Cyber attacks, specifically ransomware, are a growing problem on different platforms around the world and smartphones are no exception.
The threats of mobile ransomware are increasing, especially in developed countries, as these markets represent a higher level of income and a more active and used online mobile and payment infrastructure.
The data is from Kaspersky Lab’s annual ransomware report for 2016-2017, which explains that this type of attack is more attractive to criminals because of the ease of transfer of the ransom.
The document highlights that in the first quarter of 2017 mobile ransomware activity reached 218,625 trojan installation packages, a number that is 3.5 times higher than the previous quarter. This activity soon decreases to the average values observed in previous years, which is a concern to be taken into account.
The total number of users who encountered ransomware between April 2016 and March 2017 increased by 11.4% compared to the previous 12 months (April 2015 to March 2016) – from 2,315,931 to 2,581,026 users across the country world.
The US moved from fourth to first, with regard to the percentage of attacks by ransomware, with almost 19% of the attacks. Canada and Germany were soon followed by almost 19 percent and more than 15 percent, respectively.
It is recalled that, although it did not involve mobile devices, Europe (and in part the world) has been attacked by several ransomwares, with the two largest cases of recent months being WannaCry and ExPetr.
The 10 countries with the highest number of users attacked with ransomware on the PC, in proportion to all users attacked with any type of malware in 2016-2017 are: Turkey (almost 8%), Vietnam (about 7.5%), India (more than 7%), Italy (about 6,6%), Bangladesh (more than 6%), Japan (almost 6%), Iran (almost 6%), Spain (almost 6%), Algeria 4%), and China (almost 3.8%).
