Android Malware — It’s Spreading Rapidly
It May Be a Good Time to Stop Using Android
The recent rapid spread of ransomware shows no sign of slowing down, with the volume of mobile ransomware increasing by 350 percent in the first quarter of this year. The Kaspersky study found that ransomware targeting all devices, systems, and networks continue to grow, with 11 new cryptor families and 55,679 new modifications making their appearance in the first quarter.
In the first quarter, Kaspersky registered a growth in attacks involving mobile ransomware from the Trojan-Ransom.AndroidOS.Egat family: the number of users attacked by this type of malware increased more than 13 times from the previous quarter.
In the first quarter, Kaspersky noted that the Trojan-Banker.AndroidOS.Asacub mobile banker was actively spreading. Over three months, the representatives of this family attacked more than 43,000 mobile devices, which was 2.5 times more than in the previous quarter. After clicking a malicious link, users were directed to a page where they were prompted to view an MMS that concealed the Trojan, which was then downloaded to the device.
In the quarter,14 Trojans that use advertising as their principal means of monetization (highlighted in blue in the table) made it into the TOP 20. Their goal is to deliver as many adverts as possible to the user, employing various methods, including the installation of new adware. These Trojans may use superuser privileges to conceal themselves in the system application folder, from which it will be tough to delete them.
