The KATANA_CLOUD Leak Contains Exactly 32,338 Email and Password Pairs

KATANA_CLOUD Stealer Log Exposes 32,338 Records

HEROIC analysts identified a stealer log file called KATANA_CLOUD, uploaded by a Telegram user on January 28, 2024. The file contained exactly 32,338 records, each pairing an email address with a plaintext password and the URL of the account that login belonged to. Most of the exposed accounts trace back to users in the United States.

Why the Precision of This Leak Makes It More Dangerous

This is not a vague or approximate dataset. Every one of the 32,338 records follows the same structure: an email address, a readable password, and the exact web address it unlocks. None of the passwords were hashed, so each entry is a usable login the moment the file is opened.

What the KATANA_CLOUD Leak Contains

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

Why This Matters

Because every password in this leak is stored in plain text and matched to a specific site, attackers can move directly to testing logins instead of cracking hashes. Anyone among these 32,338 people who reused a password elsewhere is at risk of credential stuffing, where the same login is tried across banking, email, and social media accounts. That risk can escalate quickly into account takeover, identity theft, or financial fraud.

How Stealer Logs Like KATANA_CLOUD Work

Stealer logs are produced by infostealer malware that infects a device and quietly copies saved browser passwords, autofill data, and session details. Once collected, that information is packaged into a log file and distributed through channels like Telegram, often within days of infection. Most victims have no idea their credentials were taken until a log like KATANA_CLOUD starts circulating.
