Search Your Email: ArtHouse Cloud Logs Leaked 41,095 Accounts

HEROIC analysts identified a stealer log file named "ArtHouse Cloud Logs" uploaded to a public Telegram channel on June 15, 2025. The log contains 41,095 records tied to infected devices, largely associated with users in the United States, and exposes email addresses, plaintext passwords, and the URLs of the accounts those passwords belong to.

Why This Is Dangerous

The passwords in this log were captured and stored in plaintext, then matched directly to the exact URL where they were used. An attacker does not need to crack or guess anything. They can simply take the email and password pair and try logging in to see what account it opens.

What Was Exposed in the ArtHouse Cloud Logs Leak

• Email addresses
• Plaintext passwords
• URLs of the accounts and services those credentials unlock

Why This Matters

With 41,095 records in this log, attackers have a sizable batch of working logins to run credential stuffing attacks, testing stolen email and password pairs against banking, email, and social media sites. If any of those passwords are reused elsewhere, the risk quickly escalates into account takeover, identity theft, and financial fraud on services that had nothing to do with the original infection.

How This Stealer Log Was Built

Logs like "ArtHouse Cloud Logs" are the output of infostealer malware, which infects a device through a pirated download, cracked software, or a malicious attachment, then quietly harvests saved passwords, autofill data, and browser session details. The malware bundles everything it captures into a log file and sends it to the attacker, who then shares or sells it on Telegram channels where these dumps commonly surface.

Check If You Are Affected

Search your email now rather than wait to find out the hard way. HEROIC's free breach scanner checks your email and passwords against a database of more than 400 billion leaked records, so you can see if you were exposed in this leak or any other and know which passwords to change first.
