Security researchers discovered 42 models of low-cost Android smartphones infected with dangerous Triada banking trojan.
Researchers from Dr.Web, a Russia based Antivirus firm discovered it and said that all the 42 models sold were already infected the Android.Triada.231 banking trojan.
“In the middle of 2017, Doctor Web analysts discovered a new Trojan Android.Triada.231 in the firmware of some cheap models of Android devices. Since this detection, the list of infected devices has been constantly increasing. At the moment, the list contains over 40 models. Doctor Web specialists have monitored the Trojan’s activity and now we can publish the results of this investigation.”
The Triada trojan was first spotted in 2016 which aims at stealing financial and personal data from the devices.
The trojan can root devices and infect the process of a core android system component zygote which is used to launch all applications. The only way to remove the malware is by wiping out the entire device and reinstalling the OS.
Once the trojan is injected into this module, they can penetrate other running applications. By this way, they can carry out malicious activities without user intervention.
This is not the first time pre-installed malware are discovered on Android devices earlier in July 2017 Dr.Web researchers discovered the same Triada trojan in four Android models which are Leagoo M5 Plus, Leagoo M8, Nomu S10, and Nomu S20.
According to Dr.Web a software developer from Shanghai, China is responsible for the infection.
“The analysis of this application showed it is signed with the same certificate as Android.MulDrop.924. Doctor Web previously wrote about this Trojan in 2016. We can presume the developer that requested adding the additional program into the mobile operating system image can be connected expressly or implicitly with the distribution of Android.Triada.231” Said in the blog post published by Dr.Web.
