14k Japan Stealer Log Leaks 13,473 Emails and Passwords

14k Japan Stealer Log Exposes 13,473 Email and Password Pairs

HEROIC analysts found a stealer log titled "14k Japan" on Telegram in July 2026, containing 13,473 records made up of email addresses, plaintext passwords, and the login URLs tied to each account.

Why This Is Dangerous

These passwords were stored in plaintext, so anyone with the file can log in directly without needing to crack anything. With over 13,000 pairs in one log, an attacker has plenty of accounts to try, and reused passwords let a single leak spread damage across multiple unrelated services.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs (the exact pages the credentials unlock)

Why This Matters

A log of this size is large enough to fuel automated credential stuffing against banking, email, and shopping sites. Anyone who reused one of these passwords elsewhere faces a real risk of account takeover, and the exposed email addresses alone make convincing phishing attempts easier to pull off.

How This Kind of Stealer Log Is Made

Infostealer malware infects a device through a phishing link, fake download, or cracked software installer, then quietly exports every saved username, password, and site from the browser. That data is compiled into a text log and uploaded to Telegram, where files like "14k Japan" get named for their approximate record count and shared or sold to other criminals.

Check If You Are Affected

Do not assume your credentials are safe just because this particular log has an unfamiliar name. HEROIC's free breach scanner checks your email against more than 400 billion breached and leaked records, so you can confirm your exposure and reset any at-risk passwords right away.
