Is there some website that give us the possibility to download malware APK in order to study it? I’m interested to study the abuse of android.permission.RECORD_AUDIO in Android 8.
- Koodous has a huge collection of apks, searching in "detected" category may give you what you wanted.
- VirusShare is a general malware collection, requires registration, as far as I remember they have torrent tracker here and there are android-specific sample collection per year. I never tried to download something from there, but you can try.
- There are some collections on github, for example here
- malware bazaar - not too large collection, but better than nothing.
- Pithus - requires registration via github, allows apk search by permission, allows download when logged in.
Koodous requires to pay for access, most basic access that includes downloading costs around EUR 60 for month.
