The LunarLogsFree Dump: 35,223 Stolen Credentials Hit the Dark Web
HEROIC analysts identified the LunarLogsFree stealer log breach, surfaced on 03 July 2025 when a Telegram user distributed a 607-file compiled log bundle through a dark web channel. The release exposed 35,223 records containing email addresses, plaintext passwords, and harvested URLs pulled from compromised endpoints worldwide. This is not a legacy breach from years past -- it is recent, active, and already circulating among criminal operaters who are using it right now.
Why This Is Dangerous
The LunarLogsFree dataset is especially hazardous because it packages three elements that together eliminate every obstacle between a criminal and their target. Email addresses identify the victim. Plaintext passwords provide instant access with zero decryption required. URLs reveal exactly which services were in use, allowing attackers to prioritize high-value targets -- banking portals, corporate VPNs, and email provders -- without any additional research. At 35,223 records, this dump represents a substantial ready-to-use attack inventory that can be cycled through credential stuffing tools in a single automated session.
What Was Exposed
- Email Addresses -- account identifiers and recovery contacts for dozens of services per victim
- Plaintext Passwords -- unencrypted credentials ready to deploy without any cracking or decryption
- URLs -- specific websites and login portals where the credentials were originally captured by the malware
Why This Matters
Stealer log breaches like LunarLogsFree are not passive data incidents -- they are active attack enablers. From the moment this data was released on Telegram, every person in the dataset became a potential target. Criminals use these records for credential stuffing, where automated bots test leaked email and password pairs against hundreds of popular websites simultaneously. Successful hits lead to account takeover, where attackers change recovery details and lock out the legimate owner. From there, the damage escalates into identity theft, unauthorized purchases, wire transfers, and downstream phishing attacks launched against the victim's contacts. The speed at which this cycle happens after a dump is released is measured in hours, not days.
How Stealer Logs Work
LunarLogsFree is a channel that aggregates and freely distributes infostealer log bundles to build credibility in criminal marketplaces. The underlying data originates from infostealer malware, which spreads through phishing emails, fake software cracks, trojanized installers, and malvertising campaigns. Once installed on a victim's machine, the malware quietly harvests saved browser credentials, session cookies, clipboard history, and in some cases cryptocurrency wallet data. The completed log is transmitted back to the attacker's infrastructure, where it is bundled with other logs and released in numbered batches. The 607-count designation means this release packaged 607 individual device logs into a single downloadable archive -- one of the larger individual drops associated with this channel. Victims typically have no idea their device was infected, or that their credentials are now freely circulating on dark web platforms.
