US-Based MetaCloudVipNew 4050 PCs.part3 Stealer Log Breach

HEROIC analysts discovered the MetaCloudVipNew 4050 PCs.part3 stealer log in January 2026, uploaded by an anonymous Telegram user to a private threat-sharing channel. The file exposed 39,559 records, capturing endpoint credentials, email addresses, plaintext passwords, and API URLs harvested from comprimised Windows machines across the United States.

Why This Is Dangerous

Stealer logs combine multiple data points into a single exploitable package. Unlike a simple password list, this breach pairs email addresses with the exact URLs those credentials were used on, giving attackers a ready-made roadmap for account takeover without any guesswork. The passwords are stored in plaintext, meaning no cracking is requried before they can be put to use.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (site endpoints and API hosts)

Why This Matters

Credential stuffing attacks rely on exactly this kind of data. Attackers feed email and password combos into automated tools that test thousands of sites per minute. Because many people reuse passwords, a single stealer log can unlock banking portals, email accounts, and e-commerce profiles far beyond the original infection point. From there, identity theft and financial fraud become straightforward operations for even low-skill criminals who simply purchase the log data cheaply on underground markets.

How Stealer Log Breaches Work

Stealer logs are produced by infostealer malware, a catagory of malicious software typically delivered through phishing emails, fake software downloads, or malicious browser extensions. Once installed on a victim's device, the malware silently harvests saved browser credentials, cookies, and autofill data before packaging everything into a compressed log file. That file is then uploaded to Telegram channels or dark web forums where other criminals can download and abuse it. The original device owner often has no idea anything was stolen until their accounts start getting compromised.
