TOKYO CLOUD PRIVTAE100 Breach: Who Was Targeted? 11,192 Records

HEROIC analysts uncovered a stealer log named TOKYO CLOUD PRIVTAE100, posted to a Telegram channel by an anonymous user in November 2023. The file held 11,192 records, each pairing an email address with a plaintext password and the exact web address the login belonged to.

Who This Breach Targets

Stealer logs like this one do not target a single company. They target ordinary people who happened to have infected devices, capturing whatever accounts they had logged into at the time, banking portals, email inboxes, streaming services, work tools, and more. Anyone whose credentials were auto filled or typed on a compromised machine during that window could be swept into this file, regardless of where they live or what they do for work.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the exact login pages tied to each credential)

Why This Matters

Because these credentials are stored in plaintext and already linked to specific websites, criminals can move straight to credential stuffing attacks, trying the same email and password combination across banking, shopping, and social accounts. If a password was reused anywhere else, that account is now at risk too. This is how a single leaked log file can snowball into full account takeover, identity theft, and financial fraud for the people caught up in it.

How This Stealer Log Was Built

Infostealer malware infects a device through a fake download, cracked software, or a malicious attachment. Once it is running, the malware quitely searches the browser for saved passwords, autofill entries, and active session cookies, then bundles everything it finds into a log file. That log, like TOKYO CLOUD PRIVTAE100, is uploaded to a Telegram channel or dark web marketplace where other criminals can browse, download, and use it. Because the credentials were captured live from a working session, they tend to be more reliable than data pulled from an old corporate breach.
