Inside MolverCloud: How Stealer Malware Harvested 3,222 Passwords

Inside the MolverCloud Stealer Log

HEROIC analysts found a stealer log file, cataloged as "MolverCloud" and dated December 14, 2022, uploaded to a public Telegram channel. The file contains 3,222 records tied to users in the United States, each pairing an email address with a plaintext password and the URL of the site or API endpoint it unlocks.

Why This Is Dangerous

Because the passwords in this file were captured in plaintext, an attacker does not need to crack or guess anything before using them. Every record already links a working password to the exact site it opens, which means the step between finding this file and breaking into an account is nearly instant.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites and services tied to each login

Why This Matters

Even at 3,222 records, this file is enough to fuel credential stuffing attacks against banking, email, and shopping accounts. Anyone whose password shows up here faces a real risk of account takeover, and if that password was reused elsewhere, the risk extends to identity theft and financial fraud on unrelated accounts.

How a Stealer Log Like MolverCloud Gets Made

Stealer logs come from malware that infects a device, often through a pirated download, fake installer, or malicious attachment. Once running, it quietly copies saved browser passwords, autofill data, and visited URLs, then bundles everything into a log file sent back to whoever controls the infection. Those logs are then traded, sold, or given away on Telegram channels, exactly where HEROIC found this one.
