How the ArtHouse CLoud Logs v2 Stealer Log Exposed 13,916 Logins

What HEROIC Analysts Found in the ArtHouse CLoud Logs v2 Dump In July 2026, HEROIC analysts identified a stealer log file titled "ArtHouse CLoud Logs v2" uploaded to Telegram on July 30, 2026. The file contained 13,916 records, each pairing an email address with a plaintext password and the URL of the site or service where that login was captured. This is a sizable stealer log, meaning nearly 14,000 people had their login activity silently recorded by malware running on their own device. Why the ArtHouse CLoud Logs v2 Dump Is Dangerous Unlike a leak from a hacked company database, a stealer log comes directly from infected computers. That means the passwords in this file are current, since they were captured at the moment someone actually typed them in. The paired URLs tell an attacker exactly which website or app each password unlocks, turning this into a ready-made list of working logins rather than a puzzle that needs to be solved. What Was Exposed in the ArtHouse CLoud Logs v2 File Email addresses Plaintext passwords URLs identifying which account each password belongs to Why This Matters for the 13,916 People in This Log Because stealer logs capture real, active credentials, they are especially valuable to attackers running credential stuffing and account takeover campaigns. If someone in this dump used the same password across multiple sites, an attacker now has a direct path into their email, banking, or social media accounts. From there, the risk quickly extends to financial fraud and identity theft, since a compromised email account is often the key that unlocks password resets everywhere else. How a Stealer Log Like ArtHouse CLoud Logs v2 Gets Created Stealer logs come from malware, often called an info-stealer, that infects a device through a malicious download, cracked software, or phishing link. Once installed, the malware quietly reads saved passwords, browser autofill data, and login sessions, then sends everything back to the attacker in bulk. Files like this one are frequently repackaged and uploaded to Telegram channels or dark web forums, where they are sold or shared with other criminals looking for working credentials.
