18,077 Accounts Exposed in the HESOYAM CLOUD Stealer Log

HEROIC found: On August 12, 2025, a Telegram user uploaded a stealer log through HESOYAM CLOUD, exposing 18,077 records containing email addresses, plaintext passwords, and URLs from compromised endpoints and services.

Why the HESOYAM CLOUD Breach Is Dangerous

The HESOYAM CLOUD stealer log exposed over 18,000 accounts in a single upload, representing a large volume of immediately actionable credentials. Because the passwords are in plaintext and tied to specific API host URLs, attackers have a precise, ready-to-use attack package requiring zero preparation before launching account takeover attempts.

What Was Exposed in the HESOYAM CLOUD Leak

• Email addresses
• Plaintext passwords
• URLs associated with compromised accounts and services

Why This HESOYAM CLOUD Data Puts You at Risk

With 18,077 exposed accounts, the HESOYAM CLOUD breach creates significant risk for credential stuffing attacks across popular platforms. Attackers prioritize accounts with email access, financial services, and cloud storage, using automated tools to test each credential against dozens of sites within hours of obtaining the data.

How Stealer Logs Work

Infostealer malware spreads through phishing attacks, malicious software installers, and browser exploit kits. After compromising a device, it harvests every saved password and active session token it can find. Criminals then sort this stolen data into organized log files and share them via Telegram channels for other attackers to exploit.
