HolyCloud Private 139 Stealer Log Leaks 1.2M Credentials: How It Works

HolyCloud Private 139: How a 1.2 Million Record Stealer Log Works

On June 7, 2026, HEROIC analysts identified a stealer log file labeled "HolyCloud Private 139," uploaded by a user on a Telegram channel. Marked as a "private" release, the file contained 1,195,867 records, each pairing an email address with a plaintext password and the URL the login was used on.

Why This Is Dangerous

Being labeled "private" typically means this log was intended for a smaller, invite-only group of criminals before it eventually spreads more widely, which can give attackers a head start before broader detection. With nearly 1.2 million plaintext credentials in one file, whoever holds it can test logins across a huge number of accounts immediately, with no cracking required.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each login

Why This Matters

At nearly 1.2 million records, this leak provides attackers with enough volume to run large-scale credential stuffing campaigns against banks, email providers, and retailers. Because the passwords are stored in plaintext and many people reuse them across accounts, a single leaked credential here can cascade into email takeover, financial fraud, or identity theft well beyond the original exposed service.

How Stealer Logs Work

A stealer log like "HolyCloud Private 139" is built from infostealer malware that infects victims' devices, often through pirated software, fake installers, or malicious email attachments. The malware silently harvests every saved username and password from the browser and sends it to the attacker. Criminals then compile the results from many infections into large combined files, sometimes labeling select batches "private" before eventually selling or leaking them more broadly on Telegram and dark web forums.

Check If You Are Affected

Given the size of this leak, checking your exposure is a worthwhile step no matter which sites you use. HEROIC's free breach scanner searches more than 400 billion leaked records, including large private stealer logs like this one, to show you if your email address has been compromised. Run a free scan today and change any password that comes back as exposed.
