Infostealer Malware Attack Exposes Thousands of Aussie Bank Customers

Cybersecurity researchers have uncovered a disturbing new threat targeting Australians—an Infostealer malware attack that has exposed sensitive data from thousands of customers across major Australian banks. The troubling discovery reveals that the breach didn’t originate from the banks themselves but from compromised personal devices.

Here’s What They Found:

  • 14,000+ CommBank customer credentials
  • 7,000+ ANZ customer credentials
  • 5,000+ NAB customer credentials
  • 4,000+ Westpac customer credentials
  •  The Banks Weren’t Hacked — YOU Were.
    These attacks focus on infiltrating your personal computer or smartphone. The malware silently steals your login credentials, giving cybercriminals access to your accounts without you even realizing it.

Techniques Used in These Attacks:
Credential Harvesting – This method steals saved passwords from your browsers, making it easy for hackers to access your accounts.
Cookie Theft – Attackers hijack your browser’s login sessions, bypassing the need for passwords and even Multi-Factor Authentication (MFA).
Keylogging – The malware records every keystroke you make, including your passwords, sending them directly to cybercriminals.


How to Protect Yourself:
✅ Never save passwords in browsers – Use a dedicated password manager for better security.
✅ Turn on Multi-Factor Authentication (MFA) – Add an extra layer of security to your accounts.
✅ Don’t reuse the same password across sites – Use unique, strong passwords for each account.
✅ Avoid clicking suspicious or unknown links – Phishing attempts often look like legitimate emails or messages.
