672,402 Plaintext Passwords Dumped From SunCloudNew Logs

HEROIC has uncovered a massive stealer log dump labeled SunCloudNew 1775 - 811 K ULP shared on Telegram in July 2026. The file contains 672,402 stolen credential records — one of the larger individual dumps HEROIC has tracked. Every entry includes an email address, a plaintext password, and the URL where the credential was captured, creating an enormous dataset for automated account-takeover campaigns.

The Scale of Plaintext Password Exposure

At 672,402 records, this SunCloudNew dump represents a massive volume of immediately exploitable credentials. Every single password is stored as unencrypted, readable text. There is no hashing or salting to slow down attackers — each password can be used the instant the file is opened. The sheer scale means hundreds of thousands of individuals face direct account compromise.

What Was Exposed

• Email Addresses — hundreds of thousands of personal identifiers for account targeting
• Plaintext Passwords — over 672,000 unencrypted credentials ready for instant abuse
• URLs — the specific login endpoints where each password grants access

Mass Credential Stuffing at Unprecedented Scale

A dump of this magnitude supercharges credential-stuffing operations. Attackers feed hundreds of thousands of email-password pairs into automated tools that test them against banking, email, e-commerce, and enterprise platforms around the clock. With password reuse rates remaining stubbornly high across the internet, even a small percentage of successful matches from 672,402 records translates into thousands of compromised accounts.

Infostealer Malware: The Engine Behind Mass Credential Theft

Every record in this file represents a device that was compromised by infostealer malware. Programs like RedLine, Lumma, Vidar, and Raccoon Stealer spread through phishing campaigns, malvertising networks, and cracked software downloads. Once installed, they extract saved credentials from every browser on the system, capture authentication cookies and session tokens, and harvest autofill data. The stolen information is then aggregated into massive log file collections like this one and distributed through criminal Telegram networks.

Check If Your Credentials Were Exposed

HEROIC maintains a breach intelligence database with more than 400 billion compromised records from stealer logs, data breaches, and dark-web leaks. Given the enormous scale of this SunCloudNew dump, it is critical to check whether your credentials were included. Use the free HEROIC breach scanner to search for your email or password, and immediately update any compromised credentials across all services where they are used.
