TOKYO CLOUD FREE7 Stealer Log Breach: How 4,081 Records Leaked

HEROIC discovered 4,081 records exposed in the TOKYO CLOUD FREE7 stealer log breach on February 9, 2023. The file is the seventh entry in an early Japan-themed free-tier series posted to Telegram and contained email addresses, plaintext passwords, and API host URLs captured from infected endpoints.

Why This Stealer Log Is Dangerous

TOKYO CLOUD FREE7 is dangerous because it was published openly as a free sample, meaning the barrier to entry for abuse is essentially zero. Its early position in the FREE series suggests the operator was seeding a pipeline, so victims face reuse across later mixed batches and resold packs for months afterward.

What Was Exposed in TOKYO CLOUD FREE7

• Login credentials (usernames, passwords)
• Browser cookies and session tokens
• Autofill form data
• Crypto wallet data (where present)
• System fingerprints

Plaintext passwords plus API host URLs mean attackers can pivot from user accounts to backend services in minutes.

Why This Matters

API host URLs inside stealer logs are a force multiplier, letting attackers probe cloud consoles and internal dashboards rather than only consumer logins. Combined with password reuse, a free sample like TOKYO CLOUD FREE7 can become the foothold that enables business email compromise or full cloud account takeover.

How a Stealer log Like TOKYO CLOUD FREE7 Works

An infostealer first infects a machine through a pirated installer or malicious ad, then harvests credentials, cookies, autofill data, and crypto wallets from local browsers. The operator bundles the output into a log file, names it as part of a free-tier series, and drops it on Telegram to attract buyers for the paid mixes.
