The SunCloudNew 1789 Stealer Log Could Expose 4,659 Accounts

HEROIC analysts found a stealer log package called "SunCloudNew 1789 - 500 LogsFile," uploaded by a Telegram user on August 1, 2026. The file contains 4,659 records, including email addresses, plaintext passwords, and the URLs or API hosts those credentials were tied to, all pulled from infected devices.

Why the SunCloudNew 1789 Stealer Log Is Dangerous

This log means someone could already be logging into accounts belonging to the 4,659 people in this file. Because the passwords are stored in plaintext and paired with the exact URL each one unlocks, an attacker does not need to guess anything, they can simply pick a record and try the login right away, on your email, a shopping account, or anything else tied to that credential.

What Was Exposed in This Stealer Log

• Email addresses
• Plaintext passwords
• URLs and login endpoints tied to each credential

Why This Matters for the 4,659 Accounts Involved

If your credentials are among these 4,659 records, it means malware ran on a device you used and captured a working login. Since many people reuse the same password across multiple sites, that single stolen credential can lead to credential stuffing against your other accounts, opening the door to account takeover, identity theft, or financial fraud.

How Stealer Logs Like SunCloudNew 1789 Are Built

Stealer log malware infects a device, often through a fake download, cracked software, or a phishing link, then quietly collects saved passwords, browser autofill data, and login sessions before sending everything to the attacker. The "500 LogsFile" naming suggests this collection is one part of a larger series being distributed on Telegram, where sellers package infected logs into numbered batches like this one for buyers looking for fresh, working credentials.

Check If You Are Affected
