The SunCloudNew Log Leaked a Month Ago. 8,272 Passwords Are Public.

HEROIC analysts found a stealer log dataset labeled SunCloudNew 1780 - 550 LogsFile that was uploaded to a Telegram channel on July 17, 2026, roughly a month before this report. The file contains 8,272 records taken directly from infected devices, including email addresses, plaintext passwords, and the URLs of the login pages those credentials open. The gap between when data like this leaks and when it becomes widely known is exactly why waiting to check your exposure is risky.

Why This Stealer Log Is Dangerous

A month is more than enough time for a stealer log to circulate quietly among criminals before it becomes public knowledge. Every password in this file sits in plaintext, matched to the exact site it unlocks, with nothing standing in the way of an attacker who wants to use it. The longer a leak like this goes unnoticed, the more chances an attacker has had to act on it.

What Was Exposed in the SunCloudNew Stealer Log

• Email addresses tied to infected devices
• Plaintext passwords for those accounts
• URLs identifying the exact login pages the credentials belong to

Why This Matters for the 8,272 People Affected

With a month having already passed since this data leaked, some of these 8,272 accounts may already be compromised without their owners realizing it. If any of these people reused their password elsewhere, credential stuffing could extend the damage into email, banking, or shopping accounts. Account takeover and financial fraud become real risks the longer a working plaintext password like this sits unaddressed.

How Stealer Logs Like This One Get Created

Stealer log malware infects a device through fake downloads, cracked software, or malicious attachments. Once active, it silently harvests saved browser passwords, autofill data, and session information, then packages it into a log file sent back to the attacker. These logs are commonly traded or dumped in Telegram channels, exactly where HEROIC analysts found this one.

Check If You Are Affected

Do not let another month pass without knowing if you are one of the 8,272 people in this stealer log. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, so you can find out quickly and take action.
