38,088 Plaintext Passwords From Monster Cloud Free 2 Are Now Circulating on Telegram

HEROIC analysts identified a stealer log file uploaded to a public Telegram channel on October 28, 2023. The file, circulated under the name Monster Cloud Free 2, contained 38,088 records harvested from compromised endpoint devices. Each record included an email address, a plaintext password, and one or more URLs tied to the services the victim was logged into at the time of infection. The data appears to have been collected by infostealer malware running silently on infected computers, then packaged and shared freely on Telegram for anyone to download and use.

Why This Monster Cloud Free 2 Leak Is Dangerous

Most data breaches involve hashed passwords, which at least forces attackers to crack them before doing damage. This leak skips that step entirely. Every password in this file is in plaintext, meaning anyone who downloads it can immediately try those credentials on other websites. Because people commonly reuse the same password across many accounts, a single compromised login can quickly become a domino effect touching email, banking, social media, and workplace tools. The inclusion of API host URLs makes this even more serious: attackers may be able to use stolen credentials to access backend systems and developer tools, not just consumer accounts.

What Was Exposed in This Stealer Log

• Email addresses (38,088 unique records)
• Plaintext passwords, ready to use without any cracking
• URLs and API host addresses tied to specific services
• Endpoint information identifying the compromised devices

Why This Matters for Real People

When credentials are available in plaintext, attackers don't need sophistication. They run automated tools that test your email and password combination across hundreds of websites in minutes. This is called credential stuffing, and it succeeds surprisingly often because so many people reuse passwords. If your credentials appear in this log, anyone who downloaded the file could already be inside your email, your online banking, your cloud storage, or your work accounts. Identity theft and financial fraud become realistic outcomes very quickly once this kind of access is established.

The API host data adds another layer of risk. Developers and IT professionals whose credentials were captured may have inadvertently exposed access to internal systems, cloud infrastructure, or customer databases through their compromised endpoints.

How Stealer Log Breaches Like This One Occur

A stealer log is not the result of a company's database being hacked. Instead, it comes from malware that infects individual computers. The malware, often called an infostealer or credential stealer, quietly runs in the background and copies saved passwords from your web browser, reads active login sessions, and records what you type. It then sends all of that information back to whoever is controlling it. That person can use the data themselves, sell it, or, as in this case, share it freely on platforms like Telegram to build a reputation or attract followers in cybercriminal communities. The label "free" in Monster Cloud Free 2 is literal: this data was given away at no cost, making it accessable to even low-skilled attackers.
