Duck tape is the solution for everything
Mark Zuckerberg is one of the most powerful people in the technology world which means that you are not exactly in the spotlight of the hackers but he is.
Normally, you would expect him to use some expensive special software to be protected from the hackers but he already has a solution … DuckTape. Yes, he also covers his camera and microphone ( like some of us ) because hackers cannot hack something that is physical.
Anyway, again, it is proved that the Duck Tape is the solution for everything.
