High-tech economies face uphill struggle with malware
[]
As the hackers behind last week’s global ransomware cyber attack make a new demand for payment, experts warn other emerging threats could be even worse. 
Without re-building entirely segregated systems, cyber security consultant Rudiger Herda says everything from cash machines to petrol stations will remain one giant, openable door for malware.
WannaCry exploits vulnerabilities in a Microsoft system that’s more than a decade old. Even in super-modern European economies like Germany’s, companies aren't well protected.
Sandro Gaycken, a director from NATO SPS Cyberdefense, said: “A lot of people don’t really know what IT security is, how to do it properly, which products to buy, the whole IT security market is pretty amateur as well. So it’s very hard to make a good choice, and this is certainly a bigger problem for the German economy on the ground level.” 
The so-called Wanna‍Cry malware continues to spread, particularly in Asia, and has already affected 150 countries.
