SunCloudNew ULP Combolist Leak: 65,156 Login Credentials Exposed

Let's start with the basics: a combolist is just a giant list of username-and-password pairs, and SunCloudNew 1305 - 339 K ULP is a fresh one, uploaded to Telegram on 04-Oct-2025 with 65,156 credential pairs inside.

Why This Is Dangerous

Combolists like this one are the raw fuel behind something called credential stuffing, wich is when attackers take a giant list of email-and-password pairs and test them, automatically, against hundreds of other websites. If even a small percentage of these 65,156 accounts reused their password somewhere else, that is definately enough for attackers to break into banking, shopping, or email accounts at scale.

What Was Exposed

• 65,156 individual records
• Email Addresses
• Plaintext Password
• URLs

Why This Matters

The term ULP stands for URL, Login, Password, three pieces of information listed together on one line. That format makes it trivially easy for even an unskilled attacker to load the file into automated tools and start testing logins within minutes of the leak going live.

How a Combolist Stealer Log Works

This kind of file is built by combining data pulled from multiple infected devices, sometimes from a single stealer campaign, sometimes stitched together from several. Once the harvesting occured, the operator behind it sorted the stolen data into the ULP format and released it through Telegram, where it can be downloaded by anyone with a link.

Check If You Are Affected

You shouldn't have to wonder whether your credentials are floating around in a combolist. HEROIC's free breach scanner cross-references your email against more than 400 billion leaked records and will tell you immediately if you need to change a password.
