No body is entirely 100% a security guru until they are attacked and notice that they have a loophole they need to cover, but some have been able to upgrade and cover their little mistakes by just being very careful and taking corrections from those who fall victim to hacks and exploits. As days go by, that’s how we will have to expand our knowledge on security and make sure that we are not left behind; even the most once-known secured devices are now discovered to have security issues that raise concern.
I've said this a lot of times, and I say it again: the security vulnerabilities are less about the device you are using and more about how you are using it. You can't be fooling around on the internet, downloading all sorts of things, interacting with literally anything you see on the device where you have your financial apps, and then expect not to have security issues. You should ask yourself the question: Have you been trying to stay secure and keep your device secure from unwanted access and exploitation? You should get your answer if you are honest with yourself.
It won't be wrong to say that those who become victims of hacks and exploitation or even phishing scams, they are the only ones to be blamed at first, and then the other things should be looked at, because I believe that if you are mentally aware of everything, and smart enough to act in a way that would never cause threats to your financial holdings or assets, you will never face any issues.
I have been in this industry for so many years, and believe me, in all those years, I have never been a victim of any of these things, and that is because I'm always careful about what I do.
