hacking: security in practice
What is the purpose of metasploit if all of their exploits are known by most all anti-malware services?

I've been learning and working with metasploit in my own test environments lately and it's really helped me learn the process of exploitation and everything. But ive been noticing that metasploit really only works under very specific conditions such as windows7 devices and older that haven't been upgraded in a very long time, or for mobile devices if the target happens to allow 3rd party apps and actually clicks on the infected APK. On my test devices, even windows defender can pick up on all of this.

It seems that metasploit is really only meant to teach people about the concepts and really only works if the target laughably out of date or happens to have every single security control at zero.

Does metasploit really work in the wild? or is it really only confined to testing environments?

How does a mobile device exploit is created? How do vendors protect mobile devices?

Hello, I started my work with mobile forensics and security. We have a study fund and because I absolutely love my new job I want to be as knowledgable as I can get.

However, I am really struggling in finding books on these topics: 1. Security measures applied to their phones by different vendors (what is a locked bootloader and how it got locked, how some vendors prevent physical extractions of their devices from working, requiring a special da and auth files to unlock the bootloader, etc); 2. How are the exploits created, researched, applied to the device, how they work on the hardware level;

Same for iOS devices.

I appologies if this is not the sub for it, but I don't know which is :/
