US Stealer Log Leak Exposes 35,850 ArtHouse Cloud Login Records

On 10-Jun-2026, a Telegram user quietly posted a stealer log dump known as ArtHouse Cloud Logs New v2, and it didn't take long for researchers to notice. The file contained 35,850 individual records, each one a small window into someone's online life: an email address, a plaintext password, and the URL of the site it unlocked. This wasn't a sophisticated corporate hack. It was the output of malware that had been sitting quietly on infected machines, receiving every keystroke and saved credential before shipping it off to whoever controls the botnet.

Why This Is Dangerous

Stealer logs like this one are especially nasty because they arrive ready to use. There's no cracking or guessing involved since the passwords are stored in plaintext, sitting right next to the email address and website they belong to. Anyone who downloads this file from Telegram can start testing logins imediately, and because so many people reuse the same password across multiple accounts, a single stolen credential often opens several doors at once: email, banking, social media, and work systems included.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs
• 35,850 total records affected

Why This Matters

It's easy to assume a leak tied to the United States and a random Telegram upload isn't a big deal, but that assumption is exactly what attackers count on. These logs get traded, resold, and combined with other leaked datasets to build detailed profiles of victims. Even if you don't recognize the source name ArtHouse Cloud Logs, if your credentials ended up in this batch, your accounts are seperate targets for anyone who bought or downloaded this file.

How Stealer Logs Work

A stealer log is generated by infostealer malware, a type of program designed to sit silently on a victim's device and harvest anything valuable: saved browser passwords, autofill data, cookies, and even cryptocurrency wallet files. Once the malware collects this information, it packages everything into a log file and sends it back to the attacker. From there, logs are often shared or sold in bulk on Telegram channels and dark web forums, exactly the kind of channel where ArtHouse Cloud Logs New v2 surfaced. The victim usually has no idea any of this occured until their accounts start behaving strangely.
