HEROIC Analysts Track SunCloudNew Leak of 18,002 Records

HEROIC analysts tracked a stealer log file labeled "SunCloudNew 1282" uploaded to a public Telegram channel on September 10, 2025. The file contained 18,002 records taken directly from infected devices, each combining an email address with a plaintext password and the URL of the account it opens.

Why This Is Dangerous

Because these passwords were stored in plaintext, an attacker can use them the moment the file is downloaded, with no cracking or guessing required. Each record already links a specific email, password, and website, handing criminals a ready-made list of working logins.

What Was Exposed

• 18,002 individual records
• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Everyone in this log faces immediate account takeover risk, plus credential stuffing risk on any other service where the same password was reused. A single compromised login can cascade into email takeover, financial fraud, and identity theft as attackers work through connected accounts.

How Stealer Log Breaches Work

Stealer log malware infects a device through a fake download, cracked software, or a malicious attachment, then silently harvests saved browser passwords, autofill data, and session cookies. The malware ships the results back to the attacker, who bundles them, like this 18,002-record SunCloudNew file, and distributes them through Telegram channels and dark web marketplaces.
