15,815 Stolen Credentials From MetaCloudVipNew 4000 PCs.part3 Surface on Telegram

In February 2026, HEROIC analysts identified a stealer log collection shared on Telegram under the name MetaCloudVipNew 4000 PCs.part3. The file name itself tells a story: 4000 PCs refers to the number of infected computers from which credentials were harvested, and part3 indicates this is the third segment of a larger campaign. The file exposed 15,815 records, each containing an email address, a plaintext password, and the URL of the specific site the credential belongs to. This is not a historical breach. It is a recent, active data leak from early 2026.

Why 15,815 Plaintext Passwords From MetaCloudVipNew Are an Immediate Threat

The scale and recency of this breach make it particulary concerning. With 15,815 records all containing unencrypted passwords, attackers have a large, ready-to-use credential set that was sourced from thousands of compromised computers. Because the data comes from stealer malware rather than a single hacked database, the credentials span a wide range of services. Banking sites, email providers, social media platforms, and corporate tools could all be represented in this file.

Plaintext passwords require no cracking. An attacker who downloads this file can begin credential stuffing attacks against live accounts immediately. The February 2026 date means the majority of these accounts are almost certainly still active, making this one of the more dangerous collections HEROIC has indexed recently.

What Was Exposed in the MetaCloudVipNew 4000 PCs.part3 Stealer Log

• Email Addresses
• Plaintext Passwords
• URLs (site-specific login context for each credential)

How This Data Enables Account Takeover, Identity Theft, and Financial Fraud

Credentials from a file like this are used in several ways. The most common is credential stuffing, where automated tools test each email and password pair against hundreds of popular services simultaneously. Even if a victim only reuses their password on two or three sites, that is enough for an attacker to gain access to email, banking, or workplace accounts. From there, the attacker can intercept password reset emails to take over additional accounts, make unauthorized purchases, transfer funds, or sell verified working credentials on dark web marketplaces.

Identity theft is also a real risk when email accounts are compromised. Attackers can use access to someone's inbox to gather personal information, impersonate them to contacts, or access linked financial and government services. The downstream harm from a single compromised account can be significant and long-lasting.

How the MetaCloudVipNew Campaign Operated

The name MetaCloudVipNew points to an organized malware distribution campaign. Threat actors running stealer campaigns typically deploy malware through fake software installers, cracked games or tools, malicious browser extensions, or phishing attacks. Once a device is infected, the stealer silently extracts all saved credentials from browsers and applications, then sends the harvested data to a remote server controlled by the attacker.

The attacker then organizes the data from thousands of infected machines into numbered parts, hence 4000 PCs.part3, and distributes these collections on Telegram where other criminals can download or purchase them. By the time a collection like this is indexed by HEROIC, it has often already been shared acros multiple threat actor communities, meaning the data may have been accessed and used by numerous individuals.
