One Combo File. Part 15 of Many. ArtHouse Has 3.4M Stolen Credentials.

On June 28, 2026, a Telegram user uploaded the ArtHouse COMBO URL_part_0015, the 15th file in a large multi-part credential dump. This single installment contains 3,473,588 records and exposes email addresses, plaintext passwords, and site URLs. The existence of at least 15 separate files suggests the full ArtHouse COMBO dataset could be suprisingly larger, potentially containing tens of millions of records across all parts combined.

Why the ArtHouse COMBO Breach Is Dangerous

Multi-part combo lists like ArtHouse COMBO are among the most dangerous types of credential exposures. The 3.4 million records in part 15 alone represent three million individuals whose email and plaintext password are now in criminal hands. The URL field in each record directs attackers to a specific site, eliminating any guesswork about where to attempt a login. Even one file from a multi-part dump is enough to compromise millions of accounts.

What Was Exposed in the ArtHouse COMBO Leak

• Email Addresses
• Plaintext Passwords
• URLs

Why This ArtHouse COMBO Data Puts You at Risk

If your credentials appear in part 15, they are likley present in other parts of the ArtHouse COMBO dump as well, depending on how many services you have saved passwords for. Each exposed record gives an attacker an exact starting point: your email, your password, and the website to target. From there, the same password is actualy tested against banking, email providers, and anywhere else criminals think you might have reused it.

How Stealer Logs Work

Stealer malware infects devices and extracts all saved browser passwords into a structured log file. When operators compile these logs, they often split them into multiple parts for easier distribution. Each part, like ArtHouse COMBO URL_part_0015, represents one chunk of a larger stolen credential archive. Criminals who download even one part gain access to millions of valid login records without needing to compromise any system themselves.
