One Telegram Channel. 17,921 Logins. The HESOYAM CLOUD Leak Landed.

17,921 Logins Exposed in the HESOYAM CLOUD Upload

HEROIC analysts found a stealer log file, labeled "HESOYAM CLOUD CloudHesoyam," uploaded to a Telegram channel on 27 Jul 2026. The file contained 17,921 records taken directly from infected devices, including email addresses, plaintext passwords, and the URLs of the accounts those logins open.

Why This Is Dangerous

This is not a database stolen from a company. It is a collection of real login sessions pulled straight from victims' own computers by malware that quietly recorded their saved passwords. Each record pairs a working password with the exact site it unlocks, meaning an attacker does not need to crack or guess anything to log in as the victim.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials were used on

Why This Matters

With 17,921 plaintext credentials in one file, this leak gives criminals a ready made list to run through banking sites, email providers, and social media platforms. Anyone who reused their password from one of these accounts elsewhere is at risk of credential stuffing, account takeover, identity theft, and financial fraud.

How Stealer Log Leaks Like This Happen

Stealer logs come from information stealing malware that infects a device through a cracked software download, a malicious attachment, or a fake update prompt. Once installed, the malware silently reads saved browser passwords, autofill data, and session details, then packages everything into a file under a name like HESOYAM CLOUD. These files are then uploaded to Telegram channels or dark web forums where anyone can download them.
