The SunCloudNew Leak: 467,185 Records Went Public Within Days

HEROIC analysts identified a large combolist called SunCloudNew 1793 - 607 K ULP uploaded by a Telegram User, shared on 05-Aug-2026, just days before this report. The file contains 467,185 records, pairing email or username with plaintext passwords and the URLs of the accounts each pair unlocks.

Why This Is Dangerous

This leak surfaced publicly only days after it was uploaded, which means the credentials inside it are almost certainly still active. With 467,185 plaintext email and password pairs already matched to specific site URLs, an attacker has a large, ready-made list they can start using immediately, with little time for anyone affected to change their passwords first.

What Was Exposed

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

Why This Matters

A combolist of nearly half a million records gives attackers enormous scale for automated credential stuffing attacks. If your email and password are among these 467,185 records, and you have used that same password anywhere else, attackers can move quickly from one exposed login to account takeover on your banking, email, or social media accounts, opening the door to financial fraud and identity theft.

How Combolists Work

A combolist, often labeled ULP for "URL, Login, Password," bundles stolen email addresses or usernames with matching passwords and the exact site each pair belongs to. These lists are usually assembled from older breaches, phishing pages, or stealer malware and then shared or sold on Telegram, where criminals can feed them straight into automated tools that test hundreds of thousands of logins in a short amount of time.

Check If You Are Affected

Because this leak went public so quickly after it was created, checking your exposure now matters more than usual. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, and tells you right away if you have been exposed. Run a free scan and change any reused passwords immediately.
