Your Passwords May Be Exposed. The Wako_Cloud Log Leaked 11,153 Logins.

Your login credentials may already be sitting in a criminal's hands. HEROIC analysts identified a stealer log tied to a service called Wako_Cloud, uploaded to a Telegram channel through the LOGSYNC group on May 27, 2025. The file contains 11,153 records made up of email addresses, plaintext passwords, and the URLs those credentials were used to log into.

Why This Is Dangerous

Because the passwords in this log are stored in plaintext and matched directly to a URL, an attacker does not need to crack or guess anything. They can open the file and start logging into accounts immediately, on the exact sites the malware recorded.

What Was Exposed in the Wako_Cloud Stealer Log

• Email addresses tied to infected devices
• Plaintext passwords, stored with no encryption
• URLs identifying which sites and services each login belongs to

Why This Matters

With 11,153 records exposed, this log gives attackers a sizable, ready-made list for credential stuffing across email providers, banks, and cloud services. Anyone whose credentials appear here faces a real risk of account takeover, identity theft, or financial fraud, often with no idea their device was ever infected.

How Stealer Logs Work

A stealer log is generated by malware that infects a device, often through a fake download, cracked software, or a malicious attachment. Once installed, it quietly pulls saved logins and browsing data straight out of the browser and sends everything back to the attacker. That data is packaged into a file, like this Wako_Cloud dump, and shared or sold through Telegram channels such as LOGSYNC. Because the malware captures whatever is saved on the device at once, a single infection can expose logins to many unrelated accounts.

Check If You Are Affected

If you use cloud storage services and are concerned your device may be infected with stealer malware, HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records. It takes seconds to find out if you are exposed and which passwords to change right away.
