SunCloudNew Breach: 76,442 Cloud Passwords Leaked

HEROIC analysts uncovered a stealer log named "SunCloudNew 1324 - 386 K ULP" uploaded to Telegram on 01-Nov-2025. The file contains 76,442 records, each combining an email address, a plaintext password, and the URL of the site that login belongs to. A closer look at the URLs inside shows a heavy mix of cloud storage and SaaS style logins, making this leak especially relevant to anyone using cloud-based tools for work or personal storage.

Why This Is Dangerous

Cloud accounts often hold far more than a single password. They connect to file storage, backup services, and sometimes billing information. Because the passwords in this log are stored in plaintext, an attacker can log directly into these cloud accounts without any extra effort and start looking through whatever is stored inside.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why Cloud and SaaS Accounts Are a Prime Target

Cloud storage and software-as-a-service accounts are attractive to attackers because a single login often unlocks documents, photos, contact lists, and connected apps all at once. Small businesses that rely on cloud tools for invoicing, file sharing, or customer records are particularly exposed if an employee's personal password habits carry over into work accounts.

Attackers who specialize in this vertical often resell access to cloud accounts separately from the raw credential list, since a working cloud login can be worth more than the password alone. That makes leaks like this one a magnet for a specific type of buyer.

Why This Matters

If any of these cloud credentials are reused elsewhere, the risk expands into credential stuffing against banking and email accounts too. The combination of stored files and reused passwords creates a path toward account takeover, data theft, and even financial fraud if payment details are linked to the affected cloud service.

How This Stealer Log Happened

Like most stealer logs, this one traces back to malware installed through cracked software or deceptive downloads. Once active, it quitely collects saved logins, including cloud service credentials, and packages them for sale or free distribution on Telegram.

Check If You Are Affected

If you use cloud storage or SaaS tools for work or personal files, it is worth checking this leak specifically. HEROIC's free breach scanner searches more than 400 billion compromised records and tells you right away if your email appears in this file or any other leak circulating on the dark web.
