Your Login May Be in the TOKYO CLOUD FREE99 Stealer Log

HEROIC's threat intelligence team found a stealer log named TOKYO CLOUD FREE99 shared on Telegram, dated July 8, 2024. The file contains 4,328 records harvested from infected devices, including email addresses, plaintext passwords, and the URLs of the sites those logins belong to.

Why the TOKYO CLOUD FREE99 Leak Is Dangerous

Stealer logs are especially risky because the credentials inside were captured directly from a victim's browser, meaning they were valid and in active use at the moment of infection. Since the passwords are in plaintext and already matched to the exact site URL they unlock, an attacker can log in immediately, no guesswork needed.

What Was Exposed in the TOKYO CLOUD FREE99 Stealer Log

• Email addresses
• Plaintext passwords
• URLs of the websites or services the credentials belong to

Why This Stealer Log Matters

Because these credentials came straight from an infected browser, they carry a higher chance of still being valid than passwords from an old breach dump. Anyone in this log faces immediate risk of account takeover, and if the affected accounts include email or shopping logins, that access can be used to reset other passwords or make fraudulent purchases.

How a Stealer Log Like This Works

A stealer log is the output of information-stealing malware that infects a device and quietly copies saved browser passwords, autofill data, and login URLs before sending everything back to whoever controls the malware. Unlike older breach dumps, stealer logs tend to contain freshly captured credentials, which is exactly what makes them valuable building blocks for combolists sold and traded on Telegram.
