MetaCloudVipNew Stealer Log: 20,830 Plaintext Passwords Hit Telegram

In March 2026, HEROIC analysts identified a stealer log file circulating on Telegram that exposed 20,830 records tied to real endpoint devices. The file, uploaded by an anonymous Telegram user under the label "MetaCloudVipNew 4200 PCs.part2," contained email addresses, plaintext passwords, and URLs harvested directly from infected machines. This is the kind of data that doesn't sit idle on the dark web for long.

Why Stolen Endpoint Data Is More Dangerous Than a Simple Password Leak

Most people think of a data breach as someone getting their email and password. Stealer log data goes further. Because this data was pulled from live machines using malware, it reflects exactly what a victim was doing at the time of infection: which sites they were logged into, what credentials they used, and which URLs they visited. An attacker with this data doesn't need to guess. They already know.

Plaintext passwords are especially damaging because they require no cracking. They are ready to use the moment the file is opened. Combined with the associated email addresses and URLs, an attacker can prioritize which accounts to hit first based on value.

What Was Exposed in the MetaCloudVipNew Stealer Log

• Email Addresses: Full email accounts linked to infected devices, used to identify and target victims across platforms.
• Plaintext Passwords: Unencrypted, ready-to-use credentials harvested directly from browser storage or active sessions.
• URLs: The specific websites where credentials were captured, revealing which services and accounts are at risk.

Why This Stealer Log Matters Beyond the 20,830 Records

Twenty thousand records may not sound like a massive breach compared to some of the multi-billion record dumps that have surfaced in recent years. But stealer log data is qualitatively different. These are not recycled credentials from a years-old database. They were pulled from active, compromised machines in early 2026, which means the accounts they reference are likely still live and in use.

Credential stuffing attacks rely on exactly this kind of fresh data. Attackers load stealer log credentials into automated tools and test them against banking portals, email providers, and e-commerce platforms. If you reuse passwords across sites, a single infected device can expose dozens of accounts simultaneously. Identity theft, unauthorized purchases, and account takeover are all real outcomes when this data reaches the wrong hands. It is definitly not something to dismiss because of the record count.

How Stealer Log Malware Works: From Infection to Dark Web Sale

Stealer logs are the output of a specific category of malware called information stealers. Popular variants include RedLine, Raccoon, and MetaStealer. These programs are typically distributed through phishing emails, cracked software downloads, or malicious browser extensions. Once installed on a device, they silently scan for saved passwords in browsers like Chrome and Firefox, extract active session cookies, and record URLs of recently visited sites.

The harvested data is then bundled into log files and either sold directly to buyers or uploaded to Telegram channels where they are shared freely or auctioned off. The "4200 PCs" label in this file's name suggests it was compiled from approximately 4,200 infected endpoints before being split into parts and distributed. The fact that this particular file reached public circulation means the data has been accessable to threat actors for weeks or months.

Check If Your Credentials Appeared in This Stealer Log

HEROIC's breach scanner checks your email address against a database of over 400 billion exposed records, including stealer log data like this file. If your credentials were captured by the MetaCloudVipNew malware campaign, the scanner will flag it immediately.

A free scan takes less than a minute. If you show up in this or any other breach, HEROIC will show you exactly which data was exposed so you can take action before an attacker does. Don't wait to find out the hard way that your account was already compromised.
