This is quite serious and alarming, have we got an official statement from Samsung? We need to know if our personal data including passwords, bank cards, banking apps impose a risk of getting into the wrong hands?
That risk changes if it turns out there are big security flaws in Samsung's source code. Now that hundreds of researchers and hackers are poring over Samsung's code, they might find vulnerabilities that Samsung engineers missed. If criminals find Samsung flaws, they'll try to make money from them by exploiting them or selling the information to other crooks.
So what can you do? If you have a Samsung phone or tablet, update its software today before the bad guys can figure out a way to pervert Samsung updates. Change the password on your Samsung account, and enable two-factor authentication on the account if you haven't already.
In the longer term, install and use one of the best Android antivirus apps, which will spot and block known Android malware. And hold off on installing Samsung software updates after the middle of this week until it's clear that the updates will be safe.
