The Rogue Cloud TG RogueCloud Leak Contains More Records Than the Population of Kalamazoo

HEROIC analysts identified this stealer log after a Telegram user uploaded it in February 2026. The file contains 17,865 records with email addresses, plaintext passwords, and URLs harvested from infected devices by malware operating without the victims knowledge.

Why Rogue Cloud TG RogueCloud uploaded by a Telegram User Is Dangerous

The Rogue Cloud TG RogueCloud dataset is dangerous because it contains ready-to-use login credentials that require no additional processing. Passwords are stored in plaintext, so anyone who downloads the file can begin testing those credentials against popular websites right away. The fact that this file was shared on Telegram means it has likely already been downloaded and redistributed by multiple threat actors.

What Was Exposed in Rogue Cloud TG RogueCloud uploaded by a Telegram User

• Email Addresses
• Plaintext Passwords
• URLs (websites the victim was logged into)

Why This Matters

Exposed email and password pairs fuel credential stuffing attacks, where automated tools test the same login details across hundreds of websites simultaneously. Successful attempts lead to account takeover, which can result in identity theft, unauthorized purchases, and financial fraud. Because most people reuse passwords, a single exposed credential can compromise multiple accounts at once. The damage from one stealer log can spread far beyond the original source.

How Stealer Log Works

Stealer logs are created by infostealer malware that secretly installs itself on a victims computer, often through a malicious email attachment or a fake software download. The malware then scans the device for saved browser passwords, active sessions, and login cookies. All of this data is bundled into a log file and transmited back to the attacker. The attacker may then upload the file to Telegram or dark web forums where others can freely download and exploit the credentials.
