Small But Real: KATANA_CLOUD PRIVATE 3569 Exposed 88 Passwords

Alongside the smaller file in this series, HEROIC analysts also tracked KATANA_CLOUD PRIVATE 3569, posted to the same Telegram channel on 27-Aug-2026. It lists 88 records pairing email addresses with plaintext passwords and the exact URLs they unlock. Every entry is stored as readable text, so the file is immediately usable, which is reason enough to check your own email against it.

Why 88 Working Logins Is Not Nothing

Eighty eight records will not make headlines next to breaches involving millions, but each line is still a full set of working credentials. An attacker can work through a list this size quickly, trying every email and password pair against the listed site and anywhere else it might also work.

The Login Data Exposed in KATANA_CLOUD PRIVATE 3569

• Email Addresses
• Plaintext Password
• URLs

How a Small List Still Creates Real Risk

The danger here is the same as in any credential leak, just on a smaller scale: reused passwords. If any of these 88 logins match a password used on a different account, that account is now exposed too, regardless of how small the original file was.

Where Files This Size Come From

Smaller logs like this one typically trace back to a handful of infected devices rather than a large scale operation. Info-stealer malware on those devices pulls saved browser credentials and autofill details, then bundles whatever it collects into a file ready for distribution. The resulting file is no different in format from larger dumps, just shorter, which means it slots just as easily into an attacker's existing tools.

Check Whether You Are Part of This File

Scan your email to see if your details appear in this leak or elsewhere in HEROIC's breach database. A match means it is time to change that password, and to do the same anywhere else you reused it, whether for personal use or work.
