How a Stealer Log Called KepperCkoud 1152 Led to 10,749 Stolen Logins

HEROIC analysts identified a stealer log labeled "KepperCkoud 1152" uploaded to a Telegram channel on December 24, 2022. The file contained 10,749 records, each pairing an email address with a plaintext password and the URL of the site the login belonged to. That structure, credentials tied directly to the service they unlocked, is the fingerprint of infostealer malware pulling saved logins off infected devices.

How KepperCkoud 1152 Led to Stolen Logins

The path from infection to stolen login is short with this kind of data. Infostealer malware on an infected device quietly copies every saved password and the site it belongs to, then sends that file back to whoever controls the malware. Once packaged and shared, as this log was on Telegram, anyone who obtains the file has 10,749 ready-to-use logins, no cracking or guessing required because the passwords are stored in plaintext.

What Was Exposed in the KepperCkoud 1152 Log

• Email addresses
• Plaintext passwords
• URLs of the associated login pages or services

In total, 10,749 records were included in the file.

Why This Matters

A dataset of this size is exactly the kind of raw material used in credential stuffing campaigns, where stolen email and password pairs are tested automatically across thousands of other sites. Because each record already ties a password to the exact service it opened, it also speeds up account takeover for anyone who reused that password elsewhere, extending the risk to financial fraud and identity theft.

How a Stealer Log Like This Gets Built

Infostealer malware infects a device, harvests saved browser passwords and the URLs tied to them, and sends everything back to the attacker controlling it. A log of nearly 11,000 records suggests credentials were gathered from many infected machines before being compiled and shared under a label like KepperCkoud. These consolidated logs are routinely traded or resold in underground Telegram channels and dark web forums, which is how one infostealer campaign becomes a widely circulated dataset even years later.

Check If You Are Affected

With nearly 11,000 accounts in this single log, the odds that your information is included are real. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like this one, so you can see what has been exposed and change any reused passwords before someone else does.
