The KATANA_CLOUD Leak: 22,443 Passwords Exposed. Yours Might Be One.

HEROIC analysts found a stealer log named KATANA_CLOUD FREE uploaded to a Telegram channel on April 26, 2024. The file exposed 22,443 records, plain and simple: an email address, a plaintext password, and a URL for each one. No cracking is needed to use any of it.

Why This Is Dangerous

Every password in this file is stored in plaintext, which means whoever has it can read your login directly and try it against the exact site listed. There is no delay, no decryption step, no barrier at all between having the file and having your account.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

Leaks like KATANA_CLOUD FREE are used for credential stuffing, where attackers take stolen email and password pairs and try them across banks, email providers, and shopping sites in bulk. With 22,443 records in this file, that is 22,443 chances for someone to reuse a password and open themselves up to account takeover, identity theft, or financial fraud.

How Stealer Logs Work

A stealer log comes from infostealer malware that infects a device through a fake download, cracked software, or a phishing link. Once running, it copies saved passwords, autofill data, and browsing details straight from the device and bundles them into a file. That file, named KATANA_CLOUD FREE, was then uploaded to a Telegram channel, putting 22,443 sets of stolen credentials into the hands of anyone who wanted them.
