HESOYAM CLOUD Stealer Log: 37,103 Records, Plaintext Passwords, Confirmed Leaked

HEROIC analysts identified a stealer log breach attributed to HESOYAM CLOUD CloudHesoyam uploaded by a Telegram User, surfacing on February 1, 2026. The breach contains 37,103 records pulled from infected machines, including email addresses, plaintext passwords, and the URLs tied to each credential pair. The logs were shared through Telegram channels frequented by cybercriminals seeking ready-to-use account data.

Why This Is Dangerous

With 37,103 records in a single upload, this breach represents a significant volume of immediately usable credentials. Every record includes not just a username and password but the exact website where that combination was entered, making it straightforward for attackers to attempt targeted logins without any guesswork. The plaintext format means there is no cracking step required, which lowers the barrier for even low-skill threat actors to cause real harm.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (websites where credentials were used)

Why This Matters

Data from stealer logs feeds directly into credential stuffing campaigns, where automated bots systematically test stolen logins across hundreds of services. Even one successfull account takeover can cascade into identity theft, fraudulent purchases, or unauthorized wire transfers. If the compromised email is also your account recovery address for other services, attackers can chain breaches together and lock you out of your entire digital life. Financial fraud and personal data theft are the most common end results.

How Stealer Logs Work

Stealer logs originate from infostealer malware installed on victim computers without their knowlege. The infection typically arrives via a phishing email, a cracked software download, or a fake update prompt. Once active, the malware scans the browser for saved credentials, copies session tokens, and records keystrokes. All of that data is compressed into a log and exfiltrated to a remote server. Cybercriminals then sell or trade these logs on dark web markets and messaging platforms like Telegram, where they reach a broad audience of potential attackers.
