If You Reuse Passwords, the SunCloudNew 1776 Leak Should Worry You

HEROIC identified a large-scale stealer log file labeled SunCloudNew 1776 - 500 K ULP circulating on Telegram as of July 2026. The dump contains 466,228 compromised credential records, each pairing an email address with a plaintext password and the URL where it was used. For anyone who reuses passwords across services, this leak poses an extraordinary risk.

Plaintext Passwords Are the Worst-Case Scenario

Every one of the 466,228 passwords in this file is stored as unencrypted, readable text. There is no hashing algorithm protecting them, no salting to complicate reversal. An attacker who accesses this SunCloudNew file can use any password immediately and without any tools. This is the most dangerous form of credential exposure possible.

What Was Exposed

• Email Addresses — the primary keys attackers use to target accounts across platforms
• Plaintext Passwords — nearly half a million unencrypted, directly usable credentials
• URLs — the specific services and login pages tied to each compromised credential

Password Reuse Makes You a Prime Target

If the same password protects your email, your bank account, and your Amazon profile, then one entry in this 466,228-record dump gives an attacker access to all three. Credential-stuffing tools automate this process, testing stolen pairs against thousands of websites in minutes. The mathematics are brutal: with this many records and typical reuse rates, tens of thousands of additional accounts will be compromised as a direct consequence of this single leak.

How Infostealer Malware Collected These Credentials

This data was not stolen from a single company’s database. It was harvested from hundreds of thousands of individual devices by infostealer malware. Programs like Lumma, StealC, and RedLine infect machines through phishing links, malicious ads, and pirated software. They silently export every saved password, browser cookie, and autofill entry from the victim’s system, then package the stolen data into log files that are sold and shared through criminal channels on Telegram and the dark web.

Check If Your Credentials Were Exposed

With a dump this large, the odds of your data being included increase significantly. HEROIC indexes over 400 billion compromised records from stealer logs, data breaches, and dark-web leaks. Use the free HEROIC breach scanner to find out if your email or password appears in the SunCloudNew 1776 dump or any other known compromise, and change every affected password immediately.
