One Telegram Upload. 12,844 Records. The ArtHouse Logs Leak Is Real.

HEROIC analysts identified a stealer log file, uploaded to a public Telegram channel on April 12, 2025, under the name ArtHouse Logs For Checker. The file contains 12,844 records, including email addresses, plaintext passwords, and URLs pointing to the services those credentials unlock.

Why the ArtHouse Logs For Checker Leak Is Dangerous

Every password in this dataset was stored in plaintext, so anyone who downloads the file can log in immediately with no cracking involved. The included URLs show exactly which sites or services each credential pair opens, making it simple for an attacker to jump straight from the file to an active account takeover.

What Was Exposed in the ArtHouse Logs For Checker Leak

• Email addresses
• Plaintext passwords
• URLs (linked login endpoints)

Why This Matters

Credentials harvested this way are working logins at the moment of theft, not guesses. If you reused any of these passwords elsewhere, attackers can run credential stuffing against your other accounts, leading to account takeover, financial fraud, or identity theft. The paired email addresses also make targeted phishing far more convincing.

How Stealer Log Leaks Like This Happen

Infostealer malware infects a device, then silently collects saved browser passwords, autofill data, and the URLs tied to each login before sending it all back to whoever controls the malware. Rather than being sold quietly, logs like this one are often dumped or shared for free on Telegram, which is exactly how this 12,844-record file became public.

Check If You Are Affected

If you want to know whether your email or passwords appear in this leak or any other, HEROIC's free breach scanner checks your details against a database of more than 400 billion exposed records. Run a scan and update any password you have reused on other accounts.
