Adware that can't be deleted without damaging the host system found in numerous Android Devices! / Digital Information World
It was revealed that the said infection could occur in two ways – the threat either gets root access on the target device and installs adware in the system partition, or the code responsible for showcasing ads finds its way into the device’s firmware before becoming accessible by the user. The latter could even result in the target user’s device getting its data stolen.
Triada trojans and the Lezok were discovered by Kaspersky as two of the frequent threats installed in Android smartphones’ system partition.
Shedding light on the Agent trojan for a second, it is a complicated malware that often finds shelter in the app that regulates the system’s GUI, or even in the Settings tool, in the absence of which, a smartphone fails to operate effectively. Once the threat delivers its payload, random files can be downloaded and operated on the affected device.
Sivu trojan is also known for causing considerable damage. It is packed with two modules – the first one features ads, either in notifications or on the top of other windows. As for the second module, it can install, uninstall as well as run apps.
When it comes to the Plague adware app, it is also a common type of adware that acts as if it is a genuine system service, referring to itself as Android Services. However, the truth is that it can install applications without the user’s consent and showcase ads in notifications.
Necro.d trojan, Penguin, Guerrilla, Secreted, and other malware were also found installed on various devices.
If you have a phone with already-installed adware, there’s a high probability that you can’t do much about it.
The research firm in question added that any attempt to remove pre-installed adware could impact the system. The firm also said that passionate developers who are striving to come up with an alternative firmware for devices can play a considerable role in tackling this recurring issue.
