ArtHouse Cloud Logs uploaded by a Telegram User

The ArtHouse Cloud Log: 5,821 Records Leaked in an April 2025 Telegram Upload

HEROIC analysts flagged a stealer log named "ArtHouse Cloud Logs" posted to a public Telegram channel on April 1, 2025. The file contained 5,821 records pairing email addresses with plaintext passwords and the URLs those credentials unlock. Unlike a hacked database, this data was harvested directly from infected devices, meaning it reflects real, working logins at the time of collection.

Why the ArtHouse Cloud Log Is Dangerous

The passwords in this leak are plaintext, not hashed, so they can be used to log in immediately without any cracking effort. That removes the biggest obstacle attackers normally face after a breach. Anyone in this log is exposed to instant account access until they change the affected password.

What the ArtHouse Cloud Log Contained

• Email addresses tied to each affected account
• Plaintext passwords with no protection applied
• URLs showing which site or service each login belongs to

Why 5,821 Exposed Logins Is a Real-World Risk

Working credentials at this scale are commonly fed into automated credential stuffing tools that test the same email and password across hundreds of other websites. Any match leads to account takeover, and from there attackers can pivot into identity theft or financial fraud, particularly if the account is linked to payment methods or personal information.

How Stealer Logs Like This One Are Created

Information-stealing malware gets onto a device through a malicious download, pirated software, or a phishing link. Once installed, it silently harvests saved passwords, browser autofill data, and active sessions, then packages everything into a log file. Files like "ArtHouse Cloud Logs" are then uploaded to Telegram channels where they circulate freely among cybercriminals.
