How Infostealer Malware Exposed 16,642 SunCloudNew Credentials

In January 2026, HEROIC identified 16,642 records from a stealer log file uploaded to Telegram by an anonymous user under the name SunCloudNew 1369 - 650 LogsFile. The data was shared publicly and contained email addresses, plaintext passwords, and URLs associated with compromised endpoints.

Why the SunCloudNew 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 SunCloudNew 1369 - 650 LogsFile Leak

• Email addresses
• Plaintext passwords
• URLs of compromised endpoints

Why This SunCloudNew 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. Distribution through Telegram multiplies the exposure across thousands of threat actors simultaneously, meaning multiple parties may have already attempted to exploit these credentials.

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.
