ArtHouse Cloud Logs v2 Leak Could Unlock Email and Bank Accounts

HEROIC found the ArtHouse Cloud Logs v2 stealer log on April 18, 2026, exposing 80,872 records containing email addresses, plaintext passwords, and URLs.

Why the ArtHouse Cloud Logs v2 Breach Is Dangerous

ArtHouse Cloud Logs v2 is a large-scale stealer log that handed attackers 80,872 email-and-password pairs targeting United States users. All passwords are in plaintext, making this dataset immediately actionable for credential stuffing against major platforms. The login URLs included with each record identify which services each victim was using, allowing attackers to prioritize high-value targets like online banking, email providers, and corporate software platforms.

What Was Exposed in the ArtHouse Cloud Logs v2 Leak

• Email Addresses -- 80,872 U.S. user accounts at immediate risk
• Plaintext Passwords -- working credentials requiring no decryption
• URLs -- login endpoints identifying which services each victim was accessing

Why This ArtHouse Cloud Logs v2 Data Puts You at Risk

An email address exposed in a stealer log functions as a pass key to every account that uses it for password recovery. With 80,872 records in circulation, automated tools can test these credentials against banks, e-commerce sites, and corporate systems within hours of the log being distributed. One successful match gives attackers inbox access, which they then use to intercept two-factor authentication codes and trigger password resets on financial accounts, often draining them before victims realize anything is wrong.

How Stealer Logs Work

Stealer malware infects devices through phishing emails, fake software, and malicious ads. Once active, it silently captures browser-saved passwords and session tokens before transmitting them to remote servers. The harvested data is cleaned, sorted, and packaged into logs like ArtHouse Cloud Logs v2, then distributed via Telegram channels where cybercriminals purchase or download them for large-scale credential stuffing campaigns.
