Computer attacks are a growing problem all over the world and on different platforms. Now smartphones are also being attacked.
The threats of mobile ransomware are increasing and to a large extent concentrated in more developed countries as these markets represent a higher level of income and a more active and used online mobile and payment infrastructure.
The data are 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.
The rise of the US against the 2015-2016 report is mainly due to the attacks that specifically attacked America. One of them started in Germany but in the first quarter of 2017 but later focused on America with 28% of the attacks.
It is recalled that, although they do not involve mobile devices, Europe (and in part the world) has been attacked by several ransomwares, with the two biggest 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%).
