Inside the HESOYAM CLOUD Logs: How a Stealer Harvested 11,662 Passwords

HEROIC analysts identified the HESOYAM CLOUD CloudHesoyam dataset on February 8, 2026, after an anonymous Telegram user uploaded a stealer log file containing 11,662 compromised records. The breach exposed email addresses, plaintext passwords, and URLs harvested from infected endpoint devices across the United States. The file structure is consistent with a cloud-relay stealer operation -- a malware variant that routes exfiltrated credentials through a cloud intermediary before compiling and distributing the logs to threat actors on Telegram.

Why the HESOYAM CLOUD Leak Is Dangerous

The defining characteristic of this breach is the presence of plaintext passwords. There is no hashing, no encryption, no cracking required. Any actor who downloads this log file has immediate, ready-to-use access to 11,662 sets of credentials. Combined with the associated URLs, attackers know exactly which services each credential set belongs to, making targeted account takeover trivially easy. Victims will not recieve any breach notification from the affected services because the compromise happened at the device level, not the platform level -- the service provider itself was never breached.

What Was Exposed in the HESOYAM CLOUD Dataset

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters for Anyone Whose Device Was Infected

Stealer log victims face a different threat than typical data breach victims. Because the malware ran on their device, the attacker may have captured credentials for every website and service the victim logged into -- not just one. A single infected device can yield dozens of usable credential pairs. The HESOYAM CLOUD log also includes URLs, which map each password to its specific destination, giving attackers a ready-made targeting list. These logs are frequently resold or combined with other datasets, compounding the risk to anyone who appeared in this dump and has not yet changed their passwords or audited their accounts.

How HESOYAM CLOUD Stealer Logs Work

HESOYAM CLOUD is a cloud-assisted information stealer -- malware that installs itself on a victim's device and silently collects saved browser credentials, autofill data, and session cookies. What makes this variant distinct from simpler stealers is its use of a cloud relay to transmit harvested data, making detection harder for traditional endpoint security tools. Once the stealer runs, it packages the captured credentials into a structured log file and uploads it to a cloud staging server. The threat actor then retrieves the compiled archive and distributes it via Telegram. The February 8, 2026, upload occured without any notice to victims, making the 11,662 harvested records freely accessible to any subscriber of the channel. The entire process is seperate from the platforms whose credentials were stolen -- those services see no sign of a breach on their end.
