How the Moon Logs MOONLOGSFREE 2 Campaign Led to 3,047 Stolen Logins

In August 2023, a stealer log file known as Moon logs - MOONLOGSFREE 2 250pcs was uploaded to a Telegram channel and began circulating among threat actors. HEROIC analysts identified and catalogued the file, which contained 3,047 records. Each record paired an email address with a plaintext password and the URL of the service where those credentials were originally harvested from an infected device. The breach was added to HEROIC's database on May 14, 2026.

How the Moon Logs MOONLOGSFREE Malware Campaign Led to 3,047 Stolen Logins

The Moon logs - MOONLOGSFREE 2 250pcs file did not come from a hacked database. It came from real people's computers. Infostealer malware was installed on a collection of devices, quietly harvesting browser-saved credentials in the background. Once the malware had gathered enough data, it packaged the results into a structured log file and transmitted it back to the operator.

That operator then organised the logs into batches and distributed them through Telegram under the MOONLOGSFREE channel name, making them freely available to anyone with access to the channel. The 250pcs notation in the file name refers to the number of individual log bundles in this particular release. The total record count across those bundles came to 3,047 compromised accounts.

What Was Exposed in the Moon Logs MOONLOGSFREE 2 File

• Email Addresses: Real email addresses connected to active user accounts
• Plaintext Passwords: Unencrypted passwords that attackers can use immediately without any cracking
• URLs: The exact web services where credentials were stolen from infected machines

Why This Matters: Free Stealer Logs Are the Most Dangerous Kind

Paid credential logs circulate in limited markets. Free logs like the MOONLOGSFREE releases reach a far wider audience. When a threat actor distributes stolen credentials at no cost on Telegram, the file is downloaded by hundreds of people in a short period. Each download is a potential credential stuffing attempt against every platform those email and password pairs touch.

The 3,047 accounts in this file are at risk of unauthorised access, identity theft, and financial fraud. If the same password was used on banking apps, email accounts, or subscription services, all of those are exposed. The URL data makes it even worse: attackers allready know exactly which services to target for each victim, eliminating the guesswork entirely.

How MOONLOGSFREE Stealer Logs Are Made and Distributed

Infostealer malware is typically spread through malicious email attachments, fake software cracks, or trojanised browser extensions. Once installed on a victim's machine, it runs silently and harvests credentials from the browser's saved password store, active session cookies, and any autofill data it can access. The associated URLs are captured alongside the credentials, giving attackers a complete picture of the victim's online activity.

The harvested data is then packaged into log files and sent to a centralised collection point. Operators like the one behind MOONLOGSFREE sort these logs into batches and release them in numbered series, often through public or semi-public Telegram channels. This makes the data availible to a broad range of threat actors, not just sophisticated buyers. The Moon logs - MOONLOGSFREE 2 250pcs file is one release in that series, catalogued by HEROIC after it appeared on Telegram in 2023.
