ArtHouse Premium Stealer Log Exposes 66K US Credentials

In November 2025, a stealer log file was uploaded to Telegram exposing 66,522 records tied to ArtHouse Premium users in the United States. The data set -- known as ArtHouse Premium Cloud Logs.part2 -- contains plaintext passwords alongside email addresses and URLs, making it one of the more damaging credential dumps to surface that month. If you have an account anywhere that shares a password with your ArtHouse Premium login, that account is now at risk.

Stealer logs are collected by malware quietly installed on victims' computers. Unlike database hacks where a company gets breached, stealer logs harvest credentials directly from your browser or device, which means no amount of corporate security can protect you from them. The plaintext passwords in this set means attackers have everything they need to log in right now, no cracking required.

Records Exposed in the ArtHouse Premium Cloud Logs.part2 Data Set

The 66,522 records in this breach included several types of sensitive user information:

• Email Addresses -- used to identify accounts and target phishing campaigns
• Plaintext Passwords -- fully readable, no decryption neccesary for attackers
• URLs -- reveals which sites the victims were logged into, helping attackers prioritize targets

The combination of email plus plaintext password plus the URL where that password was used is essentially a complete account takeover package. Attackers don't need to guess anything -- they know exactly where you logged in and what you typed.

ArtHouse Premium Cloud Logs.part2 and the Broader Credential Abuse Problem

Once a stealer log like this one gets uploaded to Telegram, it spreads fast. Threat actors download it, run automated tools against every URL in the file, and start testing credentials within hours. This process -- known as credential stuffing -- works by taking the exact username and password combos from the breach and trying them on other sites like Gmail, Amazon, or your bank.

Account takeover from stolen credentials is one of the most common ways people lose access to their email, financial accounts, and social media profiles. The ArtHouse Premium data set is a real-world example of how malware on one device can cascade into multiple account compromises across dozens of services. Victims often don't realize anything happend until they're locked out.

Breaking Down Stealer Logs: What It Means for Victims

A stealer log breach is different from a typical database leak. Here's what sets it apart:

• Device-level compromise: The malware ran on the victim's own computer or phone, harvesting credentials as they were typed or stored in the browser.
• No hashing, no salt: Passwords in stealer logs are captured before any encryption happens, so they're always stored in plaintext form.
• Broad scope: One infected device can expose logins to dozens of sites, not just ArtHouse Premium.
• Hard to detect: Many victims never recieve any notification because no single company was breached -- the data was pulled from their device.

If your device was infected at any point before November 2025, your credentials may be circulating in sets like this one right now.
