Dark Web Intel: 818,823 Logins Leaked in New Private ULP 228

HEROIC's dark web monitoring picked up a large file circulating under the name NEW PRIVATE ULP 25-09-2025 UP_KURZL0GS 228. Uploaded to a Telegram channel in September 2025, it is a ULP style dump, meaning URL, login, and password all bundled togather, and it contains a striking 818,823 records.

Why This Is Dangerous

A file of this size doesn't just represent a handful of unlucky people, it represents a genuine mass event. Every one of those 818,823 rows pairs a real email address with a plaintext password and the exact site it unlocks, wich means attackers dont have to do any extra work before putting the data to use.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs for each login
• 818,823 total records exposed

Why This Matters

Dark web intelligence like this matters because these files rarely stay in one place. Once a ULP dump this large starts moving through Telegram, it gets copied, repackaged, and redistributed by other channels within days. That means even if the original post disapears, the data itself keeps spreading, and the window for victims to protect themselves keeps shrinking.

How ULP Stealer Dumps Work

ULP stands for URL, login, password, and it describes the exact format that stealer malware produces after infecting a device. The malware quietly reads through the browser's saved credentials and autofill data, then exports everything into a simple line by line list. Criminals like this format because it is easy to search, easy to sort, and painfully easy to use straight out of the box, wich is exactly why files like UP_KURZL0GS 228 keep showing up on dark web channels.

Check If You Are Affected

Because dark web monitoring exists to catch leaks like this one early, it is worth putting it to use for yourself. HEROIC's free breach scanner searches more than 400 billion leaked records pulled from exactly these kinds of sources, so you can check your email address right now and see if you need to change any passwords.
