Following analysis of attacks on mobile devices, cybersecurity researchers at Kaspersky have uncovered that 14.8% of its users who were targeted by malware or adware in 2019 suffered a system partition infection, making the malicious files undeletable.
Moreover, pre-installed default applications also play a role here: depending on the brand, the risk of undeletable applications varies from one to five per cent in low-cost devices and goes up to 27% in extreme cases.
A system partition infection entails a high level of risk for the users of infected devices, as a security solution cannot access the system directories meaning it cannot remove the malicious files.
According to Kaspersky researchers, this type of infection is becoming a more common way to install adware – software created to display intrusive advertising.
Infection can happen via two paths: the threat gains root access on a device and installs adware in the system partition, or the code for displaying ads gets into the firmware of the device before it even ends up in the hands of the consumer.
Among the threats uncovered in the system directories, Kaspersky found a variety of malicious programs – from Trojans that can install and run apps without the user’s knowledge to Click here to read entire article
