6793 Records from Universe Logs 400 Cloud Logs Telegram User Leaked in Stealer Log Attack

In November 2025, a Telegram user uploaded a stealer log labeled "Universe_Logs 400 Cloud Logs" to a public channel, exposing 6,793 records pulled from infected devices in the United States. HEROIC analysts reviewing the file found that each record includes an email address, a plaintext password, and a URL identifying the associated service. The "Cloud Logs" wording in the file's name is the uploader's own label for this batch, reflecting that many of the captured credentials were tied to cloud-based accounts.

Why This Is Dangerous

Cloud account credentials are especially valuable because a single login can open access to storage, files, and connected applications all at once, rather than just one isolated service. Because the passwords in this file are stored in plaintext, no cracking is required, so anyone who downloaded the file could begin using the credentials immediately.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated service URLs

Why This Matters

Even though this file contains fewer records than some other stealer logs, cloud-focused credentials can carry outsized risk since a single compromised login may grant access to far more than a typical website account. Because this file was posted publicly rather than sold, it was available to anyone watching the channel almost as soon as it went live.

How Stealer Logs Work

Infostealer malware typically spreads through phishing emails, malicious software bundles, or compromised browser extensions. Once active on a device, it harvests saved credentials from browsers and packages what it finds into a structured log file, sometimes grouped by the type of service the credentials belong to, which is likely how this batch came to be labeled around cloud accounts.

After collection, logs like this one are shared or sold on Telegram and similar channels, and once downloaded by others, they become effectively impossible to remove from circulation.
