses, plaintext passwords, and URLs associated with compromised endpoints.

Why the OnlyLogs Cloud Stealer Log Is Dangerous

Credentials in this log were captured live at the moment of login by infostealer malware -- no cracking required. Unlike hashed password dumps, these email addresses and passwords are immediately usable by attackers on any service where victims reused their credentials.

What Was Exposed in the OnlyLogs - OnlyLogsCloud Leak

• Email addresses
• Plaintext passwords
• URLs of compromised endpoints

Why This OnlyLogs Cloud Data Puts You at Risk

The URLs in this log map attackers directly to specific accounts -- each URL reveals exactly which service the victim was logged into when their credentials were captured. With 21,096 records spanning multiple industries and services, the log provides attackers with a broad range of entry points across banking, e-commerce, workplace, and personal platforms. Distribution through Telegram multiplies the exposure across thousands of threat actors simultaneously.

How Stealer Log Breaches Work

Infostealer malware is typically delivered via phishing emails or malicious downloads. Once installed, it hooks into your browser's saved passwords and captures email addresses, passwords, and the URLs of sites you log into. These credentials are packaged into a log file and uploaded to command-and-control servers, then redistributed through Telegram channels to other cybercriminals.
