The Hunter_Cloud Stealer Logs Gave Hackers 43,123 Working Logins

In August 2026, HEROIC's threat intelligence analysts identified a stealer log file uploaded to Telegram by an anonymous user, tracked as "HUNTER_CLOUD PRIVATE LOGS PART 1 uploaded by a Telegram User." The file contains 43,123 records covering endpoints, email addresses, API hosts, and plaintext passwords, along with the login URLs tied to each set of credentials.

Why This Is Dangerous

Unlike a list compiled from an old breach, a stealer log is pulled directly from infected devices, meaning the credentials inside are usually current and actively in use. This particular log gave hackers 43,123 sets of email addresses, plaintext passwords, and the exact URLs those logins open, along with API host and endpoint details that can help an attacker map out which services and systems a victim actually uses.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each credential pair

Why This Matters

Because stealer log data tends to be fresh, credentials pulled from it are more likely to still be active than those in an older leak. If your information is among these 43,123 records, an attacker could log directly into your accounts without needing to guess a current password. Reused passwords make the risk worse, letting one infected device turn into account takeover, financial fraud, or identity theft across multiple services.

How Stealer Logs Work

Stealer logs come from malware that infects a device, often through a fake download or malicious attachment, and then quietly harvests passwords, cookies, and autofill data saved in the browser. Everything the malware collects, including which websites and API endpoints the device connected to, gets bundled into a log file and sent back to the attacker, who then sells or shares it, in this case on Telegram in parts, like this "Part 1" file.

Check If You Are Affected

If any of your devices could be infected with credential-stealing malware, checking your exposure matters now, not later. HEROIC's free breach scanner searches more than 400 billion exposed records, including this leak, so you can see if your credentials are part of it and change your passwords before an attacker uses them.
