36,680 Login URLs and Passwords Leaked in ArtHouse Cloud Logs

Every entry in the file follows the same three-part pattern: an email address, a plaintext password, and the exact web address where that password was typed in. HEROIC analysts identified this pattern across all 36,680 records inside a stealer log dataset called ArtHouse Cloud Logs New, uploaded to a Telegram channel in January 2026. It is a small detail, but it is what turns a pile of stolen data into a ready-made attack kit.

Why This ArtHouse Cloud Logs Leak Is Dangerous

Because each record links a password directly to the site it belongs to, there is no guesswork for whoever downloads the file. An attacker does not need to figure out where a stolen password might work. The log already tells them, down to the exact login page.

That specificity is what seperates a stealer log from a random password dump. It turns a bulk file of stolen data into thousands of ready-to-use keys, each one labeled with the exact door it opens.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

Plaintext passwords mean an attacker can use the credentials the moment they open the file, no cracking required. If any of the 36,680 people affected reused a password across other accounts, criminals can attempt the same login on banking, email, or shopping sites in a process known as credential stuffing.

From there the risk escalates quickly. A single successful login can lead to full account takeover, drained accounts, and identity theft, especially when the compromised account is an email inbox that can be used to reset passwords everywhere else.

How Stealer Logs Work

Stealer malware infects a device through cracked software downloads, malicious ads, or fake browser updates. Once installed, it quietly pulls saved passwords, autofill entries, and session cookies straight out of the victim's web browser.

The stolen data is then compiled into a structured log file and distributed through dark web forums and Telegram channels, exactly where this ArtHouse Cloud Logs dataset appeared. Buyers use the logs to hunt for anything valuable, from banking logins to corporate accounts.

Check If You Are Affected

You cannot manually check every account you own against every leak that surfaces online. HEROIC's free breach scanner searches a database of over 400 billion leaked records, including stealer logs like this one, so you can quickly see if your email address turns up and change any passwords that need it.
