How the SunCloudNew 1791 Leak Led to 444,212 Stolen Logins

HEROIC analysts found a combolist titled "SunCloudNew 1791 - 588 K ULP," uploaded by a Telegram user on August 3, 2026. The file contains 444,212 records pairing email addresses with plaintext passwords, along with the URLs of the sites those credentials were used on.

How the SunCloudNew 1791 Leak Led to 444,212 Stolen Logins

The ULP format used here means each of the 444,212 records bundles a URL, login, and password together, giving an attacker a ready-to-use set for each account. This is part of a numbered SunCloudNew series being pushed out on Telegram, and each entry in that series adds another batch of working credentials for buyers to test, which is how a single seller can end up circulating hundreds of thousands of stolen logins over time.

What Was Exposed in This Leak

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters for the 444,212 Accounts Involved

With 444,212 records now circulating, the odds that your email is included are significant. A working email and password pair lets an attacker attempt credential stuffing against your other accounts, since many people reuse passwords across email, banking, and social media. That is often how account takeover, identity theft, and financial fraud begin, from one exposed login rather than a dramatic hack.

How This Combolist Was Assembled

A combolist compiles login credentials, usually gathered through malware, phishing, or earlier breaches, into a single file. ULP-formatted lists like this one package the URL, login, and password together for each record, making the data easy to sort and use against specific websites. Numbered series like SunCloudNew suggest an ongoing operation, with each release adding fresh, working credentials to what has already been sold or shared.

Check If You Are Affected

With 444,212 records tied to this leak alone, checking your exposure is worth doing now. HEROIC's free breach scanner searches your email against a database of more than 400 billion leaked records, including combolists like SunCloudNew 1791, so you can find out if you are affected and secure your accounts before someone else uses your credentials.
