One Post. 357 Stolen Logs. MOONLOGSFREE Exposed 6,481 Records.

HEROIC analysts identified a stealer log archive posted to a public Telegram channel called MOONLOGSFREE on November 9, 2023. A single upload containing 357 log files exposed 6,481 records harvested from infected user devices. Each record included email addresses, plaintext passwords, and the specific URLs of websites and services the victims had accessed. The data was distributed freely in the channel with no restrictions, meaning any subscriber could download and use the credentials immediatly. The relatively compact size of this dataset belies its danger, as every record contains immediately actionable login information.

Why This Stealer Log Is Dangerous

What makes a stealer log like this particularly threatening is that each entry is already complete. The attacker does not need to crack anything, guess anything, or run any additional processing. The email address, the plaintext password, and the exact website where that password is used are all present together. Anyone who downloaded this archive from the MOONLOGSFREE Telegram channel recieved a ready-to-use credential kit. The 357 individual log files in this upload each represent a seperate infected device, meaning the breach affected hundreds of distinct victims across potentially hundreds of different services.

What Was Exposed

The 6,481 records contained in the MOONLOGSFREE stealer log included the following types of data:

• Email Addresses
• Plaintext Passwords
• URLs associated with specific websites and services
• API host information
• Endpoint identifiers

Why This Matters for Account Security

When plaintext passwords are paired with email addresses and specific URLs, the damage potential extends well beyond the original compromised accounts. Attackers routinely test the same email and password combination against dozens of other popular platforms in a process called credential stuffing. One exposed password can unlock banking, email, social media, and work accounts simultaneously if the victim reuses passwords across services. The API host data in this leak also suggests that developer credentials and internal service access may have been compromised alongside personal accounts, potentially widening the impact to businesses and not just individual users.

How Stealer Log Breaches Work

Each of the 357 log files in this upload represents a single compromised device. The infection process begins when a user runs a file that appears legitimate but secretly installs an infostealer, a type of malware designed to harvest credentials silently. The malware scans the device for saved browser passwords, captures login data entered into forms, records session cookies, and collects information about websites visited. It then sends all of this back to the attacker in a compact log file. Attackers gather hundreds or thousands of these files and upload them to distribution channels like MOONLOGSFREE on Telegram, where other criminals can download and use the credentials. The entire process from initial infection to public posting typically occures within a matter of days. Victims have no indication their device was compromised until accounts start showing unauthorized activity.
