Researchers Found CloudHesoyam Stealer Log With 9,577 Logins

Breach monitoring turned up a new file on 24 May 2026 called HESOYAM CLOUD CloudHesoyam, sitting quietly in a Telegram channel with 9,577 stolen login records tucked inside, not something the average person would ever imediately notice.

Why This Is Dangerous

Discoveries like this one matter because most people never find out their credentials were exposed until something goes wrong. CloudHesoyam sat available for download the moment it was posted, meaning anyone tracking that channel had access well before wider attention arrived.

What Was Exposed

• Email addresses tied to each of the 9,577 records
• Plaintext passwords with no encryption in place
• URLs documenting where each login was originally used

Why This Matters

Finding a leak like this occassionally happens through routine scanning of known breach channels, not because the attackers announce what they've done. That gap between when a file appears and when it gets noticed is exactly when the most damage can happen.

How Stealer Logs Work

CloudHesoyam came together the same way most stealer logs do: malware infected a group of devices, silently read every password the browser had saved, and exported that data to an attacker who compiled it into one file for release.

Check If You Are Affected

You don't need to wait for a researcher to stumble across your information the way this file was discovered. HEROIC's free scanner checks your email directly against more than 400 billion leaked records, so you can find out immediately and act before someone else does.
