Graham Cluley describes How Android Nougat will help protect your password from ransomware – New condition will partially prevent unwanted Android lockscreen password resets. The new OS upgrade will change the resetPassword API so that it can set a lockscreen password, but can’t reset it.
Which means that the new OS won’t stop malware setting the password if the user hasn’t already set one. Which sounds like a pretty good extra incentive to set one if you haven’t already. However, it looks as though it will also stop security software from disinfecting an upgraded phone if it becomes infected.
Nougat (Android 7.0) is scheduled to be rolled out later this year.
I’ve posted some odds and ends of information on how ransomware affects various platforms on an AVIEN blog page here: Ransomware: Affected Platforms & Devices
