If You Reuse Passwords, the MetaCloudVipNew 4150 PCs.part3 Leak Should Worry You

HEROIC analysts identified a stealer log file uploaded to Telegram in January 2026 under the name MetaCloudVipNew 4150 PCs.part3. The file is the third part of a collection said to represent 4,150 compromised computers, and this segment alone contained 50,716 records. Each record includes an email address, a plaintext password, and the URL of the website or service the credentials were stolen from. The scale of this file puts it well above the average stealer log and makes it a significant source for credential stuffing campaigns.

Why This Is Dangerous

Fifty thousand working login pairs, all in plaintext, is a serious resource for any attacker. These credentials do not need to be decoded or cracked. They can be loaded into an automated tool and tested against banking sites, email providers, and social platforms within hours. Because the source malware ran on real machines, many of these accounts are likely still active today. People who have not changed their passwords since early 2026 are at the highest risk.

What Was Exposed in the MetaCloudVipNew 4150 PCs.part3 Log

• Email addresses
• Plaintext passwords (unhashed and fully readable)
• URLs identifying the exact websites and services the credentials belong to

Why This Matters for Credential Reuse and Account Takeover

With over 50,000 records, the MetaCloudVipNew 4150 PCs.part3 file is the kind of dataset that fuels large-scale credential stuffing attacks. Attackers run the credentials automaticlly across popular services and collect every account that accepts the login. Email accounts are especially valueable targets because they can be used to reset passwords on other services, giving attackers cascading access. Financial fraud, identity theft, and unauthorised account activity are all probable outcomes for people whose data appears in this log.

How Information Stealer Malware Spreads Across Many Computers

The name of this file, referencing 4,150 PCs, gives some insight into the scope of the infection behind it. Information stealer malware does not target a single person. It spreads across many machines through shared download links, infected software installers, and phishing campaigns. On each infected computer, the malware silently copies browser-stored passwords, session tokens, and autofill data. Everything is then compressed and exfiltrated. The resulting archives are sorted by machine, labeled, and distributed in parts through Telegram channels and dark web marketplaces. MetaCloudVipNew 4150 PCs.part3 is one segmant of this type of bulk operation.
