MARVEL_PRIME 02.12 2: 8,535 Records Exposed in a Single Telegram Post

On December 16, 2022, HEROIC analysts spotted a stealer log labeled "MARVEL_PRIME 02.12 2" uploaded to a public Telegram channel. One post, one file, 8,535 records pulled from infected devices. The exposed data included email addresses, plaintext passwords, and the URLs of the sites those credentials unlocked, a complete, ready to use set of logins for anyone who downloaded the file.

Why This Is Dangerous

Plaintext passwords are the most dangerous kind of leaked credential because there is nothing standing between the attacker and the account. There is no hash to crack, no encryption to break. An attacker only needs to match an email address with its password and the site it belongs to, then log in directly. That is what makes a small, focused stealer log like this one just as risky as a much larger breach.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Every one of the 8,535 exposed records represents a working login somewhere on the internet. If any of those people reused the same password for email, banking, or social media, an attacker now has a path into those accounts too. This is exactly how credential stuffing attacks work: automated tools take leaked email and password pairs and test them against dozens of other websites until one succeeds, leading to account takeover, identity theft, or financial fraud.

How Stealer Logs Work

A stealer log is generated by information stealing malware, malicious software that infects a device and quietly scans browsers and saved data for anything resembling a login credential. Once collected, the stolen usernames, passwords, and URLs are bundled into a file, in this case one labeled "MARVEL_PRIME 02.12 2," and shared through channels like Telegram, either sold or given away for free. Because the malware captures credentials the moment they are typed, even a strong, unique password will not protect an account if the device itself is infected.
