The NCSC is alerting around 26,000 people across New Zealand that their devices have been infected with a stealthy form of malware — putting personal, banking, and government-system credentials at risk. RNZ
What is Happening?
The malware, known as Lumma Stealer, is designed to quietly infiltrate computers (mainly running Microsoft Windows), harvesting sensitive data such as email addresses, login credentials, passwords — and potentially more. RNZ
Some of the compromised credentials reportedly belonged to users of government-agency systems and banking platforms — raising serious concerns that go beyond isolated cases. RNZ
Why This Is a Big Concern
According to the NCSC’s Chief Operating Officer Michael Jagusch, it’s the first time the agency has had to contact such a large group directly about malware infections. RNZ
He explained that while malicious software has long been a threat, what’s particularly alarming is the scale — and the fact that malware like this is increasingly easy to acquire on the darknet. RNZ
Because of the widespread use of digital tools in everyday life — online banking, government services, email, shopping — many more Kiwis are exposed to potential vulnerabilities than ever before. RNZ+1
How Infection Likely Happened
NCSC believes that most of those affected did not get targeted personally. Rather, they likely became victims by:
- Clicking a malicious link in a phishing email, or
- Downloading software from compromised or fraudulent websites. RNZ
Once installed, the malware remains hidden and quietly gathers data that attackers can exploit for financial theft or further phishing attacks. RNZ
The Bigger Picture — Cybercrime as an Industry
Jagusch pointed out that malware like Lumma Stealer is now part of a broader, commercialised cyber-crime ecosystem. For a comparatively small cost, almost anyone — regardless of technical skill — can acquire tools that were once only used by advanced hackers. RNZ
This democratization of cyber-threats dramatically increases the risk for everyday device users and small businesses, meaning no one can afford complacency. RNZ+1
What to Do If You’re Concerned
If you received one of the NCSC’s warning emails or suspect your device might be compromised:
- Visit the official NCSC guidance page (e.g., “Own Your Online”) for detailed instructions. RNZ
- Run a full scan with a reputable anti-virus or anti-malware tool to detect and remove threats.
- Change all passwords — especially for banking, email, and sensitive accounts — and enable multi-factor authentication wherever available.
- Be vigilant about email links, downloads, and avoid unverified software or sites.
