So the developer assume that if there will be no sensor then the app is running under sandbox so the app will be immediately stopped using “kill” command and the malicious code will not
Infection Process with Anubis Malware
Initial analysis of Payload indicates that the code is similar to the Anubis Banking malware and it connected to the C&C server with Anubis linked aserogeege.space domain.
