According to the study, smartphones account for 72% of all mobile Internet infections. It also shows that the Android device infection rate reached 69% in 2017. NOKIA said that in the field of smart phones, the vast majority of malware is currently distributed as Trojan applications. Users are phishing, advertising, or other social engineering scams, downloading and installing apps.
The main reason why Android platforms are targeted is that, once the side load is enabled, the Android application can be downloaded from anywhere. The platform also recorded a 0.94% infection rate per month. NOKIA says that, despite Google's efforts to prevent malware from entering mobile phones, malware can be installed through text messages and e-mail. The presence of third party stores also plays an important role. These third party stores in China are more popular than the official app stores.
The NOKIA report shows that Windows devices cover a small fraction, only 28% of malware infections are observed. NOKIA acknowledged that the Windows device infection rate eventually turned to smart phones, because it is now becoming the preferred method of access to the internet. In addition, the report also shows that iOS and other devices cover 3.54% of the infection rate.
The intelligence report also referred to the WannaCry fiasco. According to the company's findings, WannaCry ransomware caused the largest extortion attack in history, infecting more than 230 thousand computers in 150 countries. NOKIA said that if security personnel found a completely closed WannaCry effect DNS address, WannaCry ransomware damage may be much greater. This DNS address effectively shut down malware and prevent the spread of malware.
