You might be reading this because you searched your own email address, and if so, here's the number you need to know: 167,328. That's how many accounts turned up in ArtHouse CLoud Logs v5, uploaded April 27, 2026, the fifth and largest entry in a series that started with just 1,796 records.

Why This Is Dangerous

If you're one of the 167,328 people in this file, your email and plaintext password are currently sitting in a Telegram channel accessible to anyone who wants them. You don't get a say in who sees it, and you likely have no idea it happened unless you go looking, which is exactly why you should.

What Was Exposed

  • 167,328 email addresses paired with plaintext passwords
  • URLs tied to each credential, showing precisely where it applies
  • The largest confirmed release across all five versions of this series

Why This Matters

If your password shows up here, you're not just at risk on whatever site the URL points to, you're at risk anywhere you reused that same password, wich for most people is definately more places than they'd like to admit. This file alone eclipses the combined total of the first four versions put together.

How You End Up in a File Like This

You don't need to click anything obviously suspicious to end up here. A cracked program, a fake browser extension, or a malicious ad can quietly install an infostealer that scoops up your saved logins without you ever noticing a slowdown or a warning sign. By the time a file like v5 gets uploaded, the damage to your accounts has allready happened.

Check If You Are Affected

You don't have to guess whether you're one of the 167,328. HEROIC's free scanner checks your email against more than 400 billion breached records, covering this entire ArtHouse Cloud Logs series, so you can find out right now and start changing passwords before someone else uses them.
