You cannot prevent hacking, there are always vulnerabilities existing.

This is human, you today make a mistake in programming, so you leave me a specific vulnerability I might search for.

Regarding the extortions that come through social media,

It happened with one from Saudi Arabia who extorted someone from us,

That he saw him put a picture of a cake, so he says to him my father's birthday and we made him a cake,

He said to him well come let's make a surprise for your father, go take a picture for me of your father and your mother and the cake and things

I mean he wants to try to take a video from the heart of the house.

And of course he made edits on the video and extorted the family.
