Researchers Track HESOYAM CLOUD Leak: 7,637 Records Found

Researchers Track a 7,637-Record HESOYAM CLOUD Leak

HEROIC analysts tracked a stealer log file named HESOYAM CLOUD CloudHesoyam to a Telegram channel, where it was uploaded on 26 July 2026. Researchers confirmed the file held 7,637 records pulled from infected devices, including email addresses, plaintext passwords, and the URLs those credentials were used on.

Why This HESOYAM CLOUD Leak Is Dangerous

What researchers flagged first was the plaintext passwords: none of the credentials in this file are encrypted or hashed, so they can be read and used exactly as they were typed by their original owners. Combined with the exact login URL attached to each record, this gives anyone who downloads the file a direct path to try signing in to real accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials were captured from

Why This Matters

Analysts note that files like this are commonly used for credential stuffing, where an attacker tests each stolen email and password against other popular websites. If your login is among the 7,637 records here, and you have reused that password elsewhere, a single successful match can lead to account takeover on more than one service.

How Stealer Logs Work

According to HEROIC's research, stealer logs are generated by malware that infects a device, often through pirated software or a disguised download, and then quietly pulls saved browser passwords and autofill data. That stolen information is packaged into a file, and files like HESOYAM CLOUD are typically shared or sold on Telegram, giving buyers access to credentials gathered from many different infections.

Check If You Are Affected

Researchers recommend checking your exposure directly rather than waiting to see if your accounts are affected. HEROIC's free breach scanner compares your email against more than 400 billion leaked records, so you can find out quickly whether you were part of this leak and secure any exposed passwords.
