I’m analysing #KevDroid samples the new #Android #malware discovered several days ago by #ESTSecurity
The samples are available on @koodous_project and @virusbay_io
In the 1st downloader, in the OnCreate method of the MainActivity, they checked if the package called is installed. If not, they display a message prompting the user to update the application
In the downloadapk method, they retrieves the payload from cgalim[.]com and saves it to the external device memory as AppName.apk
I like their log: Log.i("aaaaa", "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa”)
Interesting, the 2nd downloader is checking if the package com.aykuttasil.callrecorder is installed
Yeah, more samples to analyse!!!
2 more samples signed by the same “kevin”:

I uploaded them to @virusbay_io
Nothing shady here: the launcher activity of the payload is called MainTransparentActivity and start a RootingTask :D
To give you an idea of the payload capabilities, this screenshot is the list of all the available actions
This is the list of the command types, in this sample not everything is used
