HEROIC Analysts Found NETHERLANDS COMBO in Private Telegram Channels

HEROIC analysts identified this stealer log on 25-Aug-2025. The breach exposed 190,455 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as NETHERLANDS COMBO uploaded by a Telegram User.

Why This Is Dangerous

This breach contains email addresses and plaintext passwords targeting Netherlands-based accounts. Plaintext passwords require no cracking before use, so attackers can begin attempting logins immediately. The included URLs reveal which websites the victims used, giving attackers a ready-made list of accounts to target with credential stuffing attacks.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

With email and password pairs in hand, criminals can attempt to access email accounts, online banking portals, government services, and social media platforms. For Netherlands residents, this is especially concerning given the widespread use of single email logins across banking and government systems. Victims face risks of identity theft, financial fraud, and account takeover.

How Stealer Logs Work

Stealer logs are files produced by infostealer malware that gets installed on a victim's computer without their knowledge. The malware is typically delivered through phishing emails, malicious software downloads, or booby-trapped websites. It records saved passwords, login credentials, and browsing activity, then sends the collected data to criminals who package and distribute it through private Telegram channels and dark web forums.
