The challenge for malware authors, therefore, is to see if they can bypass Bouncer’s checks and sneak their malicious Android apps into the Google Play store.
Security researchers Charlie Miller and Jon Oberheide claim to have found multiple ways for Android apps to realise they are being tested by Bouncer and behave differently during the examination. If apps hide their malicious intentions while they are being tested (in other words, tell the difference…
