57,135 Records Exposed in the SunCloudNew Stealer Log Leak

57,135. That's the exact number of records sitting inside a stealer log called "SunCloudNew 1330 - 320 K ULP," uploaded to Telegram in November 2025. Despite the "320 K" in the file's name, hinting at a bigger batch it may have been pulled from, the confirmed record count for this specific leak comes in at 57,135 exposed credentials.

Why This Is Dangerous

Over fifty thousand email and password pairs is more than enough for attackers to run a serious credential-stuffing campaign. They don't need to guess anything, thier scripts simply feed in each pair and see which ones still work across popular sites like email providers, banks, and online stores.

What Was Exposed

• Email addresses tied to real accounts
• Plaintext passwords with no encryption
• URLs showing the exact services affected
• 57,135 total records confirmed in this leak

Why This Matters

Files like this one often get pulled from a larger, seperate batch and repackaged into smaller chunks for easier distribution and sale. That means the same underlying data might show up again later under a different name, so checking now matters even if you think you've already dodged a related leak. Anyone affected should imediately treat the exposed password as compromised.

How Stealer Logs Work

ULP files like this one are compiled from stealer malware that infects devices and copies saved browser credentials without the user's knowledge. The "1330" and "320 K" in the file name likely reference an internal batch or version number used by whoever is distributing these logs, suggesting this leak is part of a much larger ongoing operation.
