Inside MetaCloudVipNew Part 1: How Infostealer Malware Harvested 26,487 Passwords

HEROIC analysts uncovered the MetaCloudVipNew 3600 PCs.part1 stealer log in February 2026, when a Telegram user shared a dataset containing 26,487 compromised records. The data was collected from 3,600 infected computers and contained email addresses, plaintext passwords, and URLs harvested from victims' browsers. This part of a larger stealer log collection represents thousands of individuals whose devices were silently compromised by infostealer malware.

Why This Is Dangerous

With nearly 26,500 records exposed in just one part of this dataset, the scale of this breach is significant. Attackers who download and use this log gain immediate access to working plaintext credentials and a detailed list of the websites each victim frequents. This allows for highly targeted account takeover attempts with no guesswork required. The recency of this breach, from February 2026, means many of these passwords are likely still active and have not yet been changed by victims who remain unaware of the exposure.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (websites and services accessed by victims)

Why This Matters

Credential stuffing attacks powered by fresh stealer logs like this one are among the most effective tools in a cybercriminal's arsenal. Because victims are unaware their credentials were stolen, they continue using compromised passwords. Attackers exploit this window to access bank accounts, email inboxes, social media profiles, and workplace systems before any warning is recieved. This type of breach also fuels downstream identity theft and financial fraud at scale.

How Stealer Logs Work

Infostealer malware is typically delivered through phishing emails, malicious downloads, or compromised software installers. Once it runs on a device, it immediately begins harvesting saved passwords from browsers like Chrome, Firefox, and Edge, along with cookies, session tokens, and a list of visited websites. All collected data is packaged into a structured log file and sent back to the attacker. These logs are then sold in bulk or shared freely on Telegram channels and dark web forums, where they are accessed by multiple threat actors. The MetaCloudVipNew collection, spanning thousands of PCs, illustrates how industrialized and scalable this type of data theft has definately become.

Check If You Are Affected

Because this breach occured in early 2026, affected individuals may still be using compromised passwords right now. HEROIC's free breach scanner searches more than 400 billion records in the DarkHive database, including the MetaCloudVipNew dataset. Enter your email address to find out whether your credentials have been exposed. Early detection is the most effective way to prevent account takeover and minimize the damage from infostealer attacks.
