The MetaCloudVipNew Stealer Log Means Someone Could Access Your Accounts

HEROIC analysts flagged a stealer log file uploaded to Telegram in March 2026 by a threat actor operating under the name MetaCloudVipNew. The file, labeled as data harvested from 3,850 infected PCs, contained 10,463 records. Each record included an email address, a plaintext password, and the URL of the site where that credential was used. This is not a breach of one company's database. It is data silently stolen from thousands of individual users' devices before being packaged and shared publicly on Telegram.

The MetaCloudVipNew Log Means Someone Could Be Logging Into Your Accounts Right Now

Stealer log data is prized by attackers because it is already organized for action. Each entry in this file tells a threat actor: here is the email, here is the password, here is exactly where it works. There is no guesswork involved. With 10,463 sets of credentials tied to specific URLs, anyone who downloads this file can immediately attempt logins on the exact sites listed. Banking portals, email providers, cloud storage, and business apps are all represented. The window between a log file appearing on Telegram and the first attempted logins is often measured in hours.

What Was Exposed in This Leak

• Email Addresses
• Plaintext Passwords
• URLs (the exact sites where credentials were active)

Why This Matters for Credential Theft and Account Takeover

This type of data does not sit idle. Stealer log files shared on Telegram are downloaded by dozens or hundreds of actors within days of posting. They feed into credential stuffing campaigns where automated tools attempt logins at scale across major platforms. Because the passwords are plaintext and matched to their originating URLs, bypass rates are significantly higher than with cracked or guessed passwords. Victims often discover unauthorized access only after noticing fraudulent transactions, locked accounts, or data they did not share showing up elsewhere.

How Telegram-Distributed Stealer Logs Work

Stealer malware infects devices through phishing links, trojanized software downloads, and malicious browser extensions. Once active, it harvests credentials stored in browsers and apps, captures session cookies, and records the URLs associated with each saved login. The resulting log files are organized by infected machine and uploaded to Telegram channels where they are shared freely or sold. The MetaCloudVipNew label suggests an actor who runs or distributes MetaStealer-family malware, collecting logs from a fleet of compromised endpoints before packaging them for release. The 3,850 PCs figure indicates the scope of the underlying infection campaign behind this single file.
