Inside hotmail.fi: How Malware Harvested 7,018 Login Credentials

HEROIC analysts identified this stealer log on 02-Jun-2026. The breach exposed 7,018 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as hotmail.fi uploaded by a Telegram User.

Why This Is Dangerous

This breach contains 7,018 hotmail.fi email addresses and their plaintext passwords, harvested directly by malware running on infected devices. With no decryption required, attackers can immediately access these email accounts and any other service where the same passwords are used.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (website addresses linked to the stolen login credentials)

Why This Matters

Email account access gives attackers far more than just inbox access. A compromised email can be used to reset passwords on linked accounts, intercept two-factor authentication codes, and impersonate the account owner. With 7,018 accounts exposed, the scale of potential identity theft and account takeover is significant.

How Stealer Logs Work

Stealer malware installs itself on a device through phishing emails, malicious downloads, or fake software tools. Once active, it silently monitors everything the user types, capturing email addresses and passwords as they log in. The collected data is then sent to the attacker and distributed in dark web communities and private Telegram channels where others can purchase and exploit the credentials.
