HEROIC Analysts Found 649 Leaked Records in ArtHouse Cloud Logs v1

HEROIC analysts found the ArtHouse Cloud Logs v1 file circulating on Telegram in March 2026, a stealer log with 649 records pulled from infected devices. Each record includes an email address, a plaintext password, and the URL the credential was used on.

Why the ArtHouse Cloud Logs v1 Dump Is Dangerous

Even a smaller file like this one is dangerous because the data was scraped directly off an infected computer rather than guessed or cracked. The passwords are plaintext and already paired with the exact site they unlock, so an attacker can use them the moment they get the file.

What Was Exposed in ArtHouse Cloud Logs v1

• Email addresses
• Plaintext passwords
• URLs tied to each login

Why This Matters

Even 649 exposed logins are enough to fuel credential stuffing, where criminals try the same email and password combination against banking, email, and shopping accounts. Because so many people reuse passwords, anyone caught up in ArtHouse Cloud Logs v1 faces a real risk of account takeover or identity theft.

How the ArtHouse Cloud Logs v1 Stealer Log Was Built

Stealer malware typically arrives through cracked software or phishing attachments. Once it runs, it copies saved browser passwords and the websites they belong to, then reports back to the attacker. Those individual infections were combined into the 649-record file now shared on Telegram as ArtHouse Cloud Logs v1.

Check If You Are Affected

A small file size does not mean small risk if your credentials are in it. HEROIC's free breach scanner checks your email against more than 400 billion exposed records, including logs like ArtHouse Cloud Logs v1, so you can find out quickly and change anything that needs changing.
