With ArtHouse Cloud Logs New, Attackers Can Log Into Your Accounts Today

HEROIC analysts identified a stealer log collection labeled ArtHouse Cloud Logs New that appeared on Telegram on March 12, 2026. The file contained 1,650 records, each pairing an email address with a plaintext password and the URL of a targeted service or API endpoint. This release came just days after the ArtHouse Cloud Logs v1 and v2 files surfaced on the same platform, making it the third named release tied to ArtHouse Cloud infrastructure tracked by HEROIC in a single week. The label "New" suggests this was intentionally positioned as a fresh batch, separate from and likely supplementing the earlier collections.

What Attackers Can Do With Credentials From ArtHouse Cloud Logs New

Plaintext passwords from the ArtHouse Cloud Logs New file hand attackers a direct path into real accounts. There is no guessing, no cracking, no technical skill required. The first thing a criminal does with a list like this is run it through automated credential stuffing tools, software that tries each email and password combination against popular services like Gmail, Outlook, PayPal, Amazon, and banking portals. If a victim reuses the same password across services, those accounts fall in minutes. The URLs included in this file make the attacks even sharper, because attackers already know which platforms the victims actively use. That information enables precisley targeted phishing messages designed to look like legitimate alerts from familiar services, making victims far more likely to hand over additional credentials or personal information.

What Was Exposed in ArtHouse Cloud Logs New

• Email Addresses: Active login identifiers linked to real user accounts across multiple platforms
• Plaintext Passwords: Fully readable, immediately usable passwords with no technical barrier to exploitation
• URLs: Specific service addresses and API endpoints showing which systems were accessed by the infostealer malware

Why Three ArtHouse Cloud Releases in One Week Signals Ongoing Exposure

When HEROIC tracks three stealer log releases from the same source within days of each other, it points to a sustained operation rather than a single incident. Taken together, the three ArtHouse Cloud log files from March 2026 account for more than 11,000 exposed records. For anyone whose credentials appear across multiple releases, the risk compounds. Their email and password may already be circulating through several criminal channels simultaneously, being tested against account after account in credential stuffing runs. Identity theft, unauthorized financal transactions, and account takeover become realistic outcomes, not abstract possibilitys.

How Infostealer Malware Creates Files Like ArtHouse Cloud Logs New

The ArtHouse Cloud Logs New file was not taken from a corporate database. It was built record by record from individual devices infected with infostealer malware. That malware typically arrives through a phishing link, a malicious attachment, or a trojanized software installer. Once active on a device, it works quietly, reading saved browser passwords, capturing login sessions, and noting which URLs the user visits. It then sends all of that data back to the operator, who packages it into a named collection and uploads it to Telegram. The whole process happens without the victim knowing. No warning, no error message, no sign that anything is wrong.
