Dark Web Intel: 12,479 Credentials in the ArtHouse Cloud Logs

12,479 Stolen Credentials Surface in the ArtHouse Cloud Logs

HEROIC analysts tracked a stealer log dump, dated 31-Jul-2026, that a Telegram user uploaded under the name ArtHouse Cloud Logs v3. The file holds 12,479 records combining email addresses, plaintext passwords, and the URLs or endpoints those credentials belong to, all pulled from infected devices by information-stealing malware.

Why Stealer Log Data Is Especially Dangerous

Unlike a leak from a single company's database, a stealer log captures whatever was sitting in a victim's browser at the moment their device got infected. That means the passwords are current, active, and paired with the exact site each one unlocks. Because the passwords are stored in plaintext, anyone who gets this file can log straight into an account without cracking anything first, using the exact URL listed alongside each credential.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs and endpoints

Why This Matters

Because stealer logs contain live, working credentials, they are a direct path to account takeover the moment they circulate. Attackers buy and trade logs like this one specifically because the login pairs still work, and they use them for credential stuffing against other sites, identity theft, and financial fraud when banking or payment portals are among the exposed URLs.

How Stealer Logs Like This Get Made

A stealer log is the output of information-stealing malware that infects a device, usually through a malicious download, cracked software, or phishing link, and then quietly copies saved browser passwords, autofill data, and session cookies before sending them back to whoever controls the malware. The stolen data is bundled into a log file and sold or shared, often through Telegram channels like the one this file surfaced on, sometimes within days of the original infection.

Check If You Are Affected

HEROIC's database tracks more than 400 billion breached records, including stealer logs like this one that circulate quietly before wider discovery. Run a free scan to see if your email address or passwords appear in this log or any other breach on file.
