Your Passwords May Already Be Stolen. The MoonLogsCloud Leak Hit 12,411 Records.

In July 2025, a Telegram user uploaded a stealer log labelled MoonLogsCloud 304count that exposed 12,411 records harvested from 304 infected devices. The dataset contains plaintext passwords, email addresses, and URLs captured directly from compromised machines across the United States. HEROIC analysts confirmed the breach and added it to the database on April 18, 2026. Because the data was distributed freely on Telegram, any threat actor who downloaded it can still use those credentials today without restriction.

Why This Is Dangerous

Stealer logs are among the most actionable datasets attackers can obtain. Unlike a simple password list, these logs capture credentials in context, meaning attackers know exactly which website each password belongs to. With plaintext passwords and matching email addresses in hand, a threat actor can log directly into accounts without any cracking required. The URLs in this dataset also reveal which services each victim was actively using, letting attackers prioritize high-value targets like banking portals, email providers, and corporate logins. If the same password was used on multiple sites, the damage can spread far beyond the original infection. This is one of the most dangrous types of breach data in active circulation.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (browser-saved sites and active service endpoints)

Why This Matters

When plaintext passwords circulate freely on Telegram, they reach thousands of threat actors within hours. Credential stuffing attacks can begin immediately, attempting the same login details against dozens of platforms. Because many people reuse passwords, a single stealer log exposure can cascade into account takeovers on banking platforms, social media, and workplace systems. Identity theft and financial fraud are direct downstream risks. The MoonLogsCloud data has been publicly available since July 2025, which means attackers have had months of unrestricted access. Victims typically recieve no formal notification, leaving them exposed without any warning at all.

How Stealer Logs Work

A stealer log is created when infostealer malware runs silently on a victim's device. The malware scans saved browser passwords, cookies, and browsing history, then transmits everything to the attacker's server in seconds. The attacker bundles the harvested records into log files organized by device count, such as 304count indicating 304 infected machines, and distributes them through Telegram channels or dark web forums, often at no cost. The malware is usually delivered through phishing emails, fake software downloads, or compromised installers. Victims almost never know their device was infected until they discover their accounts have been acessed by someone else.

Check If You Are Affected

HEROIC's free breach scanner searches across more than 400 billion exposed records, including the MoonLogsCloud 304count stealer log, to tell you immediately whether your email address or passwords appear in this breach or any other. Do not wait for a notification that may never come. Run your free HEROIC scan now, change any compromised passwords, enable two-factor authentication, and monitor your accounts for unauthorized activity before further damage is done.
