Number of mobile malware attacks doubles in 2018
DURBAN – Four African countries made the list in terms of top 10 countries by share of users attacked by mobile malware; Nigeria climbs from fifth place in 2017 to third in 2018.
Kaspersky Lab researchers have seen the number of attacks using malicious mobile software nearly double in just a year. In 2018 there were 116.5 million attacks, compared to 66.4 million in 2017, with a significant increase in unique users being affected.
Despite more devices being attacked, the number of malware files has decreased, leading researchers to conclude that the quality of mobile malware has become more impactful and precise. These and other findings are unveiled in Kaspersky Lab's report Mobile malware evolution 2018.
As the world becomes more mobile, the role of smartphones in business processes and day to day life is growing rapidly. In response, cybercriminals are paying more attention to how they are distributing malware and the attack vectors used. The channels through which malware is delivered to users and infects their devices is a key part of the success of a malicious campaign today, taking advantage of those users who do not have any security solutions installed on their phones.
The success of the distribution strategies is demonstrated not only by the increase in attacks but also the number of unique users that have encountered malware. In 2018 this figure rose by 774,000 on the previous year, to 9,895,774 affected users.
Among the threats encountered, the most significant growth was in the use of Trojan-Droppers, whose share almost doubled from 8.63 percent to 17.21 percent. This type of malware is designed to bypass system protection and deliver there all sorts of malware, from banking Trojans to ransomware.
“In 2018, mobile device users faced what could have been the fiercest cybercriminal onslaught ever seen. Over the course of the year, we observed both new mobile device infection techniques, such as DNS hijacking, along with an increased focus on enhanced distribution schemes, like SMS spam.
This trend demonstrates the growing need for mobile security solutions to be installed on smartphones – to protect users from device infection attempts, regardless of the source,” said Viсtor Chebyshev, a security expert at Kaspersky Lab.
Four African countries made the list in terms of top 10 countries by share of users attacked by mobile malware – Nigeria in 3rd place at 37.72 percent, Algeria in 5th place (35.06 percent), Tanzania in 8th place (31.34 percent) and Kenya in 9th place with 29.72 percent.
In order to protect your devices, Kaspersky Lab security experts advise the following:
- 1. Only install mobile applications from official app stores, such as Google Play on Android devices or the App Store on iOS
- 2. Block the installation of programmes from unknown sources in your smartphone’s settings
- 3. Do not bypass device restrictions as this might provide cybercriminals with limitless capabilities to carry out their attacks
- 4. Install system and application updates as soon as they are available — they patch vulnerabilities and keep devices protected.
Note that the mobile OS system updates should never be downloaded from external resources (unless you are participating in official beta-testing). Application updates can only be installed through official app stores
