It seems like a 'crazy' claim that John McAfee makes at the very beginning of this video, is it true?
"Over half of all smartphones, both iOS and Android are infected with keystroke logging software. This is a known fact.
People pay these pornography sites for the ability to put their key logging software on your phones. How do you think they make their money? It costs millions of dollars to maintain these massive databases and have the bandwidth to disperse this pornography, and yet you don't pay. Yes, you're paying."
If this is true, how is it possible? I thought usually to be infected you had to execute/ install something, and that most websites were safe since they're sandboxed in the browser be it on a Mac or iOS/Android.
If true, how would you go about finding traces to see if your Mac or Android for example were compromised? Is it even possible to do for a user? All I know is Malwarebytes on a Mac/Pc, but maybe that's not enough?
