How a Stealer Log Exposed 3,033 SunCloudNew Account Passwords

In August 2026, HEROIC analysts identified a stealer log file named "SunCloudNew 1792 - 550 LogsFile" uploaded to a Telegram channel by an anonymous user. The file contained 3,033 records made up of email addresses, plaintext passwords, and the URLs of the sites those credentials unlock.

Why the SunCloudNew Leak Is Dangerous

Stealer logs like this one are not stolen from a company's database. They are the direct output of malware that infected a computer, quietly copied every password saved in the browser, and matched each one to the exact site it unlocks. Whoever holds this file can log in immediately without cracking or guessing anything.

What Was Exposed in the SunCloudNew File

• Email addresses
• Plaintext passwords
• The URLs of the websites those logins belong to

Why This Matters

Because the passwords are plaintext and already matched to working login pages, this data is ready to use for account takeover the moment it changes hands. Anyone in this file risks having their email, shopping, or social accounts accessed by someone else, especially if that password has been reused anywhere.

How Stealer Logs Work

A stealer log begins with information-stealing malware, often hidden inside a cracked program, fake software update, or malicious attachment. Once it runs on a victim's device, it reads the passwords saved in the browser, along with autofill data and session cookies, and sends everything back to the attacker in one file. That file, like "SunCloudNew 1792 - 550 LogsFile," is then packaged and shared or sold on Telegram, which is how this one surfaced.

Check If You Are Affected

You don't need to guess whether your information is part of a leak like this one. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs and combolists like this, and tells you right away if your credentials have been exposed.
