Developers and Remote Workers Targeted in the Lunar Cloud Logs 17,714-Record Breach

In June 2025, a stealer log file labeled LunarLogsFree 312count was uploaded to Telegram, exposing 17,714 records compiled from infected devices. The Lunar Cloud Logs dump stands out from typical credential leaks because the data includes API host URLs and endpoint references alongside email addresses and plaintext passwords. That combination points to a victim pool that includes developers, sysadmins, and remote workers who store cloud service credentails on their personal or work machines.

Why This Is Dangerous

With 17,714 records in a single upload, the Lunar Cloud Logs breach is large enough to attract serious attention from organized threat actors. The plaintext passwords eliminate any barrier to exploitation. Attackers running automated credential stuffing campaigns can cycle through this dataset against major platforms in hours. For victims whose email addresses and passwords are reused across services, a single match can cascade into a full account takeover chain spanning email, cloud storage, banking, and work tools.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (API host and endpoint references)

Why This Matters

The inclusion of API host and endpoint URLs is a significant detail. Most stealer log dumps contain only browser-saved passwords and autofill data. The presence of API credentails suggests victims may have been accessing cloud infrastructure, development environments, or remote management tools. A compromised API key or cloud login can give attackers persistent access to business systems far beyond what a stolen personal password typically provides. Small businesses and freelancers relying on cloud tools are particularly exposed.

How Stealer Log Breaches Work

Lunar Cloud Logs is a named stealer log service operating through Telegram, where malware logs are distributed freely to build reputation before being monetized. The underlying infection vector is typically info-stealing malware spread through phishing, cracked software, or malicious browser extentions. Once a device is infected, the malware silently harvests all saved credentials, session tokens, and stored URLs before sending them to the operator's collection server. The operator then bundles the results and posts them to channels like the one used for this upload.

Check If You Are Affected

HEROIC's free scanner covers more than 400 billion exposed records, including the Lunar Cloud Logs dataset. Enter your email address to check whether your credentials were part of this breach or any other known stealer log release. If your data appears, prioritize changing passwords for cloud services, work accounts, and any platform where you may have saved credentials in your browser.
