Dark Web Intel: 53,017 Credentials From the ArtHouse Cloud Logs Dump

HEROIC analysts detected a stealer log file distributed on a public Telegram channel on November 2, 2025, labeled ArtHouse Cloud Logs. The upload was discovered through dark web and Telegram threat intelligence monitoring that HEROIC runs continuously across illicit credential-sharing communities. The dump contained 53,017 records and was immediately flagged for verification due to its size and the inclusion of plaintext passwords. After analysis, our team confirmed the dataset as authentic, containing live email addresses, unencrypted passwords, and service URLs collected from compromised endpoints.

Why This Is Dangerous

A dump of this size circulating on Telegram is immediately accessible to thousands of threat actors simultaneously. Anyone who downloaded the ArtHouse Cloud Logs file has 53,017 ready-to-use credential pairs requiring zero additional work to exploit. The plaintext passwords mean attackers can begin automated login attempts across email providers, banking apps, and SaaS platforms within minutes of obtaining the file. The included URLs identify which services victims were actively using, giving attackers a prioritized target list for account takeover attempts.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• Service and API Host URLs

Why This Matters

Fifty-three thousand exposed accounts represents a meaningful attack surface. When credentials like these are posted to Telegram, they are typically consumed by credential stuffing bots within hours. These bots test each email and password pair against dozens of platforms, looking for valid logins. Successful matches lead to account takeovers, which are then monetized through identity theft, unauthorised financial transactions, resale of access, or use as launchpads for broader corporate intrusions. Victims are often unaware their accounts have been compromised until significant damage has already occurred.

How Telegram Stealer Log Distribution Works

Telegram has become a primary distribution channel for stolen credential logs because it offers near-anonymous file sharing at scale with minimal moderation. Threat actors upload stealer logs directly to channels or bots, where subscribers download them for free or for small payments in cryptocurrency. The logs themselves originate from infostealer malware infections on victim devices, where credentials are scraped from browsers, applications, and system storage. Once a log is posted to Telegram, it is effectively public. It gets downloaded, repackaged, and redistributed across additional channels and dark web forums within hours. The ArtHouse Cloud Logs designation suggests these credentials were harvested from users of cloud-related platforms and services before being bundled and shared.

Check If You Are Affected

If you use any cloud storage, hosting, or creative platform services and have not recently changed your passwords, your credentials may be included in this dump. HEROIC's breach intelligence database contains over 400 billion compromised records and is updated continuosly with new verified breaches.
