US-Linked Telegram Stealer Leak Exposes 33,855,820 Records

Its rare to see a stealer log reach the scale of this one. Uploaded to Telegram in October 2025 under the label Premium NEW FRESH DATABASE URL UP_KURZL0G, this dump carries a staggering 33,855,820 records tied largely to users in the United States. Thats not a typo, its over 33 million individual login combinations sitting in a single file that anyone on the channel could download for free.

Why This Is Dangerous

Size changes everything with a leak like this. A file this large gets picked up by automated tools within hours, cross referenced against other databases, and fed into credential stuffing scripts that test logins across hundreds of websites at once. Because the passwords are stored in plaintext, there is no encryption to slow attackers down, they can use the data the moment they recieve it.

What Was Exposed

Analysts confirmed the following data types inside this record set:

• Email Addresses
• Plaintext Passwords
• URLs linked to each login
• 33,855,820 total records exposed

Why This Matters

A leak of this size doesnt stay contained to one group of criminals for long. Once a file labeled Premium and Fresh starts circulating on Telegram, it gets copied, resold, and mirrored across other channels and forums seperate from where it first appeared. That means the real number of people who eventually gain access to these 33 million plus records is likely much higher than the original upload alone suggests.

How Stealer Logs Work

Stealer logs like this one come from malware that infects a device and quietly copies saved browser passwords, autofill fields, and session data before sending it all back to the attacker. Because so many people reuse the same device across work, banking, and personal accounts, one infection can produce dozens of usable credential pairs, which is how a single malware campaign can snowball into tens of millions of exposed records.
