Search Your Email: The SunCloudNew 1790 Dump Exposed 331,034 Accounts

HEROIC analysts found a combolist titled "SunCloudNew 1790 - 403 K ULP," uploaded by a Telegram user on August 2, 2026. The file contains 331,034 records pairing email addresses with plaintext passwords, along with the URLs of the sites those credentials were used on.

Why the SunCloudNew 1790 Dump Is Dangerous

The "ULP" in the file's name is a common combolist format meaning URL, login, and password are all bundled together for each record. That combination is exactly what an attacker needs to log straight into an account without any extra work, since the plaintext password requires no cracking and the URL points directly to the correct site.

What Was Exposed in This Dump

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

Search Your Email: Why This Matters for the 331,034 Accounts Involved

With 331,034 records in circulation, the odds that your email address is included are worth taking seriously. Once an attacker has a working email and password pair, they can attempt credential stuffing against your other accounts, since so many people reuse the same password across email, banking, and social media. That single point of exposure is often how account takeover, identity theft, and financial fraud begin.

How This Combolist Was Assembled

A combolist compiles login credentials, typically gathered through malware infections, phishing pages, or earlier breaches, into a single file. ULP-formatted lists like SunCloudNew 1790 package each record with its URL, login, and password together, which makes the data easier for attackers to sort and target by website. Files like this are commonly traded and resold on Telegram, where buyers test the credentials in bulk looking for accounts that still work.
