Inside HolyCloud Private 148: 1,196,265 Passwords Harvested

In June 2026, HEROIC detected the 148th installment in the HolyCloud Private stealer log series on Telegram. This release contains 1,196,265 credential records—email addresses, plaintext passwords, and the corresponding URLs of websites where each credential was entered. The data was systematically extracted from compromised endpoints by infostealer malware operating across thousands of infected machines.

1.19 Million Passwords With Zero Encryption

The technical reality of this leak is stark: every password in the HolyCloud Private 148 file exists in unencrypted plaintext. There is no bcrypt, no SHA-256, no salting—just raw strings that match what each victim typed into their login forms. From a technical standpoint, exploiting these credentials requires nothing more than a web browser and the ability to copy and paste.

What Was Exposed

• Email Addresses – 1.19 million account identifiers mapped to real individuals and their online services
• Plaintext Passwords – Raw, unprocessed password strings extracted directly from browser credential databases
• URLs – Full endpoint URLs revealing the exact login pages and web applications targeted

Automated Credential Stuffing at Industrial Scale

A dataset of 1.19 million credential pairs fuels large-scale credential stuffing operations. Attackers deploy tools like OpenBullet or SentryMBA to test these pairs against API endpoints and login forms at rates of thousands per minute. Even with a success rate below 1%, a dump this large yields thousands of compromised accounts across email services, financial platforms, cloud storage providers, and enterprise applications.

Dissecting the HolyCloud Infostealer Pipeline

The HolyCloud operation represents an industrialized stealer log supply chain. At the front end, infostealer malware—predominantly Lumma, RedLine, and Vidar variants—infects endpoints through drive-by downloads, SEO-poisoned search results, and malvertising campaigns. The malware hooks into browser processes to extract credentials from Chromium and Firefox password stores, decrypting them using the victim's OS-level encryption keys. Captured data is structured into standardized log formats (URL:login:password) and uploaded to the HolyCloud Telegram channel, where new volumes appear regularly.

Check If Your Credentials Were Exposed

The sheer scale of 1,196,265 records means statistically significant numbers of users are affected. HEROIC's breach intelligence platform indexes more than 400 billion compromised records across all known breaches and stealer log collections. Run your email through the HEROIC breach scanner to check whether your credentials appear in HolyCloud Private 148 or any other indexed data exposure.
