privatArtHouse Cloud Logs Breach: 55,291 US Records Exposed

HEROIC analysts identified a large stealer log named privatArtHouse Cloud Logs.part01, uploaded to a Telegram channel by an anonymous user in January 2026. The file contained 55,291 records, each pairing an email address with a plaintext password and the exact URL the credential was used on.

A Closer Look at Where the Data Points

Records in this log are tagged to the United States, meaning a large share of the exposed logins trace back to American users. Stealer logs like this one often circulate widely once posted, but the concentration of United States based accounts makes this particular file especially relevant for anyone in the country who reuses passwords across multiple sites.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the exact login pages tied to each account)

Why This Matters

With over 55,000 plaintext credentials in a single file, this is the kind of dataset attackers love. Because the passwords are not encrypted or hashed, they can be used immediately in credential stuffing attempts against banking, email, and shopping sites. Anyone who reused a password across accounts faces a real risk of account takeover, identity theft, and financial fraud stemming from this single leak.

How Stealer Logs Like This Get Collected

Infostealer malware spreads through fake downloads, cracked software, or malicious links, then quietly embeds itself on a victim's device. From there it scans the browser for saved passwords, autofill data, and active session tokens, pulling everything into one organized file. Large logs such as this one are often assembled from many infected machines over time before being packaged and uploaded to Telegram or dark web marketplaces, where they are sold or given away in bulk.

Check If You Are Affected

With over 55,000 records in play, the odds that your information appears somewhere in a log like this are higher than you might think. HEROIC's free breach scanner searches more than 400 billion leaked records, including stealer logs pulled directly from Telegram, so you can check your exposure in seconds and take action right away.
