Dark Web Intel: Nullcyber Cloud ULP Leak Exposes 423,338 Accounts

Dark web intel gathered by HEROIC's monitoring systems flagged a stealer log titled ULP_Private_1166431_071125_034158_Nullcyber_Cloud shortly after it was uploaded to Telegram on November 7, 2025. The file holds 423,338 records made up of email addresses, plaintext passwords, and URLs, and our team moved to document it right away.

Why This Is Dangerous

The name of this file alone hints at how organized the group behind it is, complete with timestamps and internal labeling that suggest a somewhat proffesional operation rather than a random one off dump. Files this organized often mean the person distributing it has done this before and knows exactly how to package data for maximum resale value.

What Was Exposed

• Email addresses tied to individual accounts
• Plaintext passwords with no encryption applied
• URLs identifying the exact services affected
• 423,338 total records confirmed in the file

Why This Matters

Dark web intel like this matters because it gives defenders a head start. Instead of waiting for stolen credentials to be used in an actual attack, HEROIC's team can identify the leak, asses its scope, and alert people before the damage spreads further. That head start is often the only real advantage people have against organized credential theft.

How Stealer Logs Work

Every stealer log traces back to malware that infected a real device, quietly extracting saved browser passwords, cookies, and autofill information before sending it off to a remote server. From there, the data gets sorted, labeled, and eventually distributed, which is exactly the kind of organized process reflected in this file's detailed name.

Check If You Are Affected

Acting on dark web intel starts with checking your own exposure. HEROIC's free breach scanner searches more than 400 billion leaked records gathered from stealer logs and breaches across the dark web, giving you a clear, fast answer about whether your email was part of this leak.
