There was an explosion in new strains of malware in the first six months of 2015, according to security researchers at G DATA.
They recorded a 64.8 percent increase in new malware strains for the first half of 2015 compared to the first six months of 2014. It works out to an average of 12 new strains being created every minute.
With the US, China and France being hosts to the most malicious and fraudulent websites, the total number of malware strains this year is expected to be far in excess of the 2014 total.
Researchers point to Wells Fargo as the financial services company most often targeted by banking trojans, with the Swatbanker family being the most frequently seen banking trojan during the six-month period. The upward trend is a important because it indicates the first significant growth in trojan attacks since 2012.
“About three-quarters of internet users are conducting their financial transactions online, and cyber-criminals have recognised this huge opportunity for malicious attacks,” said Andy Hayter, security evangelist for G DATA.
For the first time, websites in the healthcare industry were most often classified as malicious (26.6 percent), with technology and telecom trailing at 11.6 percent.
The most common malware campaign was “Money Rain". Thirty percent of the websites connected to Money Rain were in the healthcare industry but it was also discovered in all categories researched.
The “Top 10” list of prevented malware attacks was topped by adware and Potentially Unwanted Programmes (PUPs).
G DATA noted that exploits for vulnerabilities are now being merged into exploit kits within a matter of days, underscoring the importance of keeping apps, software and patches up to date.
