Your Login May Be Exposed. ‘HarmonyCloud 470’ Leaked 6,679 Logins.

HEROIC analysts identified a stealer log labeled "HarmonyCloud 470" uploaded to a Telegram channel on May 27, 2024. The file contains 6,679 records pulled from infected computers, including login endpoints, email addresses, API hosts, and plaintext passwords harvested directly from victims' devices.

Why Older Stealer Logs Still Pose a Risk

Although this log surfaced back in 2024, that does not mean the accounts inside it are safe. Many people never change a password unless prompted, so credentials from this file can still work years later. Because the passwords are plaintext, anyone who has this log can try each one directly with no cracking required.

What Was Exposed in the HarmonyCloud 470 Log

• Email addresses
• Plaintext passwords
• Login endpoint URLs

Why This Matters Even Years Later

If your email and password are among these 6,679 records and you have not changed that password since 2024, an attacker can still use it today for credential stuffing across banking, email, and shopping sites, opening the door to account takeover, identity theft, or financial fraud.

How the HarmonyCloud 470 Stealer Log Was Made

Stealer logs are created by infostealer malware that infects a computer, often through a fake download or malicious attachment, and then silently copies saved passwords, cookies, and login details from the browser. The results are packaged into a log file and later shared or resold, in this case surfacing again on Telegram under the name "HarmonyCloud 470."

Check If Your Login Is Still in This Stealer Log

Even older stealer logs are worth checking against, since reused passwords rarely expire on their own. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, so you can find out and change any exposed passwords that are still active.
