ROG ULP Stealer Log Breach Exposes 7M+ Login Credentials

HEROIC analysts identified a stealer log dataset uploaded to Telegram on November 3, 2025, exposing 7,084,678 records. The file was posted by a Telegram user distributing logs pulled directly from malware-infected devices, and it contains email addresses, plaintext passwords, and the URLs of the websites those credentials unlock.

Why This Stealer Log Is Dangerous

Unlike a typical company data breach, a stealer log comes straight from a victim's own computer. Malware silently copied saved logins from browsers and apps, then packaged them into a neat, ready-to-use list. Because the passwords are stored in plaintext and paired with the exact login URL, an attacker doesn't need to guess or decrypt anything. They can simply open the file and start signing in.

What Was Exposed in This Stealer Log

• Email addresses
• Plaintext passwords
• Login URLs tied to each credential pair

Why This Matters for Anyone Reusing Passwords

Stealer logs are a favorite tool for credential stuffing attacks, where criminals feed thousands of email and password combos into automated scripts and test them against banking sites, email providers, and social media platforms. If you reuse a password across multiple accounts, one infected device can lead to a full chain reaction of account takeover, identity theft, and financial fraud.

How Stealer Log Breaches Actually Happen

Stealer malware, sometimes called an info-stealer, infects a device through a fake software download, a cracked game file, or a malicious email attachment. Once installed, it quitely scans the browser's saved password vault, autofill data, and session cookies, then uploads everything to the attacker's server. The stolen data is often reformatted into a "log" and sold or shared in bulk on Telegram channels and dark web forums, exactly like the file behind this incident.
