The SunCloudNew 1329 LogsFile Means Someone Could Log Into Your Accounts

HEROIC analysts found a stealer log file uploaded to Telegram on November 7, 2025, labeled SunCloudNew 1329 - 700 LogsFile. The file contained 28,485 records pulled from compromised endpoint devices across the United States. Each record included an email address, a plaintext password, and a URL, data types that together give an attacker everything they need for immediate account access. This is a verified stealer log breach confirmed by our research team.

Why This Is Dangerous

This is not just a list of email addresses. Every record in this file includes the actual password typed by a real person, stored in plain text with no protection. An attacker with this file can walk into any account where that email and password combination is still active. API host URLs in the data also open doors to backend services that most people would never expect to be exposed.

What Was Exposed in the SunCloudNew 1329 Stealer Log

• Email Addresses
• Plaintext Passwords
• URLs and API Host Endpoints

Why This Matters for Your Security

Credential stuffing is the first thing attackers do with a file like this. They take the email and password pairs and automaticaly test them against popular services, banking apps, social media, email providers, and subscription platforms. If you reuse passwords, a breach from one service becomes a breach of every service. Financial fraud, identity theft, and account lockouts are all common outcomes when stealer log data gets into the wrong hands.

How Stealer Log Breaches Work

Stealer malware infects devices through fake downloads, phishing emails, or malicious ads. Once installed, it silently collects saved browser passwords, autofill data, and login sessions. The harvested data gets bundled into log files and sent to the attacker, who then sells or shares them on Telegram channels. Victiems never know it happened because the malware leaves no obvious trace. By the time an account gets compromised, the original infection may have occured weeks earlier.
