US Users Hit as SunCloudNew 1760-700 Leaks 4,108 Logins

HEROIC analysts found a stealer log file tied to SunCloudNew 1760-700, uploaded to a Telegram channel on 20 June 2026. The file contains 4,108 records, and the data trail points squarely to victims in the United States, each record pairing an email address, a plaintext password, and the site URL where that login was captured.

A US-Focused Leak: SunCloudNew 1760-700

While stealer logs can surface from anywhere, this batch appears concentrated among United States internet users. That regional pattern matters because attackers often tailor their next move to the country involved, targeting the banks, retailers, and tax services that people in that region actually use, which makes stolen US logins especially easy to weaponize.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites each login was used on

Why This Matters

Plaintext passwords need no cracking, so criminals can immediately try them across other accounts in a practice called credential stuffing. For US victims, that often means attempts against national banks, major retailers, and email providers. A successful login attempt can quickly turn into account takeover, followed by identity theft or financial fraud using stored card details.

How Stealer Log Malware Works

This type of malware typically arrives through a fake download, pirated software, or a malicious attachment. Once it runs, it quietly scans the browser for saved passwords and session cookies, then ships everything to a remote server controled by the attacker. The victim rarely notices anything until their accounts start acting strange.
