HEROIC Analysts Link TOKYO CLOUD FREE124 to 6,262 Stolen Logins

HEROIC analysts identified a stealer log uploaded to a Telegram channel on August 16, 2024, tied to a source labeled TOKYO CLOUD FREE124. The file contained 6,262 records, each pairing an email address with a plaintext password and the URL of the account it belonged to.

Why HEROIC Flags the TOKYO CLOUD FREE124 Data as High Risk

Analysts pay close attention to logs like this because nothing is protected. There is no hashing, no encryption, just an email, a password, and the exact site it opens, sitting in plain text for anyone who downloads the file to read and use immediately.

What HEROIC Found Inside the TOKYO CLOUD FREE124 Log

• Email addresses tied to real accounts
• Plaintext passwords with no encryption
• URLs showing which login pages the credentials unlock

Why This Matters: 6,262 Logins Now in Circulation

Once a log like this reaches a public channel, it spreads quickly to anyone running credential stuffing campaigns. Attackers test these email and password pairs against banks, email providers, and shopping sites, banking on the fact that many people reuse the same password across multiple accounts. That is how one leaked stealer log can lead to identity theft and financial fraud far beyond its original source.

How Analysts Believe This Stealer Log Was Built

Logs like TOKYO CLOUD FREE124 typically originate from infostealer malware that infects a device through a fake download, cracked software, or malicious attachment. Once running, it copies saved browser passwords and autofill data, then compiles everything into a log file, which is then uploaded and shared, in this case on a public Telegram channel.
