Aren't apps on android hermetically sealed from other apps and malware. How could this be achieved ?
Since the other reply was unhelpful: apps are supposed to have limited privileges and isolation from each other, yes... But the whole point of malware like this is that they figure out ways to break those restrictions and get escalated privileged.
You can get more technical detail from reading the report, in this case it looks like the app does not contain malware, but instead requests an update after install that contains the bad code and then breaks the app limitations and scans for the target banking applications and copies the security certificates.
