US Accounts Exposed as ArtHouse Cloud Logs Leaks 36,529 Records

ArtHouse Cloud Logs: 36,529 US Accounts Exposed on Telegram

On June 17, 2025, HEROIC analysts identified a stealer log labeled "ArtHouse Cloud Logs" uploaded to a public Telegram channel. The file contained 36,529 records harvested from infected devices, including email addresses, plaintext passwords, and the URLs of the sites those credentials unlocked. The records are tied to accounts in the United States, meaning a large pool of American users has real, working credentials sitting in a file anyone on that channel could download.

Why This Is Dangerous

Because the passwords in this log are stored in plaintext and paired with the exact web address each one unlocks, an attacker does not need to crack or guess anything. They can simply match an email address to its password and the site it belongs to, then log in directly as the account owner. With 36,529 records in one file, the scale of potential account takeover is significant.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Every one of the 36,529 exposed records represents a working login somewhere on the internet. If any of those people reused their password for email, banking, or social media, an attacker now has a path into those accounts too. This is exactly how credential stuffing attacks succeed: automated tools take leaked email and password pairs and test them against dozens of other websites until one works, leading to account takeover, identity theft, or financial fraud.

How Stealer Logs Work

A stealer log is the output of information stealing malware, malicious software that quietly infects a device and scans browsers, saved logins, and autofill data for anything resembling a credential. Once collected, the stolen data is bundled into a file, in this case one labeled "ArtHouse Cloud Logs," and shared through channels like Telegram, sometimes sold and sometimes given away for free. Because the malware captures credentials the moment they are typed, even a strong, unique password will not protect an account if the device itself is infected.
