ArtHouse Cloud Logs v1 Leak: 10,743 Records, More Than a Small Town Holds

HEROIC analysts identified a stealer log dataset, tracked as ArtHouse Cloud Logs v1, that a Telegram user uploaded to a public channel on 16-Jul-2026. The file contains 10,743 records harvested from infected devices, including email addresses, plaintext passwords, and the URLs of the login pages those credentials belong to.

Why This Is Dangerous

This is a small file compared to some of the mass breaches HEROIC tracks, but the risk to each person in it is just as high. Every record pairs a working email address and password with the exact site the login unlocks, so anyone who grabs this file can log straight into an account without any extra effort.

What Was Exposed

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

Why This Matters

A leak of 10,743 records may sound small next to the billion-record breaches that make headlines, but small stealer logs like this one circulate quietly and often go unnoticed by the people affected. If a password in this file is reused anywhere else, attackers can use it for credential stuffing, taking over accounts, and in some cases pivoting into identity theft or financial fraud.

How Stealer Logs Work

Stealer log malware infects a device, usually through a fake download, pirated software, or a malicious attachment, then silently copies saved browser passwords, autofill details, and session data. It bundles everything into a single log file that gets sold or shared, often through Telegram channels like the one where this file surfaced. Because the malware grabs whatever is saved in the browser, a single infected device can expose credentials for many unrelated accounts at once.
