How ArtHouse Cloud Logs v1 Leaked Emails and Passwords via Telegram

HEROIC analysts traced a stealer log dated 30 Jul 2026 called ArtHouse Cloud Logs v1 back to a Telegram channel, where it was uploaded by an individual user. The file contains 4,550 records, each combining an email address, a plaintext password, and the URL of the site the credentials were stolen from.

Why the ArtHouse Cloud Logs v1 Leak Is Dangerous

This file gives an attacker everything needed to log in without any extra work. The passwords are stored in plaintext, so there is nothing to crack, and each one is already matched to an email address and the exact URL of the site it opens.

What Was Exposed in ArtHouse Cloud Logs v1

• Email addresses
• Plaintext passwords
• URLs of the sites each login is tied to

Why This Leak Matters Beyond the Original Malware Infection

The device that leaked these 4,550 credentials may have nothing to do with you directly, but the passwords collected from it might match ones you use elsewhere. That overlap is exactly what credential stuffing exploits, feeding stolen logins into other services until one works, leading to account takeover, identity theft, or fraudulent purchases far from where the original infection happened.

How ArtHouse Cloud Logs v1 Likely Ended Up on Telegram

This is a textbook stealer log path: malware infects a device, quietly copies saved browser credentials and the URLs tied to them, and reports everything back to the person running the malware. That person then names, versions, and uploads the resulting file, in this case labeled "v1", to a Telegram channel where it circulates among other buyers and sellers of stolen data.
