Your Login May Be Exposed: KATANA_CLOUD FREE Leaked 13,825 Records

KATANA_CLOUD FREE Stealer Log Exposes 13,825 Records

HEROIC analysts found a stealer log file labeled "KATANA_CLOUD FREE" uploaded by a Telegram user on November 24, 2024. The file exposed 13,825 records containing email addresses, plaintext passwords, and the URLs each credential belongs to. As with other stealer logs, this data appears to have been pulled directly from infected devices rather than stolen from a company database.

Why This Is Dangerous

Plaintext passwords mean there is nothing standing between the attacker and your account. There is no hash to crack or encryption to break. Anyone who gets hold of this file can pair the email address, password, and site URL together and log in immediately, without needing any technical skill.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Lists like this one fuel credential stuffing attacks, where automated tools try each stolen email and password combination across other popular sites. If you reused this password anywhere else, that account is at risk too. The outcome can range from account takeover to identity theft or direct financial fraud, especially when the leaked URLs point attackers straight to the right login page.

How Stealer Logs Work

Stealer logs come from infostealer malware that infects a device through a malicious download, cracked software, or a phishing link. Once running, it quietly collects saved browser passwords, autofill details, and session data, then bundles everything into a log file. These files are commonly shared or sold on Telegram channels shortly after collection, which is exactly how this dataset became public.
